RBC Thin Section Ball BearingsRBC thin section ball bearings are engineered to solve avariety of design problems that cannot be solved withconventional ball bearings.

A bearing is considered a thin section when the borediameter is greater than four times the radial cross section.Within any thin section ball bearing series, the cross sectionremains constant as the bore diameter changes. Typicallythe cross section is twice the ball diameter, and nominaldimensions are given in inches.

Some advantages of RBC thin section ball bearings are:• Light weight • Multi-load capabilities• High stiffness • Variety of cross sections & sizes• Small cross section • Modified & custom bearings

RBC thin section ball bearings are most often found wherespace limitations, combined loading, and weight restrictionspose unique design requirements.

RBC also designs and manufactures special thin sectionball bearings tailored for specific applications.

Teflon® is a registered trademark of DuPont.Armalon® is a registered trademark of INDACO.

Many molded seals used in bearings are made out ofnitrile (molded rubber per MIL-R-6855). The material hasa relatively high coefficient of friction. In order to meetlow torque bearing requirements, seal fit-up duringinstallation must be adjusted to minimize contactpressure on the sealing surfaces - reducing torque byreducing sealing effectiveness. The inherent variability inthe seal molding process can further aggravate theseissues. Over time, torque fluctuations are nearlyinevitable sInce seals may reset or the amount of lubebetween the seal and the sealing surface may change.Based on these performance characteristics, moldedseals are often marginal end unreliable solutions fortorque sensitive applications.

RBC’s solution is a combination seal-shield design. Theseal is made from either pure PTFE (Teflon®) or glassfiber reinforced PTFE (Armalon®). PTFE is chemicallyinert, has a very low coefficient of friction (inherentlubricity), and provides the widest operating temperaturerange of any sealing material. The seal is held in placeand shielded with a stainless steel (300 series) flat ring.The seal drag torque in this design is minimal,predictable, and consistent over time. RBC invariablyrecommends this design for aIl low torque or torquesensitive applications that require sealing. RBC canreadily retrofit problematic molded seal designs with a PTFE/300SS optImized solution. For versions thatcannot allow a seal, we offer a shield in its place.

ZINC-NICKEL PROTECTIVE PLATING

Zinc Nickel, like cadmium, is a galvanic and a barrierprotective plating technique. Comparatively, the ThinDense Chrome (TDC) used on plain bearings is a barriercoating only.

TDC coating provides barrier protection only, meaninga break in the coating will provide a path for corrosionof the steel underneath. Zinc-Nickel alloy platingprovides galvanic protection similar to cadmium, so that in the event of a break in the plating, the Zinc-Nickel nearby will corrode sacrificially to the exposedsteel, and do so slowly enough to provide service lifeprotection in the proper environment.

THERMAL-COMP™ BEARINGS

Y-PWI

SERIES

THERMAL-COMP™ Bearings are custom designed tocompensate for adverse effects of temperature extremes on bearing performance in airborne applications.

THERMAL-COMP™ Bearings have a double-split ringsdesign and once properly installed in bearing supportstructure at ambient temperature, they will maintain steadyand predictable stiffness and torque characteristicsthroughout a temperature range, regardless of differences in coefficient of thermal expansion (CTE) of the bearing andthe support structure materials.

In most airborne systems, large azimuth bearings areinstalled in support structures (shaft and housing), whichhave to be made from light aluminum alloys in order tocontrol weight. While conventional bearings may beinstalled and fitted for optimum stiffness and rotationaltorque at ambient temperature, significant variations inbearing performance will be experienced at extremes oftemperature in actual application. Such variations arecaused by differences in CTE of bearing materials(hardened steels) and the aluminum alloys used for thesupport structure. At one temperature extreme, the bearingwill be internally over-loaded to a much higher stiffness androlling friction torque; yet at another extreme, the bearinginternal preload may be compromised resulting in loss ofstiffness or excessive deflection. Such undesirablevariations in conventional bearing performance at extremesof temperature will have to be carefully analyzed andconsequences mitigated, often necessitating utilization oflarger drive motors and/or using more expensive supportstructure alloys with CTE properties as close to bearingsteel as possible. With THERMAL-COMP™ Bearingssuch uncertainties in performance are greatly reduced.

The following is a typical illustration of THERMAL-COMP™

Bearings manufactured at RBC-Industrial TectonicsBearings. Note that the free-state gap in ring split isdetermined based on bearing size and applicationtemperatures involved. The gap will be closed to near zerowhen the bearing is operating at the coldest temperature inthe application. The gap will be slightly wider when bearingis operating at higher temperatures. However, bearingperformance will remain consistent.

THIN SECTION BALL BEARING ENGINEERING DATA

ENGINEERINGDATA

The methods, equations, and technical data presentedin this section allow the user to select the correctbearings and estimate their performance for a widerange of applications. For applications with severe orunusual operating conditions, RBC is prepared toprovide an in-depth analysis and recommend the mostsuitable bearing arrangement.

Where standard bearings cannot be used, RBC canmeet the application requirements with a special bearingdesign specifically tailored for optimum performance.Contact your RBC Sales Engineer for special sizes,materials, application requirements, dimensions andtolerances.

Capacity and Fatigue Life of Ball Bearings

The BASIC DYNAMIC RADIAL LOAD RATING, C, or“dynamic capacity”, for a ball bearing is the calculated,constant radial load at which 90% of a group ofapparently identical bearings with stationary outer ringscan statistically endure 106 revolution of the inner ring.ANSI/ABMA Standard 9 with correction factors for racecurvatures was used to calculate the catalog ratings.

The DYNAMIC THRUST and DYNAMIC MOMENT LOADRATINGS are also shown in the product tables. Theratings shown are a guide for the maximum loads underwhich these bearings should be operated with eitherpure thrust or pure moment loading. Thrust ratings are2.5 to 3.0 times the radial ratings depending on thebearing type and cross section. These load ratings arenot additive. For combined radial and thrust loads, anequivalent radial load is to be calculated.

The BASIC STATIC LOAD RATING, Co, or “staticcapacity”, is that uniformly distributed load, whichproduces a maximum theoretical contact stress of609,000 psi. At this contact stress permanentdeformation of ball and raceway occurs. Thisdeformation is approximately .0001% of the balldiameter.

n = number of ballsd = diameter of balls (in.)

The RATING LIFE, L10, is a statistical measure of the lifewhich 90% of a large group of apparently identical ballbearings will achieve or exceed. For a single bearing,L10 also refers to the life associated with 90% reliability.Median Life, L50, is the life which 50% of the group ofball bearings will achieve or exceed. Median life isapproximately five times the rating life. The relationship between rating life, load rating, andload is: L10 = (C/P)3 with L10 = rating life (106 rev)

C = basic dynamic radial load rating (lbf) P = equivalent radial load (lbf)

To obtain the rating life in hours, use: L10 hrs = 16667/N * (C/P)3 with N = speed (rpm)

The Equivalent Radial Load is defined as:P = XFr + YFa with Fr = radial load (lbf)

Fa = axial load (lbf) X - see below Y - see below

Radial Contact Bearing Calculations

For radial contact bearings calculate P with X = 1 and Y = 0. Then recalculate P with X = 0.56 and Y = (see chart below). Use the larger value of P todetermine L10 life.

Page 112: Radial, Angular, and 4-point Contact - RBC Bearings solutions for aerospace, semiconductor, and custom machinery applications. Radial, Angular, and 4-point Contact Thin Section Ball

112

Angular or 4-Point Contact BearingCalculations

For angular contact and 4-point contact bearingscalculate P with X = 1.0 and Y = 0. Then recalculate Pwith X = 0.39 and Y = 0.76. Use the larger value of P todetermine L10 life.

The equations are valid in the range of approximately100 hrs to 100,000 hrs of life. Extreme loads or speedsmay result in a shorter life; while in less demandingapplications, metal fatigue may never affect bearingservice life.

Capacity and fatigue life information is based on ANSI/ABMA Standard 9-1990published by: The American Bearing Manufacturers Association, Inc., 120019th Street, NW, Suite 300, Washington, DC 20036-2401

Adjustment Factors for Rating Life

If a bearing design and operation deviates significantlyfrom normal, it may be necessary to use additionalfactors to estimate the fatigue life Ln.Ln = a1 * a2 * a3 * L10 hrs

with a1 = reliability factor a2 = material & processing factor a3 = application factor

Reliability Factor a1

Reliability is the percentage of a group of apparentlyidentical ball bearings that is expected to attain orexceed a specified life. For an individual bearing it is the probability that the bearing will attain or exceed aspecified life. Typical bearing fatigue life is calculated for90% reliability. The life adjustment factors for otherreliability numbers are shown below.

Reliability % Ln Reliability Factor a190 L10 1.00 95 L5 .62 96 L4 .53 97 L3 .44 98 L2 .33 99 L1 .21

Material Factor a2

For standard bearings the material factor a2 is equal to1.00. Factor a2 is determined by material processing,forming methods, heat treatment, and othermanufacturing methods. Some commonly used materialfactors are listed below:

Application Factor a3

The application factor a3 is equal to 1.0 for mostapplications. Unusual or extreme conditions in certainapplications such as low speed, shock loading,vibration, and extreme temperature may lower theapplication factor to 0.50. Contact your RBC SalesEngineer for help in determining this factor for yourspecial applications.

Load and Speed Limitations

The load ratings shown in the product tables are notadditive. For combined simultaneous loading, anequivalent radial or thrust load must be considered. Ingeneral, C-Type bearings are designed for radial loadingapplications; moderate thrust and/or moment loadingmay be applied in combination with radial loading. Forthrust loading applications use the A-Type bearing; anyradial loading should only be applied in combinationwith thrust loading. X-Type bearings are primarily forreversing thrust and moment loading, pure radial loadingshould not be applied.

The limiting speeds shown in the product tables arebased on standard lubrication. The unsealed bearingspeeds are calculated assuming the bearings arelubricated with MIL-PRF-8085. Limiting speeds forsealed bearings are calculated assuming the bearingsare lubricated with MIL-PRF-23827 grease. If bearingsare lubricated with alternate oils or greases, new limitingspeeds must be calculated, see page 113.

OPERATING CONDITIONS

Lubrication

Lubricants serve a number of very important purposesin ball bearings, including:• protecting bearing surfaces from corrosion• reducing rolling and sliding friction• preventing metal-to-metal contact between balls and

raceway• providing a barrier against external contaminants

(grease)• removing heat (oil)Lack of lubrication or inadequate lubrication is the mostcommon cause of bearing failure. Standard RBC Thin Section Ball Bearings are lubricatedwith either oil or grease. The unsealed bearings, the Kseries, are thoroughly coated in MIL-L-3150 oil anddrained of excess. Sealed bearings are lubricated withMIL-PRF-23827 grease. The external surfaces of sealedbearings are lightly coated with the same grease forcorrosion resistance. Additional lubricants are alsoavailable. Your RBC Sales Engineer can help select theappropriate lubricant for special applications.

Temperature

Standard RBC Thin Section Ball Bearings can operate attemperatures from -65°F to 250°F. Temperatures up to350°F can be reached if the bearings are temperaturestabilized. By the use of special materials RBC canprovide bearings for operation to 900°F. Contact yourRBC Sales Engineer for recommendations on bearingsoperating above 250°F.

Limiting Speed

The limiting speed of a bearing is dependent upon anumber of different factors including bearing size,bearing type, ball separator design, lubrication andloading. The limiting speeds for the bearings shown inthis catalog are determined using the following:

N = with N = Speed (RPM)

E = (Bearing Pitch Diameter)

k = constant, see table below

D+B2

1000 * k E

The k values shown give the maximum speeds at whicha typical thin section ball bearing can operate. It isrecommended that operating speeds of large diameterbearings in a given series be reduced up to 40% of thecalculated rating to avoid high bearing temperatures.Speed ratings can also be impacted by load conditions,lubrication, alignment and ambient temperature. All ofthese factors must be considered when designing thinsection ball bearings into your application.

DUPLEX PAIRS AND AXIAL PRELOADING

Duplex Pairs

Duplex bearings are a pair of angular contact RBC ThinSection Ball Bearings specially ground for use as amatched set. A duplexed pair can be used to provideaccurate shaft location, to increase capacity or toincrease stiffness of the bearing assembly. A duplex pairof RBC Thin Section Ball Bearings is ground so thatwhen mounted using recommended fits, there will be nointernal clearance in the bearings. There are three basicmounting methods to accommodate different loadingrequirements:

• Back-to-Back (DB), B-Type • Face-to-Face (DF), F-Type • Tandem (DT), T-Type

Radial PlayRadial play (diametral clearance) is the distance the innerring can be moved radially from one extreme position to theother. Standard RBC Thin Section Ball Bearings aremanufactured with enough radial play that some clearanceremains after the bearing is properly installed.

When there is negative radial play (diametral preload)there is interference rather than clearance between theballs and the races. As the interference increases, thefriction, stiffness and torque also increase. RBC ThinSection Ball Bearings can be manufactured withcustomer specified diametral preload or clearance.Consult your RBC Sales Engineer for design assistance.

Radial and Axial Runout Radial runout of RBC Thin Section Ball Bearings is ameasurement of the thickness variation of the bearingrings. The outer ring is measured from the ball path to theouter diameter of the ring, the inner ring is measured fromthe ball path to the bore. Radial runout is defined as thewall thickness variation of the rotating ring.

Axial runout is measured from the ball path to the faceof the bearing rings. The variation in thickness measuredis the axial runout.

TOLERANCES

Precision Grades RBC Thin Section Ball Bearings are available in four precision grades. RBC Precision classes 0, 3, 4 and 6 correspond to ABMA ABEC grades 1F, 3F, 5F and 7Frespectively. The tolerances for the bearing bores, outerdiameters, radial runouts, axial runouts and radial plays areshown in the Tolerance Tables on pages 108 through 110.

Shaft and Housing Fits Proper shaft and housing fits are critical to the success-ful operation of a thin section ball bearing. The internalclearance of the bearing will be reduced proportionallyby an interference fit. In addition, the roundness of theshaft and housing will directly affect the roundness ofthe inner and outer ring raceways. For most applicationsthe inner ring is rotating and the load is stationary withrespect to the outer ring. In this circumstance a lightpress fit onto the shaft is recommended. The recom-mended shaft and housing fits are shown in theTolerance Tables on pages 108 through 110.

Axial Preloading

Standard duplex bearings are ground so that there willbe a light axial preload induced on the bearing atnominal conditions. In some applications increasedbearing stiffness may be required. In these cases theduplex grinding can be done such that a heavier axialload is induced in the mounted bearing. This load canbe increased or decreased to meet the requirements ofa particular application. Consult your RBC SalesEngineer for special requirements.

MOUNTING ARRANGEMENTS

When selecting a mounting arrangement for RBC ThinSection Ball Bearings, you must first consider theloading condition. A duplex pair of angular contactbearings may be used for combined loading, momentloading, or heavy thrust loading. Combination A and C-Type, A and X-Type, or C and X-Type bearings arecommon mounting arrangements. Two X-Type bearingsshould never be mounted on the same shaft. There maybe many different bearing arrangements for carrying thesame load, some typical mounting arrangements areshown below.

Reversing Loads

The duplex pair of A-Type bearings offers severalconfigurations. For reversing loads, either Back-to-Back,B-Type, or Face-to-Face, F-Type, should be used. The F-Type mounting method demonstrates reversing thrustload. Combined radial and thrust loads are shown onthe B-Type configuration. Both of these methods can beused for heavy radial loads, combined thrust and radialloads, or moment loads.

Heavy Radial Loads

The C-Type bearing is designed primarily for heavy radi-al loads. Two bearings can be installed on the sameshaft as shown. By axially fixing one bearing and allow-ing the other to float, this configuration allows differen-tial expansion between the housing and shaft, such ascaused by temperature difference, without adding axialstress to the bearings. Although the C-Type bearing isdesigned for radial loads, they can withstand moderatethrust, moment and reversing loads.

Heavy Combined Loading

For heavy combined loading other special mountingarrangements may be employed. As shown in the topdrawing, a duplex pair of A-Type bearings can be usedwith a floating C-Type bearing. In this configuration theA-Type bearings will carry the thrust load and part of theradial load while the C-Type carries only radial load. AnX-Type bearing can replace the duplex pair of A-Typebearings to carry lower thrust loads as shown in thesecond drawing.

RBC manufactures many custom bearings designed tooptimize bearing performance for specific applications.Special features include changes in radial play, lubricants,materials, preloading and design. Contact your RBCSales Engineer for your custom bearing needs.

Challenge us: There are many design options availableto solve difficult application problems.

Materials

The standard bearings shown in the catalog have SAE52100 steel rings and balls. RBC Thin Section BallBearings can be manufactured from other specialtybearing steels to provide corrosion resistance, hightemperature capability, alternative load capacity orchemical compatibility.

Rings. RBC has manufactured thin section ball bearingsfrom SAE 440C stainless steel to provide corrosionresistance. As an alternative to stainless steel rings, theentire surface of the rings can be coated with nodular thindense chrome (TDC). This coating, which meets AMS2438, achieves a molecular bond that will not flake, peelor separate from the base material. The TDC coat has ahardness of HRC 70 - 78 and can withstand temperatureswell beyond the range of the base material.

Special RBC Thin Section Ball Bearings have beenmanufactured from Aluminum, 300 Series StainlessSteel, 17-4 Stainless Steel, and other metals.

Balls. Some special ball materials available include440C Stainless Steel, 300 Series Stainless Steel, SiliconNitride and M-50 Steel.

Lubrication

Many different lubricants are available from RBC forspecial applications. Greases which are designedspecifically for high speed, low torque, water resistance,high temperature, oscillatory motion and food machinerycan be provided. Additional lubricants, such as dry film,are suitable for use in vacuums and space applications.

Sealing

Standard seals for thin section ball bearings are moldedfrom elastomers. Polytetraflouroethylene (PTFE) seals,fiber glass reinforced PTFE seals, stainless steel shieldsand many other options are available for low torque andother special applications.

Radial Play

The radial play (diametral clearance) of a thin section ballbearing will need to be predetermined if mounting fitsother than those recommended are used. Special radialplay may be required for a temperature differential acrossthe bearing, for housing and shaft materials that havedifferent coefficients of thermal expansion, or to changeoperating characteristics of the bearing. Radialpreloaded bearings are measured to meet bore and O.D.tolerances prior to preload.

Preloading of Duplex Bearings

Standard duplex bearings are ground so that there willbe a light axial preload induced on the bearing atnominal conditions. In some applications increasedbearing stiffness may be required. In these cases theduplex grinding can be done such that a heavier axialload is induced in the mounted bearing. This load can beincreased or decreased to meet the requirements of aparticular application. Consult your RBC Sales Engineerfor special requirements.

Mounting Features

Mounting features, such as flanges, anti-rotation tabsand mounting holes can be incorporated on the innerand outer rings. Mating parts, such as gears andhousings, may be integrated into the bearing rings forimproved performance and cost.

Separators

Standard RBC Thin Section Ball Bearings, KA throughKG and JU series, are manufactured with brass or nylonseparators. The KAA series contains nylon separators.The A-Type bearings contain one piece circular pocketseparators, while the C- and X-Types have snap-overseparators. The four basic separator materials are brass,nylon, phenolic and stainless steel.

The graph below schematically illustrates the effects ofcage design and material on bearing performance. Forexample, the one piece circular pocket design may reachroughly two times the speed of the snap-over design.

Likewise, a brass separator design will generate moretorque and withstand higher temperatures than aphenolic separator. Exact speed limits depend onbearing size, bearing type, lubrication and loading.Specific material advantages and limitations areillustrated below. For assistance in selecting theappropriate separator for special applications, contactyour RBC Sales Engineer.

EXTREME ANGULAR ACCURACY BEARINGS

Client Problem

To provide a set of bearings which maintain an extremeprecise angular accuracy of the center line of the shaft tothe housing. The angular accuracy requirement was a non-repeatable error (∆a) of one arc second, and a repeatableerror (a) of three arc seconds.

RBC Recommendation

Bearings should be made to the most precise geometrictolerances possible. The bearings should be preloaded toovercome the minor surface imperfections of the balls andraceways. They should also be part of a cartridgeincorporating the housing and shaft.

RBC Bearing Solution

Bearings were made as part of the cartridge assembly andall angular measurements for accuracy were made relativeto the housing and shaft. Bearings were preloaded andspaced axially to help overcome geometric inaccuracies ofthe bearing. The bearing raceways and balls were madefrom Consumable Electrode Vacuum Melted AISI 440-Cmaterial. As the bearings had to operate in a vacuum, theseparator material necessitated a special open weavephenolic material impregnated with a special silicone oil. To prevent migration of the oil from the cartridge assembly,the labyrinth seal was coated with a barrier film.

Client Problem

Save space and weight in an application involving a powertake-off drive from a high speed gear-box.

RBC Recommendation

Make the races of the bearing integral with the housingand possibly with the gear shaft.

RBC Bearing Solution

The bearing housing was designed to incorporate the outerraceway of the roller bearing and the outer raceway of thesplit inner race ball bearing. In order to increase the relia-bility of the rolling contact surfaces in the housing, thehousing was manufactured from AISI M-50 materialConsumable Electrode Vacuum Melted. The gear wasmade integral with the shaft which also contained the innerraceway of the roller bearing. The gear shaft was manufac-tured from Consumable Electrode Vacuum Melted AISI-9310 material; case hardened to Rc 61-64 on the geartooth surface and in the roller bearing raceway. In order tofacilitate lubrication of the bearings in the restricted area,lubrication holes were drilled through the housing into thespace between the two bearings. The lubrication was fedthrough these holes from an annular groove in the housing.The two halves of the split inner race were retained to thegear shaft by the use of a lock nut, clamping the races axi-ally. The combined integral assembly of bearings, gearshaft and housing provided the desired space and weightreduction and gained improved operational accuracy. Inaddition, it afforded easier installation into the gear-box.

THIN SECTION GEARED BEARING

ROLLER, THRUST AND ANGULARCONTACT BALL BEARING

TYPICALAPPLICATIONS

Client Problem

A radar antenna drive had only limited space available forits support bearings.

RBC Recommendation

Use a thin section rather than a standard section radial ballbearing, thus achieving a significant weight reduction.Incorporate a gear as part of the inner ring to obtainimproved accuracy and simplify the assembly.

RBC Bearing Solution

The thin section bearing utilizes coil springs as spacersbetween the balls instead of a conventional separator tofurther reduce weight and lower bearing torque. The innerrace of the bearing was extended and the gear was cut onthis extended portion of the inner race. The incorporationof the gear into the inner race eliminated the necessity of ashaft clamping mechanism, etc., which would be requiredif the gear were separate from the bearing. Integrating thegear profile into the inner race increased the accuracy ofthe gear to bearing concentricity. The bearing wasmanufactured of the following materials: the balls andouter race are from AISI-440-material; the inner racemanufactured from AIS1-8620 material, carburized andhardened in the raceway area to Rc 58-60.

Client Problem

Cost reduction of an existing hydraulic pump swash plateassembly.

RBC Recommendation

Utilize an integral bearing assembly which combines aroller thrust bearing and an angular contact ball bearing.

RBC Bearing Solution

The original swash plate design in the hydraulic pumputilized a roller thrust bearing to handle the thrust load anda separate angular contact radial ball bearing to handleradial loads; and radially locate the swash plate assembly.The usage of two separate bearings required complexmachining of the housing and swash plate with closecontrol of tolerances, to eliminate excessive radialeccentricity of the swash plate assembly. In the originaldesign, which utilized two separate bearings, it wasnecessary to mount the bearings axially adjacent to eachother. The recommended bearing design decreased theaxial space required for bearings, resulting in a size andweight savings. A combined bearing assembly is usuallylower in cost than two separate bearings. The technique ofintegrating two bearings usually simplifies an assemblywhere two bearings had been utilized, or where problemshave arisen relative to running accuracy, overall size orweight.

SELF ALIGNING BEARINGOPERATING IN LIQUID

POLYETHYLENE

SENBAL BEARING

Client Problem

A rolling contact bearing was required on a vertical shaftwhich rotated in a catalytic-polyethylene autoclave. Blindassembly of the bearing and shaft which weighedapproximately 10,000 pounds was necessary, due to theautoclave design.

RBC Recommendation

Use radial ball bearing incorporating a self-aligningraceway made from corrosion resistant materials. Thebearings should be capable of withstanding operatingtemperatures as high as 650°F, and capable of operatingwith liquid polyethylene as the lubricant.

RBC Bearing SolutionThe bearing was manufactured from AISI-440-C material,specially heat treated to resist softening at the highoperating temperatures. The separator material was L-605cobalt alloy which offered the necessary wear resistance.

To solve the client’s problem of inserting the eighteen footlong assembly into a blind housing, a large lead-in chamferwas formed on the outside of the bearing. This lead-inchamfer provided for easy insertion of the bearing into thehousing.

The previous bearing installation did not allow any shaftmisalignment, resulting in bent shafts which were thenunacceptable for further use. The self-aligning feature ofthe outer raceway permitted the bearing to misalign whilerotating, allowing for shaft distortion as the shaft wentthrough critical speeds.

Client Problem

A fluidic gyroscope required a gimballing, self-aligningbearing which would rotate at high speed. The bore of thebearing was to form part of the fluidic metering andsensing system.

RBC Recommendation

Use a double row, self-aligning spherical ball bearing withspherical outer and inner raceways. The two rows of ballsshould be preloaded to obtain the running accuracyneeded for the fluidic metering system in the bore of thebearing.

RBC Bearing SolutionThe double row spherical self-aligning ball bearing wasdesigned with a removable portion of the spherical outerraceway to allow for preloading of the two rows of balls.

With the possibility of different rotational speeds of the tworows of balls, each row of balls had its own separator. Toguide the separators, a special configuration wasmachined on the outside of the separator to allow for eachseparator to be guided at two points of contact with thespherical outer raceway.

The fluidic metering portion was made as a separate unit,press fitted into the bore of the bearing.

GEARBOX BEARINGS WITH SELFLUBRICATING SEPARATORS

TYPICALAPPLICATIONS

Client Problem

A high temperature rolling contact, oscillating bearing foroperation at 1200°F, subjected to high vibration loads.

RBC Recommendation

Design a rolling contact bearing with radial preload toovercome false brinelling which may occur in the highvibration environment. Bearings should be made from acorrosion resistant, high-temperature alloy.

RBC Bearing Solution

The bearing was manufactured of Stellite® 6B materialwhich was cold worked by an RBC proprietary process toobtain a hardness of Rockwell C-53 minimum in theraceway areas. The balls of this bearing were made fromL-605 cobalt alloy. The bearing was of full complementdesign with a filling slot for insertion of the balls, andnegative radial clearance of line to line to .0003" tight.

The lubricating film which is generated by the cobalt alloyraces and balls permitted this bearing to operate withoutany additional lubricant. The increased hardness of theraceways to Rockwell C-53 minimum produced a bearingwhich was capable of operating up to 1200°F with extremewear resistance.

Client Problem

Bearings were needed for operation in high-temperaturegear-boxes at 600°F to 650°F. Conventional lubricationsuch as oil was not available, therefore the bearings wouldhave to be self-lubricating.

RBC Recommendation

Use bearings of high-temperature, heat treated AISI-440-Cmaterial. Incorporate in these bearings RBC developedproprietary graphitic carbon separators, to act as thebearing lubricant.

RBC Bearing Solution

Angular contact ball bearings were designed, utilizing aninner land guided separator of graphitic carbon material.The separator was reinforced on its outside diameter witha metallic shroud to withstand the centrifugal forces fromhigh operating speeds and resist fracturing, which couldresult from the tremendous acceleration rate of the bearingrotation.

To facilitate a break-in period required for transfer of theself-lubricating material from the graphitic carbonseparator to the rolling contact surfaces, the balls andraceways were coated with an impinged, tungsten-disulfide dry-film lubricant of approximately .000020" inthickness. With the dry film lubricant on the raceways andballs, the bearings were capable of operating at therequired speed without any break-in period normallyrequired for bearings incorporating dry, self-lubricatingseparators.

HIGH TEMPERATURE, ACTUATORTHRUST BEARINGS

Client Problem

A high temperature thrust bearing was needed to supportthe reactive thrust of a ball screw actuator. Bearings had tobe capable of operating at approximately 850°F.

RBC Recommendation

Use bearings of high temperature tool steel to withstandthe applied loads at the high operating temperature.

RBC Bearing Solution

Bearings were manufactured from CEVM M-2 tool steelwith a full complement of sixteen .187 diameter tungstencarbide balls. The bearing was designed having a contactangle of 60° to handle the high thrust load and some radialloading.

The races were coated with a proprietary dry-film lubricantapplied to the raceways of the bearings prior to installationof the bearing in the application.

The significant design feature which allows the bearings tooperate at 850°F and at speeds up to 750 RPM withoutexcessive wear is the combination of the tungsten carbideballs running against the M-2 tool steel raceways. Similardesigns using M-2 tool steel balls had worn very rapidly atrelatively short periods of application at the operatingtemperatures.

Client Problem

A newly designed rotating magnetometer for ore analysisrequired a non-magnetic bearing.

RBC Recommendation

Use a bearing with the raceways and balls made of amaterial which would be capable of operating under theloads and possess the lowest magnetic permeability. Theloading combined thrust, radial and moment loads whichrequired a duplex pair of bearings.

RBC Bearing Solution

Manufactured the bearing from Berylco 25 material. Thismaterial was used for the inner and outer races, balls andshields. The separator was manufactured of a phenolicmaterial.

The bearing was designed as a common outer duplex DBpair, lightly preloaded. To reduce contamination possibility,shields were incorporated. The bearing was lubricated bygrease plating the raceways with MIL-PRF-23827 lubricant.

Client Problem

A hinge bearing on the exhaust ducts of a jet engine usedto propel and lift a ground effect vehicle machine.

RBC Recommendation

Use a double row angular contact ball bearing in a self-aligning housing. Bearing materials to be made of corrosion and heat resistant material.

RBC Bearing Solution

The double row ball bearing cartridge unit utilizes L-605 material for the raceway and balls. The bearing was mounted in a self-contained spherical housing tocompensate for misalignment of the shaft during operation,which occurs due to temperature differentials between theframe and the exhaust nozzles.

The races were made by a special RBC developedproprietary race hardening technique.

With this technique the L-605 cobalt alloy material is workhardened and then heat treated to a Rockwell C-53minimum.

The bearing operated for 50 hours with 1400°F exhaustgas passing through the bearing without any significantwear.

Client Problem

A manufacturer of commercial aircraft required a landinggear support trunion bearing.

Bearing must have low radial and axial clearances.

RBC Recommendation

Use a metal-to-metal spherical plain bearing. It shouldhave a dry film lubricant on its spherical bearing surfaces.The bearing should be fabricated from corrosion resistantmaterial.

RBC Bearing Solution

With the clearances required, .0010/.0030 radial and .009max. axial, assembly of match ground components wasnecessary. Swaging a bearing of this size would not resultin reliable clearance control. The outer race wasassembled to the ball by deforming it under radial pressureto an elliptical shape to allow the insertion of the ball. Oncethe ball is inserted, the pressure is removed from the outerrace, allowing it to return to its original shape.

FOOD PROCESSING EQUIPMENTBEARINGS

Client Problem

Relatively short life was obtained on bearings made of 316 stainless steel in food processing equipment. 316 stainless steel was required to prevent contaminationof the food products.

RBC Recommendation

Use a harder, more wear resistant material which wouldstill be resistant to the corrosive fluids of the processedfood and prevent contamination.

RBC Bearing Solution

A search of various materials which were resistant to the food products handled by this particular piece ofequipment brought to light that certain cobalt alloys couldbe used without any fear of contamination or corrosion.

In order to increase the wear resistance of the cobaltalloys, they were cold worked in the raceways to increasethe hardness and thereby increase the wear resistance.

The alloy used for the raceways and the balls was L-605. Separator material was 17-4 PH.

Client Problem

Bearings exposed to photographic-processing chemicalsolutions were failing. Bearings being used were made ofAISI-440-C material, sealed, and grease lubricated.

RBC Recommendation

Use a bearing of a different alloy; make the separator self-lubricating and run the bearing in the chemical solutions.

RBC Bearing Solution

The bearing used cobalt alloy balls and races and a self-lubricating separator of Fiberglass reinforced TFE. To giveadditional strength to the riveted separator in this bearing,side plates of 300 series stainless steel were added to theseparator.

High speed ball and roller bearings for use in cryogenicequipment. Bearings should also operate in cryogenicliquid or gaseous environment.

RBC Recommendation

Use bearings of a corrosion resistant material such asAISI-440-C and incorporate a self-lubricating material forthe separators.

RBC Bearing Solution

Ball and roller bearings of ABEC-5 tolerance grade weremade of AISI-440-C material, with special sub-zerotreatment in liquid nitrogen. This sub-zero treatment gavethe bearings the dimensional stability necessary foroperating in cryogenic equipment.

The bearing separators were made of Teflon reinforcedFiberglass.

This basic bearing design criterion has been used inalmost all liquid hydrogen and oxygen turbo pumps usedin present day rocket engines.

Client Problem

Mainshaft bearing for a vertical lift engine. For weightreduction, the bearing should be self-lubricating toeliminate a portion of the engine lubricating system.

Speed of the 85mm bore bearing was 16,000 RPM. Thebearing, located in turbine end of the jet engine,accommodates axial shaft expansion.

RBC Recommendation

Use a ball bearing with races and balls made from wear-resistant materials. Lubricate the bearing with a shroudedself-lubricating graphite separator. Make the inner racecylindrical to accommodate the axial shaft expansion.

RBC Bearing Solution

Bearing was manufactured from CEVM AISI-M50 materialfor the races and balls.

The separator of shrouded graphite was outer land guidedon two graphite rings, pressed into the outer race ring.

To prevent damage to the graphite while inserting the shaftinto the bearing, a side plate was added which preventedany accidental contact of the shaft with the graphiteseparator. To allow for the excess graphite to purge fromthe bearing, holes were put in the protective side plate.

NUCLEAR REACTOR BEARING

Client Problem

Bearing to accommodate the thrust load in a control roddrive mechanism. Bearing is lubricated with chemicallypure water, de-ionized and de-oxygenated.

RBC Recommendation

Use a double row ball bearing, tandem ground for thrustsharing to obtain the life required. Because radial supportof the inner race is marginal, the inner race for both rowsshould be ground on the same ring.

RBC Bearing Solution

The double row ball bearing was made of cobalt alloymaterials, the separator of 17-4 PH.

To obtain the maximum capacity in this double gothic archthrust bearing, the outer races are split, permitting themaximum quantity of balls in each row. Thrust sharing oftwo rows is accomplished by accurate match grinding ofthe spacer ring to fit the gap between the outer races, andby matching the contact angle in both rows equal withintwo degrees.

CAMERA MOUNT BEARING

Client Problem

A lightweight, low torque bearing for use in an aerialcamera assembly.

RBC Recommendation

Use a bearing with rings made of aluminum, and hardanodize the raceway areas.

RBC Bearing Solution

The original steel bearing design which was a double rowangular contact ball bearing in an aluminum housing wasreplaced with a single row, 4 point contact bearing, withthe rings manufactured of 7075-T-651 aluminum. Theraceways of both rings were hard anodized and groundafter hard anodizing. Balls were of passivated AISI-440-C.

This construction utilizing the aluminum material, reducedthe overall weight of the bearing assembly from over 7 lbs. in the original design to 3.8 lbs. in thefinished unit.

In order to obtain a low running and starting torque,alternate balls in the raceway were surrounded with TFEseparator and the raceways were grease-plated. Thebearing running torque was below 1 inch lbs. with thestarting torque being below 2 inch lbs.

Client Problem

A ball bearing running at 2.2 miIlion DN*, with no load, wasfailing due to the fatigue of the outer race, and ballskidding. Fatigue failures had been occurring due to thelarge number of stress cycles, caused solely by thecentrifugal force of the balls.

RBC Recommendation

Reduce the number of balls in the bearing, therebyreducing the number of stress cycles on the outer race.

Make the separator a lightweight steel design. Reductionof the separator and ball mass would reduce the inertialresistance, thereby reducing skidding. Change materialfrom AIS1-52100 to a tool steel to increase resistance toskid damage.

RBC Bearing Solution

Bearing races and balls were made from CEVM AISI-M50 tool steel. The separator was manufactured from AIS1-4340 material, hardened to Rc 26-32 and silver plated.

The number of balls was reduced from twenty to eightballs, reducing the number of stress cycles by sixtypercent.

The separator configuration permitted an increase of lubricant flow through the bearing for cooling andlubrication.

*DN = D, bearing bore in (mm) - N, shaft speed in (RPM).
