Standard Type Cam FollowersThese are the basic type bearings in CamFollower series. Models with stud diameters rangingfrom 3 to 30 mm are prepared, and are suitable for awide range of applications.

Solid Eccentric Stud Type Cam FollowersThe stud of these bearings is eccentric to the centeraxis of the outer ring. Thus, the position of the outerring in the radial direction in relation to the matingtrack surface can easily be adjusted by turning thestud, and the load distribution on a number of camfollower outer rings used on the same track surfacecan be made uniform. These are eccentric cam followers with a one-piecestud that can be mounted in the same mounting holesas those for Standard Type Cam Followers.Eccentricity is 0.25 mm~0.6 mm.

Eccentric Type Cam FollowersIn these bearings, an eccentric collar is assembledwith the Cam Follower stud, enabling the outer ring tobe positioned easily in the radial direction against themating track surface.Eccentricity is 0.4~1.5 mm.

Thrust Disk Type Cam FollowersThese bearings have special resin thrust disk wash-ers superior in wear and heat resistance between thesliding surfaces of outer ring shoulders, stud headand side plate. These disk washers reduce frictionand wear due to axial loads caused by misalignment,etc.

Centralized Lubrication Type Cam FollowersThese bearings have one or two pipe-threaded holesin the stud. Thus, this series is suitable when central-ized lubrication is required.

Easy Mounting Type Cam FollowersThese bearings have a stepped tapered portion onthe stud. When mounting the Cam Follower, it is easyto fix its location by tightening a set screw to thestepped portion. Thus, this type is suitable when alarge number of Cam Followers are used in amachine such as a pallet changer.

C-Lube Cam FollowerThese bearings are lubricated with a newly developedthermosetting solid-type lubricant which fills the innerspace of the bearing. This lubricant provides long-term maintenance free.

Cylindrical Roller Cam FollowersThese bearings are full complement type bearingsincorporating double rows of full complement cylindri-cal rollers in the outer ring, and can withstand largeradial loads and some axial loads.

Miniature Type Cam FollowersThese are compactly designed bearings, incorporat-ing very thin needle rollers in an outer ring with asmall outside diameter. They are used in electronicdevices, OA equipment, small index devices, etc.

《Shield type》 《 Sealed type》

《Crowned outer ring》 《Cylindrical outer ring》

《With screwdriver slot》《With hexagon hole》

Roller guide methodCam Followers include the caged type and the fullcomplement type . The caged type has a small coeffi-cient of friction and is suitable for high speed rota-tions, while the full complement type is suitable forheavy loads at low speed rotations.

Seal structureCam Followers include the shield type and the sealedtype. In the shield type, the narrow clearancesbetween the outer ring and the stud flange andbetween the outer ring and the side plate formlabyrinths .The sealed type incorporates seals in the narrowclearances to prevent the penetration of foreign parti-cles.

Shape of outer ring outside surfaceThe outside surface of the outer ring of CamFollowers, which makes direct contact with the mat-ing track surface, is either crowned or cylindrical. Thecrowned outer rings are effective in moderating theedge load due to mounting errors. The cylindricalouter rings have a large contact area with the matingtrack surface, and are suitable for applications inwhich the applied load is large or the track surfacehardness is low.

Shape of stud headCam Followers are available in two stud head shapetypes, namely, the type with screwdriver slot and thetype with hexagon hole for hexagon bar wrench.

Various types are lined up in Cam Follower series,including the caged type, full complement type, shieldtype, sealed type, type with crowned outer ring, type

with cylindrical outer ring, type with hexagonal hole,etc.

the Cam Follower makes contact with the matingtrack surface (plane). The track capacities shown inTables 7.1 and 7.2 are applicable when the hardnessof the mating track surface is 40HRC (Tensilestrength 1250N/mm2). When the hardness of the mat-ing track surface differs from 40HRC, the track capac-ity is obtained by multiplying the value by the trackcapacity factor shown in Table 8.If lubrication between the outer ring and the matingtrack surface is insufficient, seizure and/or wear mayoccur depending on the application. Therefore, atten-tion must be paid to lubrication and surface rough-ness of the mating track especially for high-speedrotations such as cam mechanisms.For lubrication between the outer ring and the matingtrack surface, C-Lube Unit for Cam Followers is rec-ommended.

■Operating Temperature RangeThe operating temperature range for CamFollowers is -20 C゚~+120 C゚. However, the maxi-mum allowable temperature for the following types isdifferent.

The maximum allowable temperature for the MetricCF series with a stud diameter d1 of 4 mm or less,Stainless steel mede Cam Followers with a studdiameter d1 of 5 mm and CFS2 is +110 C゚, and +100C゚ when they are continuously operated.

The maximum allowable temperature for the sealedtype with a stud diameter d1 of 5 mm or less is +80 C゚.

Allowable temperature range of C-Lube CamFollowers is -15 C゚~+80 C゚. For a long term opera-tion, less than +60 C゚ is recomended.

■Mounting1 Make the center axis of the mounting hole perpen-

dicular to the moving direction of the Cam Followerand match the side shoulder accurately with theseating surface indicated by dimension f in thetable of dimensions. (See Fig. 1.) Then, fix theCam Follower with the nut. Do not hit the flangehead of the Cam Follower directly with a hammer,etc. This may lead to a bearing failure such asirregular rotation or cracking.

2 The mark on the flange head of the stud indi-cates the position of the oil hole on the raceway.Avoid locating the oil hole within the loading zone.This may lead to a short bearing life. (See Fig. 2.)The hole located in the middle part of the stud per-pendicular to the stud center axis is used for greas-ing or locking.

3 When tightening the nut, the tightening torqueshould not exceed the values shown in the table ofdimensions . If the tightening torque is too large, itis possible that the threaded portion of the stud willbe broken. When there is a possibility of loosening,a special nut such as a lock nut, spring washer, orself-locking nut should be used.

Fig. 2 Oil hole position and loading direction

Fig. 3 Mounting example of Solid Eccentric Stud Type Cam Follower

4 In the case of Solid Eccentric Stud Type CamFollowers and Eccentric Type Cam Followers, theouter ring position can be adjusted appropriately byturning the stud with a screwdriver or hexagon barwrench using the screwdriver slot or hexagon holeof the stud head. The stud is fixed with a nut and aspring washer, etc. The tightening torque shouldnot exceed the values of maximum tighteningtorque shown in the table of dimensions.When shock loads are applied and the adjustedeccentricity has to be ensured, it is recommendedto make holes in the housing, stud and eccentriccollar, and fix the stud with a dowel pin as shown inFig. 3. However, when the stud diameter is lessthan 8 mm (Eccentric collar diameter 11 mm), it isdifficult to make a hole in the stud because the studis through-hardened.

Option Parts

C-Lube Unit for Cam FollowersC-Lube Unit CL is the lubrication-supporting equip-ment for the track surface and Cam Follower's outerring to keep both surfaces free of maintenance.

Capillary system has developed is a new typelubrication. It is a porous resin Lube-body or platewith steel backing formed by sintering fine resin pow-der and impregnating a large amount of lubrication oil

in its open pores. Capillary system always suppliesproper amount of lubrication oil to the cylindricalrollers and lubrication condition of the raceway can bekept well for long period of time.

Also it prevents oil scattering causing pollution to thesurrounding environment, and helps minimizing oilconsumption.

■ Identification numberThe identification number example of C-LubeUnit is shown below.

■Allowable rotation speedThe rotation speed of Cam Follower with C-LubeUnit should not exceeded d1n=10,000 for reference.

d1n=d1×nd : Stud diameter of Cam Follower, mmn : Rotational speed, rpm

■Minimum rotational angleLubricating oil is supplied to the whole external diametersurface of the outer ring. Accordingly, use the productin a condition in which the outer ring makes one or moreturns.

■Operating temperatureAllowable operating temperature range of CamFollower with C-Lube Unit is -15 to 80˚C.

■Mounting1 Set the C-Lube Unit perpendicularly to the center

axis of Cam Follower and fix together with CamFollower by tightening nut.

■For use1 The maximum allowable load on Cam

Follower with C-Lube Unit is, in some cases, limitedby the bending strength and shear strength of theC-Lube Unit instead of the load rating of needlebearing part. In order to safety operation, the maxi-mum allowable static load is specified by the limita-tions of those strengths.

2 After assemling C-Lube Unit and Cam Followers inthe machine, please confirm that C-Lube unit pro-vides oil correctly to the track surface before actualoperation.

3 Do not use in the environment which contaminationof liquid and/or harmful foreign matter are expect-ed.

4 Do not wash with organic solvent and/or whitekerosene, which have the ability of removing fat norleave them in contact with the above agents.

5 To ensure normal rotation of the Cam Follower,apply a load of 1% or over of the dynamic load rat-ing at use.

6 Replace with new C-Lube Unit when inside oil fin-ishes completely. Re-lubrication is not possible.

7 Do not apply a load onto the C-Lube Unit directly.

Load

2 Position of C-Lube Unit is adjustable. C-Lube Unitmust be positioned avoiding loading direction.

3 When tightening the nut, the tightening torqueshould not be exceeded the value maximum tight-ening torque on dimension table. In case looseningof the nut is predicted due to vibration, using locknut, spring washer and other special washer arerecommended.
