Handling of chains and sprockets Chain Installation

Cautions

For safe work¡Always wear clothes suitable for work and proper

protection (safety glasses, safety shoes, etc.).¡In addition to site workers, other people near

the work site are also required to be careful.¡Strictly observe Section 1 "General Standards"

(prevention of danger by prime movers,revolution shafts, etc.), Chapter 1, Part 2 ofOccupational Safety and Health Regulations.

¡For working, keep things in order in andaround the work site.

¡Before installation, be sure to switch off thepower.Before installing, removing, lubricating orotherwise servicing a chain and sprockets, besure the main electric power switch and allsecondary power switches of the equipment areturned off. Also, take precaution to ensure thatpower will not be switched on accidentally.Furthermore, exercise care to prevent clothingor any part of the body from being caught bya chain, sprocket or other part during work.

¡When any lifting apparatus is used, neverstand beneath it.

Warning¡Do not partially replace a part of a chain.

Do not partially exchange a worn or damagedchain and sprockets. Replacing only the worn ordamaged part does not restore overall strengthand risks further breaking or destruction. Alwaysreplace the entire chain and sprockets.

¡Do not modify chains or sprockets.Most of the components of a chain are heat-treated. If they are reprocessed, strength isdiminished and breaking or destruction canresult.

¡Electroplating may cause hydrogen embrittlement.¡Welding may lower the strength of chains

and components due to a flaw or heat, andresult in destruction.

¡Annealing can lower the performance of productsand components and may result in destruction.

(1) Before installation, please read the previoussection (1).

(2) Use connecting links and offset links asdescribed below.When installing a connecting link or offsetlink, confirm its construction. (P17)

¡For installing the clip on the connecting link,refer to the method illustrated below.

¡For installing a cotter pin on the connectinglink, refer to the method illustrated below.

¡For installing a spring pin, refer to themethod illustrated below. Spring pins areused for interference-fitted connecting linksused in DIDHI-PWR-S, HK and HI-PWR-SHKseries (P50 ~ 59, P60 ~ 61, P62 ~ 63).

¡For installing a T-pin or S-pin, refer to themethod illustrated below.

• For installing a one-pitch offset link, followthe installation method for the cotter pintype connecting link, and for installing a two-pitch offset link, follow the installationmethod of the connecting link used.

For other special types of connecting links,please consult us.

Before handling chains and sprockets, please understand the respective structures and specificationscorrectly, and read the following cautions for using them safely.

For handling (See P127 ~ 137 and P329 ~ 342.)¡For handling, follow the instructions in this

catalog and in the instruction manual. Select,layout, install, adjust and maintain chains andsprockets in the way that is recommended toensure a high-performance installation.

¡When connecting a chain, employ an installationmethod suitable for the type of connecting link.

¡For the layout, installation, adjustment andmaintenance, observe both recommendedequipment instructions and cautions.

Warning¡Do not attempt to modify any components.

When assembling, never drill a hole on aconnecting plate to make it larger and neverfile a pin to make it thinner for smoothinsertion of the pin into the connecting plate.

¡Do not use used chains.Do not reuse clips and do not install a usedcotter pin, connecting link or any othercomponent for a new chain.

(3) For proper operation of a chain, install andadjust it correctly. (See P127 ~ 134 and P340~ 342.)

(4) After installing a chain and sprockets, confirmthe following before switching on the power:• Is the connecting link correctly and

securely connected?• Is the chain engaged with the teeth of the

sprockets?• Is the amount of lubrication proper?• Is anything likely to cause interference or

be scattered?• Is the safety cover correctly installed?• Is there anything interfering with the

safety cover?• Whether or not there is anything

interfering with the chain.• If there is anything abnormal about the

connecting link portion, etc. and whetherthe respective components of the chainare flawed, rusty or abnormal in any otherway.

• Do not stay in the rotation direction of thechain.

(5) If any abnormal noise is generated afterswitching on the power, switch off the powerand re-confirm.

Avoidance of Danger¡Install a safety cover.

For the apparatus with a chain andsprockets installed, be sure to install asafety cover. Any unexpected fracture maycause the chain to be thrown from thesprockets. In addition to a sufficientprotector, install a stopping device such asan overload limit switch or brake so as not tocause overload.

¡Check for chain interference.Any obstacle which interferes with a drivenchain and sprockets is dangerous andshortens the life of the chain and sprockets.Always check for any interfering objects, andremove them.

To prevent any serious accident caused by a chainand sprockets, and to prolong the life of the chainand sprockets, take the following maintenanceactions:

(1) Lubrication (See P.132 ~ 134 and P.342.)Except for some chains of special materialsor elements, most chain life can beprolonged with lubrication. A chain whichrequires lubrication will be shortened in lifewithout lubrication. For example, chainelongation, corrosion and stiff joint occurdue to wear of some chain parts.

(2) WashingIf a chain is used with a material such assand or metallic powder, the promotion ofwear, stiff joint, etc. will be caused,shortening life. Wash away such harmfulmaterials.For washing, dip the chain into kerosene,dry, and sufficiently lubricate. However, inthe case of O-ring chain, since the O-ringmay be deteriorated by kerosene, do not dipit for more than 10 minutes.For washing, do not use an acid, alkali,gasoline or highly volatile solventdetrimental to the chain and sprockets. Foran O-ring chain, do not use a wire brush.

(3) Adjustment of tension and timing ofexchange (See P130 ~ 131, P137 and P341~342.)Chains and sprockets are consumableproducts.The wear of a chain and sprockets causessag on the chain. Periodically check thechain for sag, and adjust the tension to theoptimum condition.If a chain and sprockets show any rust orharmful flaw in appearance, or if theelongation of a chain or the wear of asprocket becomes critical, immediatelyreplace them.

¡Do not use an offset link for lifting.¡Excessive oil on the chain will cause fouling

by scattering. Wipe off extra oil to prevent itfrom scattering.

¡For washing, do not use gasoline or highlyvolatile solvent. Furthermore, do not allowany material containing acid or alkali tocome in contact with it.

Even chains of the same kind and size have adifferent service life depending on the serviceenvironment, numbers of teeth of the sprockets,lubrication and other conditions. This also appliesto the life of sprockets. Chains and sprockets aredifferent in wear life. If a new chain is used on anold sprocket with worn teeth, failure or rupture ofthe chain may occur.When a chain or sprocket must be replaced,replace both the chain and sprockets.

If anything remains unclear, please consult us.

Cautions

Cautions for using roller chains for lifting

The "Mechanical Parking Area Technical Standard"sets the safety factors of ropes and chains as "5 forsystem A", "7 for system B" and "10 for system C".However, if a chain is used at a safety factor of 5 insystem A, the acting tension of the chain generallyexceeds the Max. allowable tension of the chain.That is, repeated use causes the chain to rupturedue to fatigue. Therefore, when a safety factor of 5for system A is adopted, periodically replace thechain under strict life control.

The connection between a chain and an end fitting(hereinafter called a fitting) is the section likely tocause troubles. For safety purposes, take thefollowing matters info account when you design.

3-1 General cautions(1) If the dimensional difference between the inner

width of an outer link of a chain and the width ofa fitting or the dimensional difference betweenthe pin diameter and the fitting hole is too large,a large bending stress acts to lower the pinstrength dramatically.Refer to "3-3 Dimensions of fitting" for your design.

(2) If the fitting hole suffers "wear" or "roll over" at itsends during use, the strength of the pin greatlydeclines as in the case of (1). Periodically check,and if "wear" or "roll over" is found in the fittinghole, replace the fitting.

(3) Rust or corrosion is the major cause ofdeterioration of strength. Apply grease to chainsperiodically to prevent rust.

(4) If a partial load, lateral load or torsional load actson a chain, the strength of the chain declines. Toprevent it, exercise sufficient care in thehorizontality of fitting of the hole, installationaccuracy of fitting, etc.

3-2 Material of fitting and heat treatment(1) Hardened fitting

The fitting is generally hardened and tempered.Thoroughly examine the size and materialhardness of the fitting, and select a materialwhich ensures a sufficient hardness.

a. In general, select a material which ensures therequired hardness from tough hardening steels(SCM435, SCM440, etc.) and medium carbonsteel.

b.Harden the fitting, and temper at a hightemperature, avoiding the temper brittlenessrange, to a hardness of about HRC30 to 45.

c. In the case of a threaded fitting, keep thehardness at not higher than HRC40, to lower thesusceptibility of the threaded portion to delayedfracture.Select the size of the threaded portion toachieve a tensile strength not lower than thetensile strength of the chain.

(2) Non-hardened fittingIf the fitting is used without being hardened andtempered, the following must be considered.

a. Since the fitting hole is likely to suffer fromwearing during use, press a hard bushing intothe fitting hole.

b. Since the strength of the fitting is lower thanthat of a hardened and tempered fitting,

Safety factor1

Based on the "Chain Safety (Technical) Standards" and "End Fittings" proposed by Japan Chain Association tothe Japan Parking System Manufacturers Association Incorporated and multilevel parking machinemanufacturers in February and October, 1993, the cautions necessary for using roller chains (hereinafter calledchains) for lifting are stated below.

2-1 Max. tensionThe Max. tension allowed to apply to a chain is setat not higher than the value obtained by dividingthe minimum tensile strength of the chain by asafety factor. However, be sure to examine theselecting methods recommended by us (See P120and 121), and adopt a safer method.The Max. tension corresponds to the "correctedchain tension" which includes dynamic load atstarting and stopping in addition to offset load by amotor vehicle (difference in weight between frontand rear wheels, horizontal shift of the motorvehicle in reference to a pallet, offset load due tothe chain lifting position, etc.)

2-2 Connecting link of chainA general connecting link (R type and C type in thiscatalog) has pins clearance-fitted in the connectingplate holes.The connecting link is lower in fatigue strength thanthe base chain. When a connecting link higher infatigue strength is necessary, use a specialconnecting link with pins interference-fittedconnecting plate holes (F type or H type in thiscatalog).In this case do not use any offset link (OJ or 2POJ).As for the types of connecting links, see P16 ~ P17.

How to Order Roller Chains for Power Transmission

Installation of connecting linkThe connecting link isseparate from the chain.

The connecting link isconnected with the chainto form a loop.

The connecting link isconnected with the chain,without forming a loop.

*When you place an order, refer to "Set Number of Chains and Links" (P138).

DID general application chains can be classified into two types in reference to strength; standard series chainscomplying with ANSI roller chains and HK series chains complying with ANSI, which have outer and inner plates thickerthan those of standard chains.

The standard series include two lines; standard roller chains, and HI-PWR-S chains improved in fatigue strength andshock resistance compared to the standard roller chains. You can use them as basic transmission chains for allapplications ranging from low speed to high speed.

The HK series are improved in the strength of plates to allow heavy duty transmission mainly in a low speed range, andinclude two lines; HK roller chains and HI-PWR-SHK roller chains further enhanced in fatigue strength.

SprocketsThe simplex chains can be engaged with standard sprockets of the corresponding nominal numbers. For sprockets, see P115 ~.

Selection of chainsFor selecting a standard roller chain or HI-PWR-S roller chain, refer to "Selection of Chains" (P120). However, only for aspecial case of low speed and less shock, "Low-speed selection method" (P121) can also be referred to.For selecting an HK roller chain or HI-PWR-SHK roller chain, refer to "Slow-speed selection" (P121). For selecting a connecting link or offset link, refer to "General selection". Since selection according to "Slow-speedselection" results in insufficient strength, please consult us.

Number of chain strands and method for connecting outer plates with pinsFor the numbers of available strands, refer to the table of "Dimensions" for each size of chain.The standard method for connecting pins and plates is rivet type (RP).The cotter type (CP) can be used for standard chains and HK chains of DID80 or larger.* As for HI-PWR-S chains and HI-PWR-SHK chains, only rivet type (RP) is available.

Connecting links and offset linksFor connecting links and offset links, refer to the table of "Dimensions" for each size of chain.This section describes general application chains only. However, since many kinds of engine mechanism chains and agricultural roller chainsare also available, please see the sections describing the respective items.

A roller chain has a structure as illustrated below, and the names of the components are stated in the drawing. Thesecomponents act as described below, and are designed to suit the respective actions.

Connecting linksThe following four types of connecting links are available(R, F, C and H).

Offset linkAn offset link is used for increasing or decreasing thelength of a chain by one pitch, and the following twotypes are generally available.

Since the "connecting link" and "offset link" are lowerthan the base chain in strength, consult us when usingthem for any service condition in excess of the Max.kilowatt ratings.

* Clearance fitIn this fit, a clearance is always formed between thepin and the hole when they are assembled. Thismethod is used in standard connecting links.

* Interference fitIn this fit, an interference always occurs when the pinand the hole are assembled. This method is adoptedin base chains and H connecting links. However, in Hconnecting links, the interference is smaller than thatof the chain body.

Pins support all the load acting on the chain, together with inner and outer plates, and when the chain is engaged with a sprocket,the pins slide as bearings. They are required to be high in shearing strength and bending strength, and especially wear resistance.P

in

Bushings act to prevent the shock received through rollers when the chain is engaged with a sprocket from being directly transmitted topins, and also act as bearings, along with the pins. So, they are required to be high in shock fatigue strength and wear resistance.Bu

shing

Rollers act to smoothly bend the chain when the chain is engaged with a sprocket, to protect the chain from shockwith the sprocket. They are required to be high in shock fatigue strength, collapse strength and wear resistance.R

olle

Plates are subject to repeated tension of the chain, and sometimes a large shock. So, they are required to behigh in tensile strength, and also in shock resistance and fatigue strength.P

Selection of chainsFor selection of a chain, see the tables of "Max. HorsepowerRatings" for standard roller chains (P20 ~ P47) and"Designing of Chain Transmission" (P120 ~ P126).However, only for a special case of low speed and lessshock, "Low-speed selection" method (P121) can also bereferred to.

Standard roller chains up to five strands are available.The standard method for connecting pins and plates isrivet type (RP).The cotter type (CP) is available for standard chains andHK chains of DID80 or larger.

SprocketsThe standard roller chains can be engaged with standardsprockets of the corresponding nominal numbers. Forsprockets, refer to the table of "Dimensions" for each sizeof chain.

Connecting links and offset linksFor connecting links and offset links, refer to the table of"Dimensions" for each size of chain.The connecting links are generally R or C connecting linksin which the pins are clearance-fitted with the connectingplate. Since clearance-fitted links are inferior to the basechain in Max. allowable tension as in the case of one-pitchoffset links (OJ), "Low-speed selection" (P121) cannot bereferred to. Since the Max. kilowatt ratings are decidedconsidering the strength of connecting links and OJ, theclearance-fitted connecting links and OJ can be used if thechains are selected according to the "General selection".When a higher Max. allowable tension is required for theconnecting link, use the interference-fitted connecting link(H connecting link) of a HI-PWR-S chain, and in the case ofoffset links, use 2POJ. For details, refer to the table of"Dimensions" for each size of chain.

Note: 1. Determine the required bore size less than the Max. value shown above takingstrength reduction into consideration.

2. DID's finishing process is the basic application to the bore surface finishing fordoubled sprockets of B type and C type.

3. For double C type sprockets, three or four types of bore size are available in 26and larger number of teeth than that. The bigger standard bore is applied incase the required bore size ranges between the two types of bore size.

4. Heat treatment on teeth portion is available when requested.

Note: 1. Determine the required bore size less than the Max. value shown above takingstrength reduction into consideration.

2. DID's finishing process is the basic application to the bore surface finishing fordoubled sprockets of B type and C type.

3. For double C type sprockets, three or four types of bore size are available in 26and larger number of teeth than that. The bigger standard bore is applied incase the required bore size ranges between the two types of bore size.

4. Heat treatment on teeth portion is available when requested.5. Due to production reasons, Carbon Stell may be used for those with 13 ~ 21

teeth without notice.

(Double B type)


(Single B type)


(Single BW type welded)Double sprocket with hub on one side

(Double C type)

Note: 1. Determine the required bore size less than the Max. value shownabove taking strength reduction into consideration.

2. Given dimensions of bore and DH and L of hub to those with 21teeth and larger is reference. Please consult with us about themwhen ordering.

3. DID's finishing process is the basic application to the boresurface finishing for double sprockets of B Type and C type.

4. For double C type sprockets, three or four types of bore size areavailable in 26 and larger number of teeth than that. The biggerstandard bore is applied in case the required bore size rangesbetween the two types of bore size.

5. Heat treatment on teeth portion is available when requested.

HI-PWR-S Type Roller Chains

HI-PWR-S roller chains are enhanced in fatigue strengthand impact strength without changing the dimension inthe pin length direction of standard roller chains. Platesare enlarged, and the machining accuracy andassembling accuracy of components are improved. Theroller chains hold high transmission efficiency forapplications from low to high speeds and are powerfulenough to withstand long-term use.

Recommended uses¡Compared to standard roller chains, HI-PWR-S roller

chains are higher in maximum kilowatt rating by about30 percent in a medium to low speed range. Theyexhibit excellent capability in places where largeshock loads are applied, drive units for frequent start/stop, and also in high speed applications.

<Examples>¡Civil engineering machines such as skid steer,

trenchers, trucks, cranes, agitating trucks, forkliftsand drive units for conveyors, elevators, stackers, etc.

Selection of chainsIn general, select your chain with reference to "Designing of Chain Transmission" (P120~126) and also to the tables of"Drive Performance" and "Dimensions" of HI-PWR-S type roller chains (P52~59)However, only for a special case of low speed and less shock, "Low-speed selection" (P121) is also applicable.

SprocketsHI-PWR-S Roller chains and ANSI standard chains are the same in basic dimensions. Use ANSI standard sprockets.

Connecting links and offset linksUse H connecting links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted with the connectingplate. For the connection between the connecting plate and the connecting pins, spring pins are used instead of cotterpins for a standard roller chain. The center plates of an H connecting link for multiplex chain has bushings pressed in.

HI-PWR-S roller chains do not have any offset link. Use an even number of links.

Never make the holes of the connecting plate larger and never make the pins thinner to facilitate the work for fitting thepins into the connecting plate, since otherwise the fatigue strength will be lowered.

HK Type Roller Chains

Selection of chainsSelect a proper HK type roller chain based on "Low-speed selection". (P121)For the maximum allowable load, see the following tableof dimensions.

HK type roller chains are available up to triplex.

SprocketsUse standard sprockets for a simplex HK roller chainSince the transverse pitches (C dimension: see P61) arelarger than those of standard chains in the case ofduplex or triplex, standard sprockets cannot be used.Refer to the sprocket tooth profiles for HK. (see P116~117)

Connecting link and offset linkThe tensile strength of connecting links and offset linksare listed on the left, but the maximum allowable load islower than that of the base chain. Please consult usshould you have any questions. It is recommended touse the connecting link of interference-fitted. (FJ, HJ)

Never make the holes of the connecting plate larger andnever make the pins thinner to facilitate the work forfitting the pins into the connecting plate, sinceotherwise the fatigue strength will be lowered.

HK type roller chains conform to H type of ANSI, andtheir thickness of inner and outer link plates are equal tothose of the next larger size chain. Therefore, HK typeroller chains are higher in tensile strength by about 20%and in maximum allowable load by about 15% thanthose of standard roller chains. Since the weight of thechains is also larger, HK type roller chains are suitablefor the application of heavy duty at low speed.

Recommended uses¡Optimal for places where higher strength is required

but large and heavier chains cannot be used.

HI-PWR-SHK Type Roller Chains

The DID HI-PWR-SHK roller chains have thicker linkplates than HI-PWR-S roller chains, and are the highestin tensile strength and allowable load among generalapplication chains, thus being suitable for low speedheavy duty transmission.

Recommended uses¡The HI-PWR-SHK roller chains are 25 percent higher

in tensile strength and 50 percent higher in maximumallowable load than the standard roller chains, butsince their weight is heavier, driving performancedeclines at high speed. So, they are suitable for heavyduty at low speed applications.

<Examples>Multilevel parking machines, pipe benders, constructionmachines, etc.

Selection of chainsSelect a proper HI-PWR-SHK type chain based on "Low-speed selection" (P121)For the maximum allowable load, see the following table of dimensions.HI-PWR-SHK series is available in simplex.

SprocketsStandard sprockets for multiplex chains cannot be used.

Connecting links and offset linksThe best feature of the HI-PWR-SHK roller chains is high maximum allowable load. Therefore, interference-fittedconnecting links (H connecting links) with little strength degradation are used.The connecting plate and the connecting pins are connected with spring pins. The tensile strength of an H connectinglink is equivalent to that of the chain, but the allowable load is somewhat lower than that of the chain.

HI-PWR-S type roller chains do not have any offset link. Use an even number of links.

Never make the holes of the connecting plate larger and never make the pins thinner to facilitate the work for fitting thepins into the connecting plate, since otherwise the fatigue strength will be lowered.

Solid Bushing Chain (HT/D), (D)

Solid Bushing chain is highly wear-resistant using coldformed solid bushings with a seamless smooth surfaceand complete roundness.This is the popular type among the Ultimate Life ChainSeries with its improved grease retention between thebushing and the pin.The solid bushings and our patented V grease extendthe wear life from up to 4 times compared to standardroller chains. We recommend you to adopt this solidbushing chain if you are wishing to reduce the frequencyof maintenance.

Recommended uses¡For improving wear resistance while retaining the

merits of standard roller chains.¡For Circumstances where chain elongation occurs

frequently or lubrication is difficult.

＊Wear resistance can be further enhanced when DH-αcoating pins are used.

DH-α Chain (DHA)

Perfect lubrication makes chain life longer. It is not easyto avoid deterioration due to its own oxidation andmixture with contaminants. In this case, DH-α chainshows good performance. Excellent performance canbe expected under non-lubricated conditions and insuch critical conditions where dirt, dust or fine metalparticles work into the chain.

Recommended uses¡Environments where soil, sand or dust directly comes

into contact with the chain (O-ring chains arerecommended if applicable.).

¡Applications where a chain is lubricated in an oil bathand the oil is heavily deteriorated due to thecontamination of foreign objects.

¡To avoid chain kinking by heat between pin andbushing.

The pin with a super-hard surface coating protects the critical area from adverse environments

Structure of DH-αDH-α refers to a hard layer formed on the surface of apin. This layer contains harder carbide as illustratedbelow, so it provides excellent wear resistance even inthe use for adverse conditions such as the contaminationof hard foreign objects as well as in oxidation resistance.(Patented) Microstructure

The white layer is a layer by DH-α treatment, and theblack grains visible in the layer are chromium carbide.

Selection of chainsThe strength of DH-α chain is the same as that ofstandard roller chains. For selecting a suitable DH-αchain, refer to "Selection of Chains" (P120~123).

Connecting links and offset linksUse the connecting links and offset links for standardroller chains. While a chain has many links, the numbersof connecting link and offset link is 1 or 2, and,therefore, their influence on the wear of the entire chainis small.

SprocketsThe dimensions of DH-α chain is the same as those ofstandard roller chains. Use standard sprockets forstandard roller chains.

O-Ring Chain (LD)/X-Ring Chain (LX)

The durability of chain is dramatically improved sincegrease is sealed between the pins and bushings by O-rings. The O-ring chain is the most dependable model ofthe Ultimate Life Chain Series with its excellent wearresistance even in the conditions or environments wherechain maintenance is difficult.

Recommended uses.¡Circumstances where frequent chain replacement is

required due to wear stretch.¡Circumstances where lubrication during the service is

impossible.

¡In an environment with much soil, sand, dust, etc.¡Applications that require strength higher than that of

a sintered bushing roller chain.

Other features¡Reducing noise. (The noise level is 3 dB lower compared

to standard roller chains.)¡Reducing vibration with the friction created by O-

Ring. (The power loss due to the friction is almostnegligible, since the frictional force between the pinsand bushings is for usually in the applications.)

SprocketsO-ring chain uses longer pins than a standard rollerchain. When using multiplex O-ring chain, the standardsprocket for multiplex chains cannot be used.

CautionO-ring chain is not recommended in applications wheresolvents or other substances may attack “Nitric Rubber”.Special material O-rings are also available for theseconditions: Please consult us for details. In general,“Nitric Rubber” is damaged by contact with the followingchemical materials.

Gasoline, Light oil, Benzene, Toluene,Trichloroethylene, Ether, Ketone (MEK), Ethyl acetate,Phosphoric acid, Ester hydraulic oil, Organic acid,High-concentration inorganic acid

Selection of chainsThe strength of an O-ring chain is almost the same asthat of a standard roller chain. (Since the pins are longerthan those of standard roller chain, the average rupturestrength is slightly lower.)For selecting a suitable chain, refer to "Selection ofChains" (P120~123).When the service ambient temperature is higher than 80° C, special heat resistant O-rings must be used. In thiscase, contact us for more information.

Connecting links and offset linksTwo types of connecting links are available: clearancefit and interference fit. When high strength or durabilityis required, use interference-fit connecting link. Only2POJ is available as the offset link for all sizes.

Selection of chainsAs for sintered bushing roller chains, the inner plates are thicker and the pins are longer than those of standard rollerchains in order to compensate for the strength lowered by the use of sintered bushings.For selecting a suitable chain, refer to "Selection of Chains" (P120~123). Use the tables of maximum kilowatt ratings forsintered bushing roller chains that cover low speed ranges (P76~79).For sintered bushing roller chains, "Low-speed selection" cannot be used since the "Maximum allowable load" in thedimension table considers only the chain tensile tension and neglects the bushing strength.

Connecting links and offset linksFor sintered bushing roller chain, R connecting links are used for DID60 or smaller, and C connecting links for DID80 orlarger.OJ can be used as offset links. Please place an order the connecting links and offset links specifying the type forsintered bushing roller chain.In the tables of maximum kilowatt ratings, the strength of the connecting links and offset links are taken into account.

SprocketsStandard sprockets can be used for sintered bushing roller chains.

Nickel Plated Chain (N)

The surface of Rustless Chains is nickel plated for anappealing exterior and corrosion resistance. It willexhibit excellent corrosion resistance especially whenused in combination with grease lubrication. You canexpect the effect to delay hydrogen brittle destructionwhen used in circumstances where chains are exposedto sea breeze or acidic sprays.

Features¡The chain is protected even when in use with gilding

or alumite machines that emit corrosive steam.The effectiveness of rust resistance and corrosionresistance of the nickel plating does not deteriorateeven under conditions of high temperature andcontinues to protect the chain.

¡The chain's fine exterior makes it ideal for machinesfor demonstration.

Recommended uses¡When a clean appearance is preferable

Food sanitation machines, office machines, textilemachines, printing machines, pulp processingmachines etc.

¡When using in a corrosive environmentChemical machines, gilding machines, alumitemachines

¡When a neat exterior is necessaryDemonstration machines at exhibitions etc.

Specialized nickel plating for a neat and clean appearance and corrosion resistance

Hi-Guard Chain (E)

Hi-Guard Chain has higher corrosion resistance next tostainless steel chains. The surface of the chain isfinished in non-gloss white highly protective coating. Ithas superb resistance to anti-corrostion and rusting. Ithas equal strength to standard roller chains, and can beused in circumstances where strength higher than thatof stainless steel chains is required.

Features¡Since high guard coating acts as a sacrificial anode for

the chain body, you can expect sufficient corrosionresistance even when the coating has come off tosome extent.

¡The coating consists of environmentally friendlychromium free material. To comply with the EU'sRestriction of Hazardous Substances (RoHS) Directive,hexavalent chromium is not used.

Recommended uses¡Applications require both strength and corrosion

resistance.Multilevel parking facility, moving decks, cleansinglines etc.

¡Conditions exposed to rain or sea waterMachines installed outside, amusement machines.

Double Guard Chain is highly corrosion resistant with coatingof double layers of two different materials. Compared to theHigh-Guard Chain, it exhibits nearly doubled corrosionresistance in the salt water spray test, and can be used inmild alkaline and mild acidic conditions.

Features¡With its improved corrosion resistance, it can be used in

circumstances where High-Guard or Rustless Chainscannot be used, and even in some conditions where onlystainless steel can be used.

¡The coating consists of environmentally friendly non-chromematerial. To comply with the EU's Restriction of HazardousSubstances (RoHS) Directive, hexavalent chromium is not used.

Recommended uses¡Conditions that require both strength and corrosion

resistance.Multilevel parking facility, moving decks, cleansing lines etc.

¡Conditions exposed to rain or sea water.Machines installed outside, amusement machines.

¡Conditions exposed to mild alkaline and mild acidicchemical agents, sea water or wastewater. Variouschemical plants and water treatment plants.

Stainless Steel Chain (SS/SSK)

There are two types of Stainless Steel Chain: SS and SSK.The SS type has the highest resistance to corrosion andheat. However, it is made entirely of austenite stainlesssteel and thus its tensile strength is slightly lower than70% of a standard roller chain, and maximum allowableload drops to a little over 10%.By using precipitation hardened stainless steel for thepins, bushes and rollers, the SSK type has 1.5 timeshigher maximum allowable load compared to the SStype. Select SSK when you need more strength than SS,or desire longer product life.Both types have equivalent corrosion resistance.

Recommended uses¡Conditions exposed to mild alkaline and mild acidic

chemical agents, sea water and wastewater. Variouschemical plants and water treatment plants.

¡Conditions of high temperatureHeat-treating furnaces, dry furnaces, incinerators

Excellent resistance to corrosion and heat that allows use in almost everywhere

Selection of chainsThe average tensile strength and maximum allowableload of the Stainless Steel Chain are both lower than astandard roller chain. Refer to the maximum allowableload for the selection of chains.

Connecting linksR connecting links are used for Stainless Steel Chains#60 or smaller and C connecting links for #80 or larger.

SprocketsThe pins for the X-Ring chains are longer than those ofstandard roller chains, and thus standard sprockets formultiplex chain cannot be used for the X-Ring chainswhen using this chain in multiplex.

CautionqAs a general property of stainless steel, stress

corrosion cracking and pitting corrosion can becaused by chlorine and chlorine ion (CR-).

wThe chart on right shows the data of tests on the levelof corrosion resistance for each medium and doesnot guarantee the performance of the chains. Pleasetake into consideration the conditions, temperature,level and other overall situation when using.

Selection of chainsThe maximum allowable load of Low-temperatureResistant chains differ by temperature. Please refer tothe table in the previous page for chain selection.Please refer to P120~122 for other criteria. If used innormal temperature, better shock resistance can beexpected compared to standard roller chains.

Connecting links and offset linksR connecting links are used for Low-temperatureResistance chains #60 or smaller and C connectinglinks for #80 or larger. There are no offset links.

SprocketsStandard sprockets can be used for Low-temperatureResistance Chain as their dimensions are equivalent tostandard roller chains.

CautionPlease use lubrication oil for cold resistance for themaintenance of the chain.

Bicycle ChainBicycle chains are emblematic of the DID brand, and wewere founded originally for the production of bicyclechains. They have been used in many bicycles made inJapan and worldwide countries.Recently, our Hi Guard Chain (E) with an additional rustpreventive treatment has favorable reputation by users.The bicycle chains have been continuously examinedand improved in performance, quality and specificationsas seen in the availability of current products. As aresult, they are the lightest and most compact chainsamong products of the same size. Presently, they areused not only for bicycles but for many purposes suchas the driving of vending machines and agriculturalimplements and for conveyor systems.

Small Pitch ChainThe smallest chain complying to ANSI is DID25 of 6.35 mm pitch.However, in response to the demands for smaller chains inrecent years for high technology machinery such as officeequipment, medical machines and industrial robots, we provideDID15 of 4.7625 mm (3/16 inch) pitch and also DID15H1 as ahigh-power version of DID15. These high precision chains aremanufactured under severe quality control especially requiredfor small sizes, taking wear resistance also into account.

Selection of chainRefer to the "Low-speed selection" (P.121). However, the chainoperation speed can be set considerably high depending on thetype of lubrication as shown in the table below.

Connecting links and offset linksR connecting links are used for small pitch chains. However,since their strength is lower than that of the base chain, andsince the clip is likely to come off in high speed operation, theuse of connecting links is not recommended. Use a loop chainwithout attaching connecting links.Offset links are available for chains other than DID15 andDID15H1, but their use is not recommended for the same reasonas stated for the R Connecting links.

DID15: A high precisionmini-pitch bushing chainthat is smaller than acompact drive chain forgeneral applications,DID25

DID25: Smallest bushingchain among ANSIstandard chains usingcurl bushings.

DID35: A ANSI standardbushing chain suitablefor small precisionmachines that requirehigh strength.

Engine Mechanism ChainDue to the extremely high technical demands derived fromthe development of the automobile industry, rapid strideswere made in the development of engine mechanismchains such as timing chains for driving cam shafts on 4-cycle engines used in motorcycles and motor vehicles,chains for driving oil pumps, generators and other auxiliarymachines, and chains for driving balancer shafts. We haveworld class technical expertise in this area. The DID enginemechanism chains have excellent wear resistance, fatiguestrength, silencing effect and shock strength capable ofwithstanding high speed operation, and can meet theconditions required for today's powerful yet down-sizedhigh performance engines. For silent chains, see thesection for silent chains in this catalog.

Silent Chain

SC silent chains (SCA, SCR, SC)SC silent chains use specially-coated round pins andspecial plates to achieve an ideal engagementmechanism, and can keep a noise level remarkablylower than conventional roller chains.SC type silent chains can be used for high speed andlarge tension transmission just like a toothed metallicbelt since the plates directly engage with the sprocketsfor driving.SCR-04 silent chains are designed with inner engagingstructure for further reduced noise level.

Silent Chain

PS silent chainA PS type silent chain has a structure in which a set ofspecially formed connecting pins and locker pinscontact each other while rotating at each flexiblebearing position. Thus, it generates less heat especiallyin high speed operation and is excellent in durability.Furthermore, the specially formed pins greatly reduceshock when the chain is engaged with sprockets,providing a higher silencing effect than SC silent chains.

SprocketsSprockets for DID silent chains adopt special modulesin involute tooth forms for the SCA 04××, SC 25××,SC 06×× on the previous page and PS silent chains toensure silent high speed operation. For all sizes, thesprocket tooth heads are usually hardened by inductionhardening or carburizing.

Roller Chain Coupling

Features

1. Simple structureA roller chain coupling consistsof one duplex roller chain andtwo sprockets for a simplexchain. Handling is very simpleas both the shafts (drivingshaft and driven shaft) can beconnected and disconnectedby inserting or removingconnecting pins (cotter type).

2. Easy alignmentOwing to the play between the respective componentsof the chain and the play between the roller chain andthe sprockets, the eccentricity and angle error can begenerally allowed as follows:

3. Small but powerfulSince a powerful roller chain is engaged with thesprockets at all the teeth, a large torque can betransmitted, though the coupling itself is smaller thanother kinds of couplings.

4. Excellent durabilityThe roller chain is made of heat-treated steel andmanufactured precisely and solidly to the highestmanufacturing standard. The durability is outstandingand little time is required for maintenance as thesprockets have induction-hardened special teeth, andare always engaged with the roller chain.

5. Protection of machineRational flexibility decreases vibration, overheating andwear of the bearings caused by the eccentricities andangle errors of the shafts.

Standard housingThe standard housings forNo. 8022 or smaller are madeof aluminum alloy die casting,and those for No. 10020 orlarger are made of aluminumalloy casting. Installation ofhousings has the followingadvantages.

1. Advantages of housing¡Holding of lubrication

Since a roller chain coupling rotates with flexibility,the teeth of the roller chain and sprockets slideslightly during operation. So, they must be keptlubricated for prevention of wear as much aspossible. The housing functions as a grease box forthe lubrication.

¡Prevention of grease scatteringEspecially in high speed rotation, grease may bescattered by centrifugal force. The housing functionsas a protector that prevents this.

¡Protection from dust and moisture (corrosive atmosphere)When a roller chain coupling is used in a wear-causing or corrosive circumstances, the chain life isextremely shortened unless the coupling is perfectlyshielded from the circumstances. The housingfunctions to protect the roller chain coupling,preventing the shortening of life.

¡High safety and neat appearanceSince the housing has no protrusions outside, it issafe even if it rotates with the roller chain coupling. Itis also neat in appearance. (To avoid possible injury,do not touch the housing when rotating.)

2. StructureThe roller chain coupling can be split in the directionperpendicular to the shafts. The hole on the drivingshaft side of the housing firmly holds the coupling'ssprocket hub. The hole on the driven shaft side keeps aclearance of 1 mm or more from the sprocket hub tomaintain flexibility of the coupling. Oil leakage from thisportion is prevented by a seal ring.

¡Eccentricity ε: Up to 2% of the roller chain pitch

When the roller chain coupling is used for high speed rotation (in the range oflubrication types B and C), keep the allowances less than half of the above.

¡Angle error α: Up to 1°

¡Always wear clothing suitable for work and properprotection (safety glasses, safety shoes, etc.).

¡Strictly observe Section 1 "General standards(prevention of danger by motors, revolving shafts,etc.), Chapter 1, Part 2 of Occupational Safety andHealth Regulations.

¡Be sure to switch off the electric power source or anyother power source before starting maintenancework, and ensure that the power is never accidentallyswitched on. Furthermore, make sure not to allowyour clothes or any parts of the body to be caught bythe chain or sprockets, or by any other nearbyequipment.

¡Be sure to install a chain housing for type C and typeB (see "Table of Lubrication Types").

¡For installing the roller chain coupling into a high-speed machine or heavily vibrating machine, coat thebolts with a loosening preventive.

¡Install a safety cover to prevent any unexpected flyingof loosened bolts, or scattering of a broken housingor chain.

¡Never partially replace or re-use the coupling as itsstrength will be lowered, causing damage ordestruction. Furthermore, since the coupling is heat-treated, never modify the cotter holes or any otherparts. When replacement is necessary, replace theroller chain coupling or housing as a set respectively.

¡Noise during operation may be caused by malfunctionand the unit may need to be replaced. Immediatelyswitch off the power, and check the cause.

Lubrication of roller chain couplingThe lubrication of a roller chain coupling belongs to thefollowing three types: A, B and C, depending on thespeed of rotation used. Refer to the table of Max.Horsepower Ratings (P112).

1. Lubrication types

2. GreaseSince a roller chain coupling is usually used at highspeed for a long time, grease must satisfy the followingconditions.™Excellent in mechanical stability, oxidation stability

and adhesion.™Grease based on metallic soap: For low speed

operation, grease based on sodium soap, i.e., fibergrease can be used, but for high speed operation (forlubrication type B and C), be sure to use greasebased on lithium soap.

3. Greasing amountFill appropriate amount of grease in the housing inaccordance with the following table.Type A

Type B

Type C

Greasing once a month.

Greasing every 1 ~ 2 weeks, or install alubrication housing.Be sure to install a housing, and replacegrease every 3 months.

DID C-Top (Chain Cover) PAT.

DID Chain Lube (420 ml)/ DID HI-PWR Lube (330 ml)

Chain Wear-elongation Check Gage

DID C-Top is a plastic cover for chains that can be easily attached. It hassufficient load strength for chains conveying goods. Unlike conventionalplastic chains, it can be used under high tension as stainless steel chains.It is an ideal solution for the use that requires the strength of steel chainsfree from concerns of damaging, soiling, and jamming of products. It alsoprevents operators from being caught by the chains. It can also be used asthe cover for chains used for elevating devices such as multilevel parkingmachines.

Chain Lube is a spray type lubricant that was developedspecifically for chains. It has outstanding features thatlengthens the chain life preventing it from wearing andmaximizes the chain's transmission efficiency.

This gage checks the wear-elongation of chains.¡Check the chain elongation at a portion which is most

frequently engaged with the sprockets (portion mostlikely to be worn).

¡When the center of the pin of the chain to be measuredreaches the arrow point, it means that the chain has beencritically elongated. In this case, replace the chain.※Use the gage to check the wear elongation of your chain.

Types, construction and materials

General terms for sprockets

Nominal number of sprocketsThe nominal number of a sprocket is the same as thenominal number of the corresponding chain. Forexample, Chains such as DID50, DID50HK, and DID50LD can be engaged with a sprocket DID50. It isfollowed by symbols and characters indicating thenumber of chain strands, the number of sprocket teeth,hub type, tooth head hardening, etc.

Diameter of prepared hole and shafthole finishingA standard sprocket for a single strand or double strandchain has a shaft hole prepared at a diameter stated inthe table of dimensions. When you finish the shaft hole,machine it in reference to the outer diameter or rootdiameter. For reference, the table of ANSI key slotdimensions is shown on P113.

Hardening of tooth headsThe teeth of a sprocket must be tough and wear resistantas they are impacted when engaged with the rollers ofthe chain and worn by sliding with the rollers. Whensevere wear and large shocks are anticipated, sprocket

made of carbon steel or cast steel should be used andhigh-frequency hardening should be conducted.The standard sprockets DID40 to DID120 with a hub ononly one side for single and double strand chains areinduction-hardened even if the number of teeth is small.Whether the product is induction hardened or not isshown in the tables of dimensions of respective sprocketsfor your reference. Furthermore, in the following cases,induction-harden the teeth of the sprocket.¡The small sprocket has 20 or less teeth and is used

at 1/6 or more of the maximum speed stated in thetable of maximum kilowatt ratings.

¡The small sprocket is used at a change gear ratio of4:1 or more.

¡The small sprocket is used for a low speed largeload transmission as in cases of selection based onthe "Low-speed selection".

¡Sprockets are used in circumstances where theteeth are heavily worn.

¡Sprockets are used under conditions where thereare frequent starts and stops or sudden regular orreverse rotations.

General cautionsFor selecting the number of teeth and speed ration of thesprocket, see "How to select proper chain" (P120~123).For cautions for installing a sprocket on a shaft andreplacement timing, see "Installation adjustmentmaintenance" (P127~137).

Dimensions of SprocketSprockets can be classified into standard sprockets, HKsprockets and other sprockets.

1. Standard sprocketStandard sprockets are ANSI sprockets which can beengaged with standard series roller chains. See P125 fordimensions.There are two types of tooth profiles: U-tooth and S-tooth.See P119 for tooth profile.

2. HK sprocketHK sprockets can be engaged with HK series roller chains,and those for single strand chains are identical to standardsprockets. However, sprockets for multiple strand chainsare different from standard sprockets in sprocket toothprofile. See the corresponding table in P117.

3. Other sprocketsOther sprockets are designed according to the followingcalculation formulas to suit respective specialty chains.Calculation results of sprocket tooth profiles of mainsprockets are shown in the corresponding table onP117.The sprockets used for the following chains are thesame as the standard sprockets in tooth gap form, butdifferent in tooth thickness (sprocket tooth profile).

4. Calculation of sprocket dimensionsThe dimensions of standard sprockets and othergeneral sprockets are calculated as follows. At first, thediameters of sprockets are calculated from thefollowing calculation formulas. Calculation formulas oftooth gap forms are shown on P118.

Next, sprocket tooth profile (the shape of the toothdepending on its thickness) is calculated from thefollowing calculation formulas. (The values shown in thefollowing pages were calculated by these formulas andregarded as the standard values.)

Calculation formulas for diameters and tooth gap forms

Calculation formulas for diametersCalculation of pitch diameter, tip diameter and caliperdiameterThe basic dimensions of a sprocket suitable for a chainpitch of 1 mm are respectively called pitch diameterfactor, tip diameter factor and caliper diameter factor.The respective factors for respective numbers of teethare listed below. If these factors are multiplied by chainpitch, the basic dimensions of the correspondingsprocket can be obtained.

Example: In the case of DID80 (25.40 mm pitch) with 35 teethPitch diameter (Dp)

＝ P×Pitch diameter factor ＝ 25.40×11.1558≒283.36

Tip diameter (Do) ＝ P×Pitch diameter factor ＝ 25.40×11.711≒297

Root diameter (DB) ＝ Pitch diameter (Dp)－Roller diameter (Dr)＝ 283.36－15.88＝267.48

Caliper diameter factor (Dc) ＝ P×Caliper diameter factor－Roller diameter (Dr)＝ 25.40×11.1446－15.88≒267.19

Calculation formulas for tooth gap formsAs the most rational tooth gap forms in which thepressure angle changes in response to the elongation ofa smoothly rotated roller chain with the lapse of servicetime, ANSI specify two types of tooth profiles: U-type

and S-type. In general, S-type tooth profiles areadopted in accordance with ANSI, and our standardsprockets also have S-tooth profiles.

1. The description in this chapter can be applied when achain is endlessly engagedfor transmission with twosprockets parallel in theirshafts and accurate inalignment as illustratedbelow.

2. Consult us when a chain is to be used for lifting, pullingdollies or being engaged with a pin gear, etc.

3. When there are any regulations or guidelines concerningthe selection of chains, select a chain in accordancewith such regulations and the maximum kilowatt ratings(Drive performance) table described below, and choosethe one with a larger allowance.

The chain can be selected according to the following twomethods:(1) Selection by drive performance(2) Low-speed selection

The drive performance method considers not only chaintension but also the shock load on the bushings and rollersdue to the engagement between the sprockets and thechain, and the wear of pins, bushings and rollers.

The slow-speed method is applied when the chain isoperated at a speed of 50 rpm or less. In general, the chainselected by this method is subject to conditions moresevere than that selected according to the selection bydrive performance. Thus, carefully assess the conditionswhen selecting with this method.

Selection by drive performanceFirst, the following information is required.qPower to be transmitted (kW)wSpeeds of driving shaft and driven shaft (speed ratio)

and shaft diameterseCenter distance between driving shaft and driven shaft

(a) Correction of power to be transmitted (kW)Correction must be made to obtain the actual power to betransmitted as the level of load fluctuates depending onthe machine and power source used, affecting theexpected service life (for example, 15,000 hours in thecase of capacities shown in the table of maximumkilowatt ratings). The service factor shown in Table 1 is anindicator of the load level. The power to be transmitted(kW) is multiplied by the corresponding service factor toobtain a corrected power.

Corrected power (kW) ＝Power to be transmitted (kW) ×Service factor

(b) Selection of chain size and the number ofteeth of small sprocket

Use of simple selection chartThe number of teeth of small sprocket and the chain tobe used are tentatively decided with reference to thesimple selection chart (P122~P123) and the correctedpower (P120~P121).

Using the table of maximum kilowatt ratingsIf the results tentatively decided as described above areclose to the design values, the number of teeth of smallsprocket can be finalized with reference to the table ofmaximum kilowatt ratings. The maximum kilowatt ratingsare established anticipating that an endless chain with 100links has a life of 15,000 hours under the followingconditions. (That is, the breaking of the chain and the lossof bushings and rollers do not occur at a wear elongationof 2 percent or less.)qOperation is carried out in ambient temperature (-10°C~

+60°C) free from dust and dust-containing liquid.wThere is no corrosive gas, or humidity, etc. to adversely

affect the chain.eProper lubrication is maintained.rThe chain is used under conditions of a low start-stop

frequency and a fairly stable load.

In the case of multiplex chainSelect a multiplex chain when the capacity of a simplexchain is insufficient. The maximum kilowatt rating of amultiplex chain cannot be obtained by multiplying themaximum kilowatt rating of a simplex chain by thenumber of multiplex chain since the loads are notevenly distributed between the strands. For thecorrection factor in this case, see the multiplex chainfactor table. Our standard HI-PWR-S Roller Chains andHI-PWR-SHK Roller Chains are available up to triplex.

Remarks for determining the number of teethof small sprocketWhen a chain of the minimum chain pitch requiredmaximum kilowatt rating is selected, relatively silent andsmooth transmission can be achieved, and the equipmentcan be compact.However, considering smooth chain transmission, thewear of the chain and sprockets, etc., it is desirable thatthe sprocket have 15 or more teeth, and preferably anodd number. Avoid 12 teeth, 14 teeth and 16 teeth. Whenthe sprocket has 12 or less teeth, the chain and sprocketheavily vibrate and are extremely worn, and transmissionis not smooth. Likewise, avoid a small number of teeth asmuch as possible except in the case of low speed withoutshock.

Shaft diameterAfter the number of teeth of small sprocket is determined,multiply it by the speed ratio, and confirm whether therequired shaft bore can be secured in reference to themaximum shaft bore in the table of sprocket dimensions.If the required shaft bore is larger than the maximum shaftbore, increase the number of teeth, or choose a one sizelarger chain.

(c) Selection of the number of teeth of largesprocket

When the number of teeth of small sprocket is determined,multiply it by the speed ratio to determine the number ofteeth of large sprocket.In general, increasing the sprocket teeth number makesthe chain bending angle smaller, which increases durabilityand enhances transmission efficiency. However, if thenumber of teeth is too large, slight elongation tends tocause the chain to ride over the sprocket, so keep themaximum number of teeth at 114 or less.

Speed ratioA speed ratio refers to the ratio of the speed of the drivingshaft to the speed of the driven shaft, and usually a speedratio of 7:1 or less is safe. If the speed ratio is larger thanthis ratio, the take-up angle of the chain on the smallsprocket decreases, and chain jumping or abnormal wearof sprocket are likely to occur. If a large speed ratio isnecessary, two-step speed change may be necessary.

Low-speed selectionThe low-speed selection method is used when the chainoperation speed is 50 m/min or less and there is no worryof wear elongation and shock fracture of rollers andbushings.In low-speed selection, the chain is selected in referenceto the tensile fatigue strength of the chain. Therefore, achain selected according to this method will be subject tomore severe conditions than one selected according tothe selection by drive performance method. When theLow-speed selection method is used, special care mustbe exercised. The Low-speed selection method cannotbe used for the connecting links and offset links.

(a) How to obtain corrected chain tension

Corrected chain tension＝

（）×（service factor）

See Table 1 on the previous page.

To calculate the corrected chain tension, identify theexact maximum tension acting on the chain. The shock isconsidered to some extent in the service factor, but it isnot absolute. Also consider the increase of tension by theinertia of equipment caused by starting and stopping.

(b) Comparison with the maximum allowabletension of chain

Using the maximum allowable tension in the table ofchain dimensions, sprocket tooth factor and rotatingfactor of the small sprocket listed below, obtain thecorrected maximum allowable tension from the followingformula:

Corrected maximum allowable tension＝（Maximum allowable tension）×（Sprocket tooth factor）×（Rotating factor）

If the corrected maximum allowable tension is larger thanthe corrected chain tension, you can select the chain.For the number of teeth and speed of small sprocket notstated in Table 1 or 2, obtain the sprocket tooth factorand rotating factor by linear interpolation.

See the table of chain dimensions See Table 1. See Table 2.

Chain Selection by TemperatureThis is a chain selection method taking deterioration of strength in relation to temperature into consideration. Pleaseuse appropriate lubricant for the temperature at which the chain is to be used. Consult us for details.

1. Effects of temperature on the chains1.1 Effects of high temperature

1) Increased wear caused by decrease in hardness2) Increased elongation caused by softening3) Lubricant degradation, defective flexion caused by

carbonization4) Increase in wear and defective flexion caused by

development of scales

2. Kilowatt ratings according to temperature

※Please be aware that ambient temperature and the temperature of chains may differ.

3. Chain Selection according to TemperatureSee slow-speed selection (p121) for use at extreme temperatures other than normal temperature.(Chain speed=50m/min or less)

4. Use of Stainless Steel Chains (SS, SSK) at high temperaturesStainless steel chains (SS, SSK) can be used up to 400°C, but be aware that the ambient temperature and the chaintemperature may differ. The strength of the chain decreases as the temperature rises. Especially at hightemperatures, the higher the temperature rises, the chain will rupture by a lower load (creep rupture).In addition, defective flexion or defective chain revolution occurs due to heat expansion. In order to prevent suchproblems, adjust the clearance between chains. Consult us when using chains at 400°C or higher.Chains cannot be used at 700°C or higher.

1.2 Effects of low temperature1) Decrease in resistance to shock caused by low

temperature brittleness.2) Defective flexion caused by lubrication oil coagulation.3) Defective flexion caused by adhesion of frost and ice.4) Rusting caused by water-drops.

Chain Length and Sprocket Center Distance

Required length of roller chainUsing the center distance between the sprocket shaftsand the number of teeth of both sprockets, the chainlength (pitch number) can be obtained from thefollowing formula:

Lp＝N1＋ N2

2＋ 2 Cp＋｛（ N2－N1 ）／2π｝2

Cp

Lp : Overall length of chain (Pitch number)N1 : Number of teeth of small sprocketN2 : Number of teeth of large sprocketCp: Center distance between two sprocket shafts (Chain

pitch)

｛（N2－N1）／2π｝2 can be obtained from the following table.

The Lp (pitch number) obtained from the above formulahardly becomes an integer, and usually includes adecimal fraction. Round up the decimal to an integer.Use an offset link if the number is odd, but select aneven number as much as possible.When Lp is determined, re-calculate the center distancebetween the driving shaft and driven shaft as describedin the following paragraph. If the sprocket centerdistance cannot be altered, tighten the chain using anidler or chain tightener shown on P.126.

Center distance between drivingand driven shaftsObviously, the center distance between the driving anddriven shafts must be more than the sum of the radius ofboth sprockets, but in general, a proper sprocket centerdistance is considered to be 30 to 50 times the chain pitch.However, if the load is pulsating, 20 times or less is proper.The take-up angle between the small sprocket and thechain must be 120°or more. If the rollerchain length Lp isgiven, the centerdistance betweenthe sprockets can beobtained from thefollowing formula:

Cp＝ {Lp－　　　　　（Lp－　　　）2－　（N2－N1）2 }Cp : Sprocket center distance (pitch number)Lp : Overall length of chain (pitch number)N1 : Number of teeth of small sprocketN2 : Number of teeth of large sprocket

Layout

When the chain layout is undesirable:¡When the top is sagging and the sprocket center

distance is short:As illustrated below, adjust the sprocket center distanceshaft to eliminate the sag.

¡When the top is sagging and the sprocket centerdistance is long:As illustrated below, install an idler from inside toeliminate the sag.

¡When the chain is vertical or inclined:As illustrated below, eliminate the extra sag by atensioner. In this case, a tensioner that automaticallyeliminates the sag gives better results.

When a pulsating load acts in highspeed operation:The chain's vibration and the load impact frequency orchordal action may synchronize to amplify vibration onthe chain. Since vibration affects the chain, takecountermeasures to prevent vibration in the followingmeasures:¡Change the chain speed.¡Increase chain tension. However, note that over-

tensioning can shorten the life of the chain.¡Use an idler or tensioner to divide the span.

¡Install a guide stopper to prevent vibration.

When a roller chain is used, shaft positions can be arbitrarily determined. However, in principle, follow the illustrationshown below. That is, if the chain is tensioned horizontally, keep the top tensioned. Avoid vertical transmissionwhenever possible.

Installation

Installation of sprocketsFor smooth transmission and extended life of the rollerchain, it is important to correctly install proper sprockets.Use the following installation procedure.

1. Properly install a sprocket on a shaft, and fix it with akey to prevent it from rattling during operation. Also,place the sprocket as close as possible to the bearing.

2. Adjust the shaft levelness to ±1/300 or less using alevel.

3. Adjust the shaft parallelism（）to ±1/300 or less.

4. Adjust the level of driving and driven sprockets usinga linear scale. (Also adjust the idler and the sprockets,or the tensioner and the sprockets in the same way.)

Keep the allowance δ in the range specified below.

Installation of roller chainWhen connecting a roller chain with the sprockets,observe the following procedure. When the connectinglink is not well lubricated, apply sufficient grease.

When using the sprocket teeth1. Engage the chain with the sprockets so that both

ends of the chain are on one of the sprockets, asshown in the following photo.

2. Insert connecting pins at the joint.3. Fit a connecting plate, and fasten by a spring clip or

cotters.

Pay extra attention not to damage the tooth heads ofthe sprocket.

When using toolsCautions1. When a connecting plate is fastened by a spring clip,

apply the spring clip to the pin grooves of theconnecting pins as illustrated below, and lock it usingpliers, etc. As for the direction of spring clip insertion,keep the opening of the spring clip turned in thedirection opposite to the direction of chain rotation, asillustrated below.

2. In circumstances where the sprocket center distancecan hardly be adjusted, an odd number of links may beused. However, add one link, to use an even number oflinks and eliminate the sag by shifting a sprocket orinstalling an idler.

3. When an H-connecting link is used, pins must be driveninto the connecting plate because of interference. Inthis case, ensure that the pair of pins are kept parallelto each other when inserted into the connecting plate.Never make the holes of the connecting plate larger ormake the pins thinner for easier connection work. Thisapplies also when a cotter type outer link (CP) is usedinstead of a connecting link.

How to connect O-ring Chains

Remarks to connect general O-ring Chains:

1. A connecting link of an O-ring Chain for generalapplication is pre-coated with grease at the pins. Beforeconnection, confirm the grease on the surfaces of pins,and if the amount of grease is small, apply grease withbare hands. (If gloves are used, the grease will beabsorbed by the gloves.)Example: When the connecting link (I) of an O-ring chainfor general application isshipped, O-rings are fittedat the roots of the pins. Ifthe O-rings come loosedue to vibration duringtransport, refit the O-ringsin to the roots of the pins.In this case, be sure to return the grease collected at theroots of the pins to the central surfaces of the pins, moreat portion A than at portions B shown in the aboveillustration. (Portions A is worn because of sliding withthe bushings.)

2. The chain can be most easily connected on the teethof a sprocket. Engage the links at both ends of thechain with the sprocket teeth and fit connecting pins.If the sprocket can be moved, the chain can also beconnected on the loosened side.

3. Connecting procedureqConfirm that O-rings are attached to the roots of

the pins.wIf the amount of grease applied on the connecting

pins is small, coat the pins with grease at thecentral portions.

eInsert the connecting pins into the bushings of theinner links at both ends.

rConfirm that the grease is applied to the entire faceof the O-ring, and fit the O-ring onto the connectingpins.

tInsert the connecting pins into the connecting plateand while pressing the connecting plate, install thespring clip. Confirm whether the head (the endwithout a split) of the spring clip is turned in thefeeding direction of the chain. (See the followingillustration.)

yBe sure to confirm that the spring clip is securelyfitted in the clip grooves of the connecting pins.

This completes jointing of the connecting link. Note thatgrease on the surfaces of connecting pins and O-ringscan be removed during installation work. In this case,re-grease using the grease on the surface of the basechain or the grease in the polyethylene bag in which theconnecting link was contained.

Checka. Confirm the following before operation

b.After confirmation and adjustment of the above a,install the safety cover, and switch on the power tostart operation.¡It is possible for the chain to be thrown should it break.

Do not stay in the direction of rotation during operation.

Before trial operationConfirm the following on chain installation beforestarting operation.¡The chain correctly engages with the sprockets.¡The joints are normal. (The spring clips are correctly

installed and cotters are not bent.)¡The chain sag is proper.¡The chain is not in contact with the chain case.¡The lubrication is proper.

Check items during trial operationIf the chain can be manually rotated, rotate it to confirmthat there is no abnormality before starting trial operation.Be alert to the following during trial operation.¡Whether there is abnormal noise.

If the chain contacts the chain case or if the chain heavilyvibrates, abnormal noise occurs. Check the installation ofchain case and chain sag.

¡Whether lubrication is normal during operation.Re-check the condition of lubrication.

Elongation limit of chainLimit of Chain Sag¡Events caused by sag failureEven if the sag of the chain is normal before the start ofoperation, it can increase if the chain is elongated due to

wear of pins, bushings, etc. If the sag is excessive, thefollowing will occur.a. Abnormal vibrationb. Chain rollers ride over the heads of sprocket teeth.c. The chain is seized by a sprocket.d. The chain contacts the chain case.These conditions can often cause abnormal noise. Shouldany abnormal noise occur, immediately stop operation,and check carefully to determine the cause. Suchconditions often cause damage not only to the chains, butto the entire equipment. A preliminary check is necessary.¡Elongation limit of chainEven if sag adjustment is normal, excessive elongation ofthe chain can cause abnormalities similar to those causedby sag failure that inhibit smooth transmission. In suchcases, replace the chain. A guide for replacement basedon chain elongation limit is listed below. Even if only onelink reaches the elongation limit, replace the entire chainwith a new one. Unless lubrication is normal, the chain willelongate quickly, causing the aforementioned troubles.Read the contents of "Lubrication" in the next sectioncarefully for performing proper maintenance.

¡Elongation measuring method1. To eliminate rattling other than a slight amount of play

in the chain as a whole, tighten the chain lightly andmeasure the elongation.

Note: For an accurate measurement, measure the elongation of the chainapplying a measuring load (specified by ANSI) to the chain.

2. As illustrated below, measure the inner length (L1) andthe outer length (L2) and obtain the measured length (L).

3. Then, obtain chain elongation.

Reference length = Chain pitch × Number of links

4. In order to reduce the measuring gap, measure thelength of about six to ten links.

Chain wear-elongation check gageWe recommend and can supply a chain wear-elongationcheck gage (P.114) for facilitated finding of elongation limit.

Maintenance

¡Obstacles may cause breaking or fracturing which canscatter materials and injure people nearby. Be sure toremove all obstacles.

¡Abnormal noise during operation is a sign of trouble.Immediately switch off the power, and determine the cause.

¡If any serious flaws or rust is visible, it may cause the chainto break and fracture and possibly injure people nearby.Confirm that the chain has no serious flaws or rust.

¡If a sprocket is worn, the sprocket may break, or the chainmay ride over the sprocket, breaking it and possiblyresulting in injury to people nearby. Confirm that thesprockets are not worn.

¡Install accident prevention devices.To avoid human injury caused by scattered materials,install safety devices (safety cover, safety net, etc.).

¡Install an emergency stop device.To avoid human injury due to unexpected overload, installan emergency shutdown device such as a load controlleror a brake.

Sag adjustment of roller chainTo use a roller chain for a longer period of time, propersag is an important component. If the roller chain is over-tensioned, the oil film between pins and bushings is lost,shortening chain life and damaging the bearings. If thechain sags overly, the chain will vibrate or be seized bythe sprocket. In about 50 hours (it differs depending onthe service conditions) after starting the roller chain use,the chain will be elongated by about 0.1 percent of theentire length due to the conformability of respectivecontacts. So, adjust the sag at this time. Thereafter, ifproper lubrication is maintained, the elongation will benegligible. Check and adjust the sag at proper intervals.

Optimum sagIn general, keep sag S at about 2 % of span L, but inthe case described below, keep it at about 1 %.

Keep sag at 0.01L or less in the following cases:™When the chain is installed vertically or almost

vertically.™When the chain is installed horizontally or almost

horizontally with the top slackened.™When the center distance between sprockets

exceeds 50 times the chain pitch.™When vibration or shock occurs.™When the chain is frequently started and stopped.™When the chain is suddenly reversed.™When the speed ratio is 7:1 or more (keeping the

speed ratio at 7:1 or less is safer and preferable).）

How to adjust sagAdjust sag in the following ways.

1. Adjustment of the center distance

2. Adjustment using a tensioner or idler

3. Increase or decrease of pitch number by offset link

By using an offset link, the total length of a chain canbe increased or decreased by one pitch. However,since offset link performance is generally poor, an evennumber of links, if possible, is recommended.

Other checks¡Checking sprocketIf a sprocket is not installed at the correct position of theshaft or is not parallel to the shaft, the plates of the chainmay be flawed, or the chain may be twisted. This can bejudged by examining the contactfaces of the sprocket teeth. In thisillustration, a uniform contact asindicated by A is normal. If thecontact is different on both sidesas indicated by B, correction isnecessary.¡Checking idler or tensionerWhen sag is adjusted, check also whether the idler ortensioner itself is damaged. If the contact between an idleror tensioner and a chain is at the center of the tooth gapbottom as indicated by C, it is normal. If the contact is asindicated by A or B, the bearing of the idler or tensionermay be abnormal.¡Checking chain attachmentsIn the case of a chain with attachments, it can result inaccidents if a mounted part is loosely installed or comesoff. Furthermore, if an installation hole is enlarged due towear, the chain life may be shortened.

Necessity of lubricationIn a roller chain transmission, even if the chain andsprockets are designed to suit the service conditions,poor lubrication inhibits maintaining performance and lifeto design specifications. In the case of a roller chain, thewear loss caused under proper lubrication is dramaticallydifferent from that caused without it. Troubles caused dueto insufficient lubrication include the wear of pins andbushings, rough engagement with the sprockets,increased noise, and breakage as a result of prolongedundesirable conditions. Proper lubrication is veryimportant. Requirements of lubrication and the effects ofproper lubrication are listed below.

Selection of lubricantSelect the lubricant of a roller chain in reference to thelubrication type (P.133), ambient temperature and chainNo., according to the following table.Lubricant should be a mineral oil of good quality. It isimportant that the lubricant contains no dust or foreignsubstance. Never use waste oil. If the ambienttemperature is extremely low (-10°C or lower) or high(+60°C or higher), a specific oil is necessary. In this case,please consult our engineering department.

Lubricating pointsIf the chain is immersed in an oil bath, oil penetrates everypart of the chain. In the case of manual lubrication, brushlubrication or drip lubrication, ensure that the oilsufficiently penetrates the portions of q and w in thefollowing illustration.

Lubricate on the sag side of the chain, i.e., at the positionindicated in the following illustration. Since the lubricantis also useful for rust prevention, coating the entiresurface of the chain with the oil is recommended.

Name and method Lubrication intervals and amount

Carry out periodical usinga lubricator or brush atleast once a day.

While rotating the chainslowly, lubricate the entirelength uniformly three tofour times. Take care notto allow your hand orclothes to be caught by thechain during lubrication.Note that extra oil will bescattered when theoperation is started.

In this case, since extraoil is scattered, installinga simple casing isrecommended.

The container should beleak proof. Before usingthe container for the firsttime, thoroughly wash theinside to remove dust andother foreign substance.

The oil container shouldbe leak proof. When usingthe container for the firsttime, thoroughly wash theinside to remove all dustand foreign substance.

Supply about 5 to 20drops of oil per minute.

Keep the chain immersedin oil, about 10 mm belowthe oil surface. If immersionis too deep, the oil willbecome abnormally hot.

A disk is used to apply oilto the chain. Keep the diskimmersed in oil, at a depthof about 20 mm. Keep theperipheral speed higherthan 200 m/ min.

The amount of lubricationmust be set to avoidabnormal heating. Ingeneral, the oil amountshould be set at a levelnot to allow the chain hightemperature over 60°C.

General cautions for lubricationUnless proper lubrication is carried out, chain fatigue willresult earlier, causing various problems. Carefulinspection is necessary.

If the lubricant is exhausted, red rust is generated betweenthe inner and outer plates, causing wear drastically. When achain is disassembled after going under such condition, redrust is visible on the surfacesof pins, and the surfaces areroughened, as shown in thisphoto. (Normally, pins have amirror surface.) The lubricantmust be applied before thishappens.

Do not use grease to lubricate your chains, since greasetakes too long to reach the inside through pins andbushings at ambient temperature. Use the machine oilshown in the table on P.132 or DID Chain Lube/DID HI-PWR Lube (a spray lubricant).

Before lubrication, remove foreign substances and dirtfrom the chain as thoroughly as possible. If water is usedfor washing the chain, quickly dry it to prevent rusting,and then lubricate.

Check the following:1. The lubricant is not dirty.2. The amount of lubricant is correct.3. Lubricant is uniformly applied to the chain.

Dust contamination must be avoided to maintain wearresistance. If temperature rises abnormally or the chainsqueaks, the oil may be exhausted. Check to verify thecondition.

In the case of insufficient lubrication

Do not use grease for lubrication !!

Cautions

In the case of drip lubrication, oil bath lubrication or forced feed lubrication

Trouble

A pin, bushingor roller isfractured.

Note: See"Fracture patternsof respective chaincomponents" onP.136.

Abnormal noise

Possible cause

High speed revolution exceeding thetolerance of chain and sprockets

Sudden large shock load

Improper lubrication

Corrosion of chain

Wear of sprocket

Seized foreign substances

Chain is excessively tensioned orsagged.

Incorrect alignment of sprockets

Large wear elongation of chain or wearof sprocket

Incorrect installation of chain case

Improper lubrication

Improper combination of chain andsprockets

Decelerate the speed, or select a chain with a smaller pitch. Otherwise, select asprocket with a larger number of teeth. Refer to the details of "Selection byDrive Performance (kilowatt ratings)" (P.120).

Avoid shock load as much as possible. Install a damper, etc., to damp the shock load.

Periodically supply the correct lubricant. Spray type chain oil "DID Chain Lube"is recommended.

Check the service circumstances and lubrication condition, and select a proper chain.

Replace it with a new one. Use a sprocket conforming to the correct standarddimensions.

Immediately remove the foreign substances, and strictly control the service circumstances.

Pay constant attention to the chain sag. Correct by adjusting it according to theprocedure stated in "Sag adjustment of roller chain" (P.131).

Check the alignment between both the large and small sprockets.

Replace chains that are elongated beyond the tolerance and worn sprocketswith new ones.

If the chain contacts the chain case, immediately correct and adjust.

Lubricate properly and periodically. (See "Lubrication types" (P.133).

When replacing the chain, use the correct chain size and sprocket sizes. Selecta chain suitable for sprocket sizes, and sprockets suitable for the chain size.(Especially be alert when replacing HK Series multiplex chain.)

Interference of foreign substances

Excessive tensionRiding of chain over sprocketCorrosion of chain and improper lubrication

Replace the excessively worn chain with a new one.

A chain with too much slack causes the chain to ride over a sprocket, and candamage the tooth heads of a sprocket. Correctly adjust it.

Replace the worn sprocket with a new one. If foreign substances are depositedon the bottoms of the teeth, immediately remove them.

Misalignment of large and small sprockets result in abnormal wear of the sidesof link plates and the sprockets, thereby shortening chain life. Apply a straightedge to the lateral sides of sprockets to check alignment.

Adjust to a proper sag. Consider the installation of spring type idler or tensioner.

Imperfect and uneven lubrication causes uneven wear and pitch irregularity.Immediately replace the chain, and lubricate the entire chain evenly.

See the following column.

Select a DID chain with a larger allowable tension.

If the alignment between sprockets is incorrect, the force applied from the sidesof the sprockets opens the inner plates, which interferes with the outer platesand cause stiff links. Align the large and small sprockets properly.

If a chain is left without lubrication for a long time or in a corrosive atmosphere,rust is generated and smooth motion is inhibited. A corroded chain must bereplaced. Be sure to lubricate periodically.

If a chain comes in contact with foreign substances during feeding, the innerand outer plates may be opened. Immediately remove the foreign substance.

If sand or mud enters bending sections, remove the chain, and wash andlubricate, or replace the chain. Furthermore, install a case, etc. to prevent theingress of sand and mud.

If a chain is used for a long time at a load exceeding the maximum allowabletension, fatigue fracture of plates and bending fatigue fracture of pins occur. Ifthe chain life before fatigue fracture is shorter than the expected life, select achain with a larger maximum allowable tension. For example, if a DID50Standard Roller Chain is used for 750 cc motor-cycles, it may be fractured in ashort time. In this case, rather than the chain being faulty, the selection wasincorrect.

If a load or impact extremely larger than the allowable tension acts on a chain,ductile fracture of plates or fracture of pins by shear or bending occurs. Thisfracture occurs when the chain size selected is incorrect and allowable tensionis too small. Re-select a proper chain.

The fracture caused when the chain rides over a sprocket is mainly caused bywear elongation. Select an appropriate chain, and lubricate properly.

Remember that a chain might be broken suddenly by hydrogen embrittlement ifit comes in contact with acids.

If foreign substances interfere with or are seized by the chain during feeding,excessive load acts on the chain, and its life will be shortened or it may breaksuddenly. Make necessary arrangements for an appropriate servicecircumstances, and be sure to immediately remove any foreign substances.

If excessive tension is the cause, select a chain larger in allowable tension.See the column "When the chain rides over a sprocket".See the third frame of "Stiff link".

Fracture patterns of respective chaincomponentsTo be aware aforetime of how and which part of the chainis damaged under improper use greatly helps to clarify thecause and determine corrective measures in such anevent.

¡Fracture of plate.When a large tensionacts to fracture a plate,as shown in (a), the cutends are oblique andplastic deformationoccurs. However, whenthe load is slightly largerthan the maximumallowable tension, fatiguefracture occurs, and anyplastic deformation doesnot occur as shown in(b). A significant feature of fatigue fracture is that a crackoccurs in the direction almost perpendicular to the pitch line(center line between both pins). In the case of hydrogenembrittlement by an acid, the crack mostly occurs in thedirection as shown in (c), and the cut ends are flat, while thearea around the cut ends may be decolored due to erosionby the acid.

¡Fracture of pinsWhen a pin is fractured byexcessive tension, thefracture occurs close to theplate, with a bulged specularsurface formed by shearing,as shown in (d). However,when the acting force is notso strong, fatigue fracturetakes place after a longperiod of time around thecenter of the pin as shown in (e), and the fractured surfaceis flat with small undulations.

¡Fracture of bushingsAs with rollers, bushings fracture byshock. Generally, as shown in thephoto, a vertical crack occurs andstops near the plates. One crackcan also be superimposed onanother, causing the central portionto come off. In general, it can besaid that a larger crack is caused bya larger tension.

¡Fracture of rollers

When a roller fractures during operation, typically verticalsplitting occurs as shown in the photo, and in general,pitch marks of fatigue extend from the inside of the rollerand cause splitting. If splitting occurs all at once due to alarge tension, the cause can be identified easily since thesplit faces are not polished. If tension is excessive, therollers are forcefully pressed against the tooth faces ofsprockets, and a roller end may be cracked anddeformed.

¡Rotation of pinsAs shown in the photo, the rotationof a pin can be identified by thedeviance of the rivet mark on the pinhead from the correct position. If thechain is disassembled, galling isfound between pins and bushings inmost cases. The cause of galling isimproper lubrication or excessivetension. When a machine has beenout of use for a long period of time, rust may developbetween pins and bushings, causing the pin to rotate.

Elongation of chainIn general, the elongation of chains includes thefollowing three types;

1. Elastic elongation by chain tensionIf a load acts on a chain, the respective components ofthe chain are elastically deformed, causing elongation. Ifthe load is removed, the original length is restored.

2. Plastic elongation by chain tensionIf a load in excess of the elastic limit acts on a chain,plastic elongation occurs. In this case, even if the load isremoved, the original length cannot be restored. Plasticelongation of chain may diminish its performance.Replace it without delay.

3. Wear elongation of chainChains are subject to wear since pins and bushings areworn by mutual contact. After use for a long time, thewear appears as an increase of chain length. This is wearelongation. Wear elongation is an important factor fordeciding the timing of chain replacement. See P.137.

Timing for ReplacementIf the engagement between chain and sprockets becomesdefective or any factor that causes excessive decline in thestrength of the chain occurs, replace the entire chain.When any of the following conditions occur in the chainyou use, replace the entire chain to maintain safety.

¡When a chain is worn close to the "Elongation limit ofchain" on P.130.

¡When a flaw or crack occurs in a plate.¡When a flaw or crack or defective rotation of a roller is

observed.¡When a chain link is stiff.¡When a pin has been rotated.¡When a pin is bent or otherwise deformed or when a

plate is seriously warped.¡When rust buildup prevents smooth bending of the

chain.¡When diluted sulfuric acid or any other corrosive

material is deposited.※If you cannot judge whether a flaw is "harmful", please

consult us.

Replacement of sprockets and how to orderThe life of sprockets is generally several times the life ofa chain, but if the teeth are worn because of insufficientlubrication or damaged because of a shock load, etc.,the sprockets must be replaced.™When placing an order, please specify the following if

the chain No. is known.1. Chain No. and number of strands2. Type of sprockets3. Shaft hole diameter (d) (This is not necessary if you drill

this hole; in this case, drill a hole not exceeding themaximum shaft hole diameter.)

4. Number of teeth5. Hub diameter (DH) and length (L) (in the case of non-

standard sprockets)6. Whether the tooth heads are hardened™Specify the following items, if the chain No. is unknown1. Tooth thickness (T)2. Root diameter (DB) (Caliper diameter (DC) in the case

of odd-number teeth)

Small Conveyor Chains General

Ultimate Life Chain Series and Environment Resistant Chain Series described in the previous chapter are also availablefor Small Conveyor Chains, which are listed on P142-143 for reference.

The main components of DID Small Conveyor Chain consists of two basic types single pitch chains and double pitchchains.Single pitch chains correspond to "General application chains" in the previous chapter of "Roller Chains for PowerTransmission", and are used with ANSI standard sprockets". Double pitch chains are standardized as ANSI DoublePitch Chains, and the design of pins, bushings and rollers are basically the same as that of single pitch chains. Theplates only are made longer to double the pitch of single pitch chains. The sprockets of double pitch roller are alsostandardized as ANSI double pitch chain sprockets. Small Conveyor Chain is mainly composed of the above basechains, and is attached with various top rollers, side rollers or attachments that customize chains for differentapplications. Classifications of DID Small Chains for Conveyor Systems are shown on P141.

How to indicate the specially arranged chains with attachments

A chain with Attachment K1s specially arranged asabove is indicated as follows:

CJ＋（K1 inner＋PL）×3＋3LL＋PL＋（K1 inner＋PL）×3＋3LL＋K1 outer＋（RL＋K1 outer）×2＋5LL

Consult us for other arrangements that cannot be indicated as above.Note: When attaching attachments to every even-number link, they are

attached to outer links, unless specified.

"CJ" stands for a C connecting link; "K1 inner", an innerlink Attachment K1; "PL", an outer link; "3LL", three linksfrom an inner link to an inner link; "K1 outer", an outerlink Attachment K1; and "RL", an inner link, respectively.A "＋" sign means "connection", and a "×" sign means"repeat". (For one-side attachments such as AttachmentA and Attachment SA, the position of attachment platesis on side A in the above illustration.)
