Rod End GradesHeim rod ends are offered in four grades:precision, commercial, aircraft, and military. 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 and HMX 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.

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, and provides 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. The cartridge type rod end consists of a spherical 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 suited for aircraft and military applicationswhere material selection is a primarydesign consideration.

Self-lubricating Rods EndsHeim produces metal-to-metal rod ends and 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 (grease fit-tings). 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.

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 bearing cannot 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 of friction 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 good environmental 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 stabi-lity is quite good when exposed tothese substances, however the Heimengineering department should becontacted for recommendations onspecific performance characteristics.

STUDS

Studs are used in combination with Heim rod ends to simplifymounting. Studs are compatible with the following Heim rod end series:

M CR F CRHM C HF CHM HFCMHD CFHD

The stud is designed to accommodate up to ±25° misalignment in any direction and has a wrench flat to facilitate tightening. Add letter “Y” to suffix to indicate stud. Example: CMHD10Y

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):

α = SIN-1 – SIN-1

Where:D = Head diameter or diameter of outer raceH = Housing widthW= Ball width

• Angles of misalignment for series:

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 static radial load is determined by taking the lowest of the three following 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

angle of expressed in radians

• 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 determined by the following formula. This formula does not take into consideration 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

RADIAL 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 the housing is not spherical. There are three different types of mountings in which these bearings may be used as shown, and the angle of misalignment is governed by the type of mounting adopted.

Shown below are the common mountings for spherical bearings and the corresponding formula for calculating the angle of misalignment.

General InformationSleeve Bearings

Sleeve Bearings

Heim manufactures sleeve bearings ina wide range of materials and sizes for industrial, agricultural, and aerospace applications. Pages 52 and53 describe two standard series of self-lubricating bearings that utilizeUNIFLON® Type E liner material. This liner meets the requirements ofSAE-AS81820 (formerly MIL-B-81820).In addition to these standard plain and flanged series, Heim designs andmanufactures “specials” to meet specific customer requirements.Working either from a drawing, application description or sample part, 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 where temperatures range from -65°F to350°F. UNIFLON® liners are highlyresistant to most chemical solventsencountered in bearing applications.UNIFLON® lined sleeve bearings have a lower coefficient of friction than metal-to-metal lubricated bearings. For additional informationon UNIFLON® liner characteristics seepage 54. You are encouraged to consult 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 the shaft 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. The mating 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 the pertinent information. All requestswill receive prompt design engineer-ing attention and follow-up.

Typical Wear Results

Long Life and High LoadsBurnished races uninterrupted by splits or loading slots,a full complement of large diameter balls, and deep carburized and hardened raceways give the Heim UNIBAL® 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 simplify housing design and mounting. Heim UNIBAL® ballbearings are also available with extended inner rings toallow clevis mounting.

General InformationCommercial Series

Technical DataSelf-Lubricating Bearings

Why UNIFLON®

TYPE E?

UNIFLON® Type E liner is recom-mended over other bearing materialsfor the following reasons.

1. High PTFE fiber content. PTFE has the lowest coefficient of friction of known materials today.

2. The bonding material is a polyallomer consisting of two poly-mers. One polymer provides adhe-sive properties. The second polymerprovides the correct degree of elasticity.

3. The backing or basic high strength-fabric in Type E has an inherent coefficient of friction only slightlyhigher than PTFE (.019).

Where are UNIFLON® Type E Bearings used?

Type E bearings are designed for usein low surface speed high unit loadingwhere metal to metal is limited or non-desirable. Type E bearings areavailable with ratings in high staticunit loads up to 60,000 psi. For specific radial and dynamic load ratings on Type E bearings, consult the Heim engineering department.UNIFLON® Type E can be used withmany combinations of hardened steel,aluminum, titanium and plated surfaces, 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. The higher temperature Type “VV” carbon filled liner is particularly suited for high frequency and lowload applications in temperaturesfrom -65°F to 500°F.

The chart above shows the coefficient of friction of UNIFLON® 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 (for-merly MIL-B-81820).

UNIFLON® Type E is unique in the family of teflon type bearing material.Type E is a low coefficient of frictioncomposite of three materials. Most composite bearing materials consist ofone layer of low coefficient of frictionmaterial usually PTFE fiber, layered orinterwoven with either a highly abrasive 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.
