eim rod ends and spherical plainbearings are intended for linkage applica-tions where a bearing must accommodatesignificant misalignment. While sphericalplain bearings offer flexibility in housingand mounting design, the user bears theresponsibility for housing design and thecost of housing manufacture. Rod endsoffer greater mounting convenience andprovide a compact, lightweight, economicaldesign alternative to the spherical plainbearing. Heim Bearings Company offersthe industry’s widest selection of rod endtypes and sizes.
Rod End ConstructionHeim offers three basic rod end construc-tions. The four piece rod end uses raceinserts, typically of brass, to providelubricity in the bearing area. This designoffers reduced internal clearance, andprovides smoother operation. It is ideal fordynamic applications. The two piece rodend uses a rod end body which is formedaround a spherical ball. The comparativelyheavy cross section of the rod end body inthe two piece design provides highstrength. This makes the two piece rod endideal for highly loaded, static applicationswhere high strength is required. Thecartridge type rod end consists of aspherical plain bearing mounted in a rodend body. This design allows the optimumselection of materials for ball, race and rodend body. The cartridge type rod end canalso accommodate a PTFE liner for self-lubrication. This design is best suitedfor aircraft and military applicationswhere material selection is a primarydesign consideration.
Self-lubricating Rods EndsHeim produces metal-to-metal rod endsand self-lubricating rod ends. All metal-to-metal rod ends, including brass insert fourpiece types, require regular lubrication.This can be accomplished by splash orimmersion oil lubrication, or by greasingthrough optional lubricators (greasefittings). Self-lubricating types are usedwhere relubrication is not practical, or inapplications where relubrication is notdesirable, such as on food processingmachinery or in clean environments. Heimself-lubricating rods ends are available withbonded PTFE fabric liners, or with molded,engineered thermoplastic race inserts.
Rod End GradesHeim rod ends are offered in four grades:precision, commercial, aircraft, andmilitary. Precision rod ends are manufac-tured to tight tolerances for applicationsrequiring improved linkage accuracy andreduced looseness. Commercial rod endsare produced using standard materialsand manufacturing methods, and are aneconomical choice for industrial applica-tions. Aircraft rod ends use premiummaterials, and have magnafluxed rod endbodies. Originally intended for aircraftapplications, aircraft rod ends are used inmany industrial applications where a highdegree of reliability is required. Militaryrod ends are produced in strict accor-dance with all applicable military specifi-cations and are typically used in militaryand commercial aviation applications, orwhen Mil-Spec approval is required.
Precision Rod Ends Grade HM and HF fourpiece precision rod ends use brass race
inserts for lubricity and clearance control.They are produced to tight tolerances forapplications requiring a more precise rodend; for example, a linkage where position-ing accuracy is essential. These rod endbodies and balls are plated for corrosionresistance. Series BHM, HFX G andHMX G four piece precision extra capacityrod ends are the high strength seriesintended for more heavily loaded, static anddynamic industrial applications. These rodends have heat treated bodies for increasedstrength and aluminum bronze race insertsfor high bearing capacity. The rod endbodies are protective coated for corrosionresistance and the balls are chrome platedfor superior wear and corrosion resistance.Series BHM (male) and series HFX G(female) have common thread sizes. SeriesHMX G (male) have oversized shanks foradditional shank strength.

HEIM “D”Self Lubricating Series
For commercial applications where aself-lubricating bearing is eitherdesirable or necessary, Heim devel-oped Heim “D” Series bearings.Heim “D” bearings are designed withan engineered thermoplastic racematerial and offer a lower coefficientof friction than metal-to-metal typesthat use conventional lubricants. It isa resilient material that performs wellunder vibratory and dynamic loadingand withstands dynamic loads up to3500 PSI.
Where to Use HEIM “D”Bearings
Heim “D” bearings should be used inapplications where the bearingcannot be periodically lubricated orwhere it is desirable to eliminate theneed for regular maintenance. Theyare also recommended for applica-tions where there is considerablevibration. The resilience of theengineered thermoplastic race
CFHDCMHD
absorbs vibration without causingfretting or galling of the surface. Thetorque level of the bearing will be lowbecause of the low coefficient offriction of the hardened steel ball onthe engineered thermoplastic race .The coefficient of friction for Heim“D” bearings is approximately 0.1,but will vary somewhat dependingon the loads, speeds, temperatures,and solvents that are present. Thechart on this page shows a typicalbearing wear pattern of Heim “D”bearings and how they vary withnumber of oscillations.
EnvironmentalCharacteristics
Heim “D” bearings have goodenvironmental tolerances. They offeradvantages over bearings that use anylon race because the Heim engi-neered thermoplastic race absorbsvery little moisture. It is generallyresistant to alcohols, aldehydes,esters, ethers, hydrocarbons, weakacids and bases, water and agricul-tural chemicals. Dimensional stabil-ity is quite good when exposed tothese substances, however the Heimengineering department should becontacted for recommendations onspecific performance characteristics.

STATIC RADIAL LOAD
The maximum static radial load permissible for a rod end de-pends on three factors: race material compressive strength; rodend head strength; and shank strength. The maximum staticradial load is determined by taking the lowest of the threefollowing values:
• Race material compressive strengths (R)
R = E x H x X
• Rod end head strength (T)
insert constructionT = [D - (E + .176 H)] x H x X
cartridge type construction
• Shank Strength (S)
male threaded rod endS = [(root diameter of thread2 x .78) - (N2 x .78)] x X
female threaded rod endS1 = [(J2 x .78) - (major diameter of thread2 x .78)] x X
Where:E = Ball DiameterH = Housing WidthX = Allowable Stress (see table)D = Head DiameterN = Diameter of Drilled Hole in Shank of Male Rod EndsJ = Shank Diameter of Female Rod End
STATIC AXIAL LOAD
The maximum available axial load for a rod end is determinedby the following formula. This formula does not take intoconsideration bending of the shank due to a moment of force.Also, this formula does not consider the strength of the stake incartridge type of construction.
• Axial Strength (A)
A = .78 [(E + .176 H)2 – E2] x X
Where:X = Allowable Stress (See Table)E = Ball DiameterH = Housing Width

MISALIGNMENT
The angle of misalignment in a rod end is controlled by the outsidediameter of the head. The maximum degree of misalignment isobtained when the head contacts the side of the fork or clevis inwhich it is mounted.
Maximum misalignment is calculated by the following formula.
• Rod End Angle (α):
ααααα = SIN-1 – SIN-1
Where:D = Head diameter or diameter of outer raceH = Housing widthW= Ball width
T1 = [ ( � D2 - H2 ) + ( x SIN-1 - ) - (O.D. of bearing x H)] x X

Spherical Bearing Technical DataRADIAL LOAD
The maximum static radial load is calculated using the followingformula:
R = E x H x X
STATIC AXIAL LOAD
The maximum static axial load is calculated using the followingformulae:
• Axial Strength (A)
1. For four piece insert construction bearings
A = .78 [(E + .176H)2 – E2] x X
2. For two piece (cartridge type) bearings
A = .65(H2) x X
Where:E = Ball DiameterH = Housing WidthX = Allowable Stress (see table below)

MISALIGNMENT SPECIFICATIONS
The angle of misalignment in a spherical bearing is calculatedsomewhat differently from that of the rod end because thehousing is not spherical. There are three different types ofmountings in which these bearings may be used as shown,and the angle of misalignment is governed by the type ofmounting adopted.
Shown below are the common mountings for sphericalbearings and the corresponding formula for calculating theangle of misalignment.

General InformationSleeve Bearings
Sleeve Bearings
Heim manufactures sleeve bearings ina wide range of materials and sizesfor industrial, agricultural, andaerospace applications. Pages 52 and53 describe two standard series ofself-lubricating bearings that utilizeUNIFLON® Type E liner material.This liner meets the requirements ofSAE-AS81820 (formerly MIL-B-81820).In addition to these standard plainand flanged series, Heim designs andmanufactures “specials” to meetspecific customer requirements.Working either from a drawing,application description or samplepart, Heim also applies UNIFLON®
liners to customer supplied bearings.
Lined Sleeve Bearings(Bushings) - Characteristics
UNIFLON® liners in sleeve bearingseliminate the need for lubricating thebearings during their useful life. TheUNIFLON® liner is a cost effectivesolution to many design problemswhere lubrication is impractical orundesirable. UNIFLON® lined sleevebearings are ideal for applicationswhere periodic shock loads or vibra-tions are encountered. Heim’s newType E liner is recommended forsleeve bearing applications wheretemperatures range from -65�F to350�F. UNIFLON® liners are highlyresistant to most chemical solventsencountered in bearing applications.UNIFLON® lined sleeve bearingshave a lower coefficient of frictionthan metal-to-metal lubricatedbearings. For additional informationon UNIFLON® liner characteristics seepage 54. You are encouraged toconsult Heim’s engineering depart-ment for recommendations on specificapplication problems.
Shaft Data
An important factor influencing thelife of UNIFLON® lined sleeve bear-ings is the condition of the matingshaft. It is recommended that theshaft have a surface finish of 8 RMS orbetter and a minimum surface hard-ness of Rc 40. Commonly preferredshaft materials are hardened corro-sion resistant steels, hard anodizedaluminum and any metal acceptinghard chrome or nickel plate. Themating component should be de-signed such that there are not sharpedges which could damage the linerduring assembly of the sleeve bearing.Cross binding or edge loading on thebearing should be avoided.
Design Inquiry
To request an engineering design on aspecific application, submit either adrawing or sketch or submit thepertinent information. All requestswill receive prompt design engineer-ing attention and follow-up.

Typical Wear Results
Technical DataSelf-Lubricating Bearings
Why UNIFLON® TYPE E?
UNIFLON® Type E liner is recom-mended over other bearing materialsfor the following reasons.
1. High teflon fiber content. Teflonhas the lowest coefficient of frictionof known materials today.
2. The bonding material is apolyallomer consisting of two poly-mers. One polymer provides adhe-sive properties. The second polymerprovides the correct degree ofelasticity.
3. The backing or basic high strength-fabric in Type E has an inherentcoefficient of friction only slightlyhigher than teflon (.019).
Where are UNIFLON® Type EBearings used?
Type E bearings are designed for usein low surface speed high unit loadingwhere metal to metal is limited ornon-desirable. Type E bearings areavailable with ratings in high staticunit loads up to 60,000 psi. Forspecific radial and dynamic loadratings on Type E bearings, consultthe Heim engineering department.UNIFLON® Type E can be used withmany combinations of hardened steel,aluminum, titanium and platedsurfaces, in many environments, andin temperatures -100�F to 350�F.
Type “VV” Liner
For less demanding or higher tem-perature applications, Heim recom-mends its Type “VV” liner. Thehigher temperature Type “VV”carbon filled liner is particularlysuited for high frequency and lowload applications in temperaturesfrom -65�F to 500�F.
The chart above shows the coefficient of friction ofUNIFLON® Type E liner and how this low friction fabricdramatically improves with increasing temperature.
This chart shows a typical wear pattern of UNIFLON® TypeE liner and how it varies with the number of oscillations.
UNIFLON® - Self-LubricatingFabric Liners
To meet the increasing technicaldemands on self-lubricating bearings,Heim has developed UNIFLON® TypeE, a new and improved liner material.Heim’s Type E is qualified to procure-ment specification SAE-AS81820(formerly MIL-B-81820).
UNIFLON® Type E is unique in thefamily of teflon type bearing material.Type E is a low coefficient of frictioncomposite of three materials. Mostcomposite bearing materials consist ofone layer of low coefficient of frictionmaterial usually teflon fiber, layered orinterwoven with either a highlyabrasive fabric such as fiberglass, or alow-load bearing fabric such as dacron,coated with resin. Type E combines alow coefficient of friction, high tensile,high compressive strength fabric withchemically bonded teflon fiber to formthe Type E matrix.

Long Life and High LoadsBurnished races uninterrupted by splits or loading slots,a full complement of large diameter balls, and deepcarburized and hardened raceways give the HeimUNIBAL® ball bearing superior ability to handle highloads and provide longer service life.
Thrust LoadsHeim’s unique design and assembly method providesdeep ball grooves in both races and no loading slots,yielding greater ability to accomodate thrust loads.
Smooth OperationThe burnished races of the Heim ball bearings providefar smoother operation than other unground ball bear-ings. This feature may allow a Heim design to be used inplace of precision ground bearings in many applications.
Easy MountingOptional flanged O.D.s are available to simplifyhousing design and mounting. Heim UNIBAL® ballbearings are also available with extended inner ringsto allow clevis mounting.
