Ball Bearing Size Selection

A bearing should be selected with a load rating the same asor greater than the actual load. Where overloads, shock,vibration or thrust loads are encountered, use the largestequivalent load to select the bearing, as shown in thefollowing three paragraphs.

1. For applications involving frequent overloads, theoverload value should be used as the equivalent load.

2. For applications involving shock loads or vibration, add upto 50% of the actual load to find the equivalent load.

3. If thrust loads exceed 50% of the radial load, add thethrust load to 50% of the radial load to determine theequivalent load.

When an L10 life of over 30,000 hours is required, multiply theactual or equivalent load by the following factors:

1.10 for 40,000 hours L10 life1.26 for 60,000 hours L10 life1.39 for 80,000 hours L10 life1.50 for 100,000 hours L10 life

Find this new value in the table opposite 30,000 hours L10 lifein order to select a bearing.

The L10 life as given in the table is defined as the number ofhours that 90% of a group of bearings will operate before thefirst evidence of fatigue develops. Average life isapproximately five times L10 life.

Because of the high load permitted at low speeds, shaftstrength and housing clamping bolt strength should bechecked for low speed operation. Heavy thrust applicationsrequire a shouldered shaft back-up against the face of theinner ring or an added thrust collar.

Mounted bearing units have the advantage of providingproper load support and reducing design and assembly time.Pre-mounted bearing units offer convenience as well aseconomy and it is not necessary to spend valuable timeselecting bearing housings, seals and different methods ofsecuring the bearings to the shafts. Selection informationusually necessary is shaft size, radial and thrust loads, speedand physical mounting limitations and operating environment.

The simplest, most economical mounting is set-screw lockingthrough the inner race…which securely locates the twomembers. The extended inner race provides maximum shaftcontact along with good bearing stability. For someinstallations, standard commercial shafts are successful witha slip fit in the inner race bore, although some instances,press fitting of the shaft to the inner race is required.

The amount of inner race bore to shaft O.D. clearance thatcan be tolerated depends upon application and operatingconditions. For instance, if dynamic balance is important, aclose fitting shaft to inner race bore is very desirable. Severevibration could be experienced when using undersize shaftsof varying degrees resulting in the undersize shaft becomingeccentric in the bore of the inner race, regardless of the typeof locking method.

Three types of shafting are normally used in ball bearingpillow block applications. For example, it is very common toutilize commercial grade mild steel shafting. If closertolerance shafting is required, then either turned, ground andpolished or cold drawn, ground and polished shafting is used.

If more precise shafting is required, it can be selected to, orpurchased, with a +.0000 –.0005 diameter tolerance and it isusually to the nominal diameter with a negative tolerance.

If the dynamic balance is important, slightly oversize shaftingshould be used to provide a snug fit with the bore of theinner race. In other words, it should be a line to line fit to aninterference fit rather than a line to line to a non-interference fit.

Special mounted bearings

In addition to standard bearings cataloged, bearings areavailable with special surface finishes, special sealingarrangements and specialized housing or bearing insertconfigurations.

Special surface finishes

A black oxide surface finish treatment can be applied to ballbearing inserts to meet special application requirements. Theblack oxide finish is applied for corrosion resistance, andprovides excellent protection for the majority of applicationconditions. Also, it is far less costly than a plated bearing or abearing made entirely of stainless steel.

Nickel plated pillow blocks

A variety of standard mounted units have been supplied withnickel-plated castings for food processing or food packagingapplications. Bearing inserts with black oxide finishes arenormally supplied with nickel-plated casting unless otherwisespecified. Stainless steel set screws are considered optionaland would not be included unless specified. Applicationswhere nickel-plated mountings are being used include:vegetable peeling, fruit and vegetable forming and stackingequipment, shrimp peelers and many conveyor applicationswhere the bearings are exposed to food acids, as well asdaily detergent and steam washdowns. Nickel plated housinghave excellent corrosion resistance (approaching that ofcadmium plating) and wearability similar to chrome plating.These bearings are prelubricated with an odorless, tastelessgrease that meets Section 121.2553 subpart F “Lubricantswith Incidental Food Contact” of the food additive regulationof the Good and Drug Administration. The lubricant hascapabilities to adequately lubricate antifriction bearings underwet or dry conditions and in normal ambient temperatures toan operating temperature of +225°F.

Nickel plated units are available in C25, FC225, FC425,TC25 configurations in 1/2" to 115/16" bore sizes. Catalognumbers of nickel plated units are formed by adding theprefix letter N ahead of the standard bearing number.Example – C25-12 standard pillow block becomes NC25-12with nickel plating and corrosion resistant bearing insert.

Specialized housings or bearing inserts

Specialized housing or bearing insert configurations arefrequently supplied to suit application needs. A fewexamples are:

Non-standard based to shaft centerline height,

Relocation of lube fitting,

Non-standard mounting bolt hole location or shape,

Triangular flange castings,

Dust closures, one side of housing,

Double extended inner ring bearing inserts with set screwson each side,

Square and hex bore bearing inserts, and

Triple contact lip sealing, commonly called for in farmequipment applications.

Special housing designs may be proprietary and notavailable to others. However, in some cases tooling isstandard and existing special designs can be made available.Special paint colors or types are also available, and…

Some customers have made use of a special marking optionavailable with MB bearings. The units can be marked withcustomer identification (name) and/or number. This“personalizes” the unit and the equipment in which it is used.

Instructions for installation and lubrication ofmounted ball bearing units

CAUTION

Failure to comply with proper installation, lubrication andmaintenance procedures could result in catastrophic bearingfailure. If operating in an explosive environment or in oraround combustible materials, such catastrophic failure couldlead to property damage and personal injury.

Important Notice The performance of any mounted unit isdependent upon proper installation, lubrication andmaintenance. Premature failure may result if recommendedinstructions are not followed.

Installation

1 The shaft must be clean and free of nicks and burrs. Ifmounted on used shafting, the bearing must be locatedon a smooth, unworn section.

a. A ground shaft must be used to obtain a snug fit,except where the unit is used for heavy loads, highspeeds or where dynamic balance is critical, in whichcase a light press fit is required. The following shaftdiameters and tolerance must be used to obtain asnug fit:

Heavy loads are greater than 15% of the BasicDynamic Rating (BDR) of the bearing used in themounted unit. The Basic Load Ratings are shown onpage 10 or page 40. High speeds are those definedas being in excess of 1,500 feet per minute.

b. To obtain a light press fit, a line-to-line fit between thebearing bore and the shaft diameter must be maintained.Any fit tighter than line-to-line can cause prematurebearing failure. Thus, selective fitting of bearing bores andshaft diameters is required to maintain proper light press

fit for heavy loads, high speeds or when dynamic balanceis critical.

c. For moderate thrust loads, shock loads, vibrationconditions or higher speeds, the shaft should be spotdrilled to provide additional holding. Heavy thrust loadapplications require a shouldered shaft back-upagainst the inner ring face, or an added thrust collar.

2. Even very small raised edges and burrs on the mountingsurfaces can lead to overstressing and fracture of thehousing. Therefore, the support member surface to whichthe housing will be mounted, and the housing mountingsurface, must be clean and free of burrs and nicks thathave raised edges, so that a smooth, flat mountingsurface is present. Careful handling of mounted units isrequired to avoid damage to the mounting surface.

3. Slide the unit on the shaft by applying light pressureagainst the face of the inner ring. DO NOT HAMMERTHE ENDS OF THE INNER RING OR ANY PART OFTHE HOUSING.

4. Bolt the housed units securely to the support members.

5. Tighten the set screws of one bearing locking device tothe recommended torque values given in Chart 1, below.

a. Bearings with the concentric setscrew locking devicehave no collar-the set screws in the inner raceextension tighten against the shaft.

b. Bearings with the CENTRIK-LOK locking device havea collar. The set screws in the collar are started intocountersunk holes in the inner race extension. Theseset screws must be tightened to the Chart 1recommended torque values into these countersunkholes to obtain satisfactory and efficient locking tothe shaft.

6. Check the shaft for freedom of rotation. If possible, runthe bearings a short time under the load.

7. Tighten all bearing set screws to the Chart 1recommended torque values.

Lubrication

All standard MB ball bearing mounted units are prelubricatedwith grease and must be periodically relubricated to obtainfull bearing fatigue life. This is even more important whenthese units are used in a dusty or moist environment. Therequired lubrication cycle will be dependent upon theoperating conditions, speed, temperature, dust, moisture andother environmental conditions. The following lubricationguide must be followed to prevent catastrophic bearingfailures:

1. Grease should be added slowly while the shaft is rotating,until a slight bead of grease forms at the seals. Thisindicates the correct amount of grease has been added.A slight grease leakage at the seals is beneficial as itassures lubrication of the seal contacts, purging of oldgrease from the bearing and provides protection in theform of a grease dam against contamination.

CAUTION: Proper care must be exercised duringrelubrication to avoid any rotating parts that would causepersonal injury.

2. MB mounted ball bearing units are prelubricated withlithium base grease for normal operating conditions and atemperature range of –20°F to +275°F. These units mustbe relubricated with a lithium base grease, or a greaserecommended by a reputable grease manufacturer asbeing suitable for ball bearings and compatible withlithium base greases.

a. Relubrication will generally cause a slight rise inbearing operating temperature until the bearing hasstabilized with the proper amount of lubricant. Undernormal conditions, this slight rise in operatingtemperature should not exceed 30°F. This will usuallytake place within a period of 10 to 30 minutesfollowing the relubrication.

b. Some environmental operating conditions, such as anunusual amount of dust, operation in dirt or in moistenvironments, will require more frequent relubricationwith as much grease as possible while maintaining anormal bearing operating temperature range ofambient to approximately 210°F. Relubrication shouldbe as often as necessary to maintain a slight greasepurge at the seals.

c. In the event bearings are to be stored in a wet, dustyor corrosive environment, extra protection must beprovided by first adding grease and rotating thebearing until the grease is seen at the seals. Inaddition, fresh grease must be added beforeoperation, when stored under such adverseconditions.

3. Special optional sealing arrangements are available forunusual adverse operating conditions. Normally, a specialgrease prepack is required in conjunction with specialsealing arrangements. The Rexnord Bearing ProductsEngineering Department should be consulted for specialapplication conditions and/or abnormal or severeenvironmental conditions.

IMPORTANT NOTICE

Periodic relubrication, at a frequency that will be determinedby application conditions, is absolutely necessary to avoidcatastrophic bearing failure.

In addition, periodic inspection must be made to assurecontinued satisfactory bearing operation. During suchperiodic inspection, bearing operating temperatures shouldbe checked. If operating temperatures are found to be rising,the reason for this should be determined. It may be thatreplacement of the mounted bearing is required.

Temperature sensitive crayons and temperature sensitivelabels can be used for determining bearing temperature.Marking the housing with temperature sensitive crayon orapplying a temperature sensitive label to the housing willindicate if the bearing operating temperature has exceeded aprescribed level. At any time the bearing operatingtemperature has exceeded a prescribed level, or any time thebearing operating temperature exceeds 210°F, the reasonshould be be determined. Replacement of the mounted unitmay be necessary.

Special procedures and safety codes must be followed. Thismay require the use of protective guards or other devices.Temperature sensitive crayons or labels, protective guardsand other safety devices are not provided by MB nor is theiruse or lack of use the responsibility of Rexnord BearingProducts.

Bearing Insert Replacement

1. The MB bearing insert has mounted in its sphericaloutside surface and anti-rotation pin, unless the bearingpackage is marked “–W/OP.” To be effective, this anti-rotation pin must engage one of the loading slots in thecast housing.

2. In addition to the anti-rotation pin, MB housings andbearing inserts are fitted together to provide controlledlimits on torque required to align the insert in thespherical seat of the housing. Failure to observe theprescribed alignment torque values can lead to prematurebearing failure. Those alignment torque values can beobtained from the Rexnord Bearing Products EngineeringDepartment.

CAUTION:

The replacement of MB inserts into housing of othermanufacturers can lead to premature bearing failure. Thelubrication fittings in other housing designs may not line upwith the lubrication groove and hole in the outer ring of theMB bearing insert. If that occurs, the bearing will not receivelubricant at relubrication and early, and possible catastrophic,failure can occur:

3. Installation of an MB bearing insert into an MB casthousing is initiated by installing the bearing into thehousing insertion slots with the bearing turned 90 from itsnormal position, and with the anti-rotation pin located inone of the insertion slots. Care must be exercised toavoid shearing the rotation pin when the bearing is gim-baled to its final position, and the bearing must be gim-baled so that the anti-rotation pin (located closer to oneface of the bearing out race) is in position toward theinsertion slot face of the casting. Further, the bearinginsert should be installed so that the lubrication hole inthe outer ring outside surface is approximately in line withthe lubrication fitting in he housing. The lubrication groovein the outer ring outside source must be under thehousing lubrication fitting.

4. After bearing insert assembly in housing, the aligningtorque must be checked with a torque wrench to verifysatisfactory aligning torque. Failure to do so and/orshearing the anti-rotation pin can lead to spinning of thebearing outer race in the housing with resultant housingwear and premature unit failure.

KROWN REGAL CENTRIK-LOK MOUNTED Ball Bearings (cont.)

The KROWN REGAL bearing design reduces the three mostcommon causes of bearing failure – seal failure that permitsentrance of contaminants or loss of lubricant; insufficienthousing strength; and loosening of bearings on rotatingshafts. Other features include large diameter balls for highload capacities, nylon retainers for quiet operations,conveniently located lube fittings and superior anti-rotationpin arrangement.

Molded Lip Seal-Flinger System

The sealing system provides four-way sealing action toeffectively keep dirt out and lubricant in. It is combined inKROWN REGAL bearings with steel flingers that throwexcessive contaminants away from the bearings and protectthe seals from damage by abrasives and impact. Together,the superior seals and added flingers add significantly tobearing life.

Rugged one-piece cast iron housings

These bearings have heavier cast iron housing than previousdesigns. The KROWN REGAL foot-mounted pillow blocks andflange mounts are built to withstand heavy loading, shockand external vibration. Finishes are highly resistant tocorrosion and abrasion.

CENTRIK-LOK shaft locking device

Bearing-to-shaft locking is accomplished with the patentedCENTRIK-LOK shaft locking device. This method of lockingprovides excellent holding power versus competitive shaftlocking devices. Its clamping action also centers the shaft inthe bearing to avoid vibration and noise. It also eliminatesshaft damage because set screws do not contact the shaftmaking bearing removal easier.

Spherically-seated bearing insert with anti-rotation pin

The spherical fit between the outer race O.D. and I.D. of theblock is precisely controlled for easy shaft alignment. An anti-rotation pin is permanently installed in the bearing insert O.D.It engages one of the housing insertion slots, preventingouter race creep and war of housing. There is no danger oflosing a separable pin during field replacement of bearingsand no danger of preloading the bearing as is possible inother designs where a lube fitting is tightened against alocking pin.

The CENTRIK-LOK shaft locking device (Pat. No. 4,403,814)assures precise centering of MB KROWN REGAL ballbearing pillow blocks and flange-mounted units on rotatingshafts to avoid vibration and noise. What’s more, the inherentholding power of this unique design can be far superior toother equivalent competitive bearings. An important feature ofthe CENTRIK-LOK shaft locking device is that the lockingcollar is pre-assembled onto the bearing inner race, avoidingthe problem of loose, lost or misplaced locking collars.Another feature is that the set screws do not come in contactwith the shaft and therefore, do not mark the shaft or leaveheavy burrs that make bearing removal difficult.

Most mounted bearing locking devices move the inner raceeccentrically on the shaft during locking. This eccentricpositioning of the inner race can cause vibration, loosening oflocking devices and loss of bearing performance.

One of the drawback of current locking devices that domaintain concentricity has been their lack of shaft-holdingpower. The CENTRIK-LOK shaft locking device overcomesthese shaft-holding limitations and still provides theadvantages of true concentricity. The inner race is slotted infour places and a continuous cylindrical locking collar isapplied over the inner race slots. Two set screws, located 45apart, contact the inner race on each side of one of the slots.The two set screws exert force on two of the four inner racesegments and the resulting reaction through the collar pullsthe remaining two segments against the shaft concentrically.

Standard Krown Regal optional sealing arrangements

Standard steel clad type N single lip seals have a usefultemperature range of –40°F to +225°F and can withstandtemperatures up to 250°F for intermitent service. The flingeradds protection against contamination, and can shieldagainst radiant heat. Special sealing arrangements areavailable for higher temperatures and “free-running” orspecial contamination resistance.

Special optional sealing arrangements

Suffix-MHFF indicates type H seals and flingers both sides.This provides a sealed, “free-running” bearing with heatshield protection. It is satisfactory for temperatures from–40°F to +275°F.

Rexnord Bearing Products must be consulted regardingavailability of any of these optional sealing configurations.

Examples for ordering:1. Bearing Insert KMB451–716–MHFFPA2. Mounted Unit KC451–716–MHFF

High temperature ball bearing inserts and housed units

Krown Regal mounted ball bearings and KMB45, KMB55 andER series inserts are available for high temperatureapplications up to 400°F. The “E1” package provides thefollowing features:

1. Extra Internal Diametral Clearance (DC) based on a200°F temperature differential between inner and outerraces, compensates for the inner race expanding at afaster rate than the outer race and will avoid preloading ofthe bearings.

2. Steel Retainer (Cage) – 2 piece riveted construction.

3. High Temperature Lubrication – prelubricated with a No. 2consistency bentone-base grease with petroleum oil.When operated near upper limit, (400°F to 450°F) dailyrelubrication is required.

4. Viton Seals withstand temperatures to 400°F.

5. Steel Flingers are mounted outboard of the Viton sealswith an interface fit with the O.D. of the inner ring.

Examples for ordering:1. Bearing Insert KMB451–716–E1PA2. Mounted Unit KC451–716–E1

Free running applications and applications above 400°F

Sealing options such as –FF (flingers only) for “free running”applications and/or temperatures over 400°F wherecontamination is not severe. The flinger acts as a labyrinthseal. High temperature bearings require a greater amount ofdiametral clearance (DC) and a higher temperature lubricant.Consult Rexnord Bearing Products for recommendations.Consult your MB bearing source for price and availability ofany special features.

Examples for ordering:1. Bearing Insert KMB451–716–FFPA2. Mounted Unit KC451–716–FF

The most popular mounted units are pillow blocks. Pillow blocks provide an integral unit to support shaftsparallel to the mounting surface. The casting base has elongated holes for the mounting bolts to provideinterchangeability with other competitive makes as well as ease of adjustment during installation. Self-aligningpillow block assemblies usually do not require shimming at the base becaues self-aligning of the bearing withinthe housing permits enough adjustment.

WIDE 2-BOLT STANDARD DUTY KROWN REGAL CENTRIK-LOKFLANGE UNITSThese flange units incorporate the advantages of foot mounted pillow blocks but are intended for surface mounting, verticalor horizontal, at right angles to the shaft. Bolt holes are spaced for interchangeability with mounting of similar designs.

2-Bolt flange units, like the foot mounted counterparts, are also provided with grease fitting for relubricationpurposes. The bolt hole size as well as spacing is interchangeable with other competitive units. Flange unitsare also used in place of pillow blocks for side mounting without providing brackets or any other type ofstructure.

These MB flange units have been designed to maintain a minimum overall thickness with the smallest possiblestandoff dimension from the mounting face or back of flange to the outboard face of the inner race. Thisminimizes the necessity of extending shaft lengths and provides interchangeability with other competitivemakes.

4-Bolt flange units, like the foot mounted counterparts, are also provided with a grease fitting for relubricationpurposes. The bolt hole size as well as spacing is interchangeable with other competitive units. Flange unitsare also used in place of pillow blocks for side mounting without providing brackets or any other type ofstructure. Units are also available in the same series and bore sizes as pillow blocks.

These MB flange units have been designed to maintain a minimum overall thickness with the smallest possiblestandoff dimension from the mounting face or back of flange to the outboard face of the inner race. Thisminimizes the necessity of extending shaft lengths and provides interchangeability with other competitive makes.

MB bearings provide design and performance featuresdeveloped by decades of experience in supplying precisionball bearing inserts for other major mounted bearingmanufacturers and complete mounted units to machinery andequipment manufacturers. They are priced competitively tobearings of comparable construction.

In addition to sound basic design and construction, specialfeatures minimize the three most common causes ofpremature bearing failure…loosening of bearings on rotatingshafts, entrance of contaminants or loss of lubricant due toseal failure and insufficient housing strength.

Standard duty and medium duty foot-mounted pillow blocks,flange units, take-up blocks and hanger bearings catalogedin the following pages are available from stock. For othersizes, mountings or special requirements to fit yourapplications, please consult the Rexnord Bearing Products.

MOUNTED BALL BEARINGS designed for long life and precisionperformance.

Concentric setscrew shaft locking device

The MB method of fastening the bearing inner race to theshaft provides substantial improvement in holding powercompared to eccentric locking collars and even greaterimprovement over 120 set screw positioning, over-collars andother types of locking arrangement.

Combination seal-flinger system

Optimum protection from loss of lubricant and entrance ofdirt and contaminants is achieved with positive lip-typecontact seals. The resulting longer seal life extends bearinglife significantly.

Rugged, one-piece cast iron housing

Housings are designed to withstand bearing load ratings,external vibration and shock. Foot mounted pillow block boltholes are elongated for easy installation and adjustment.

Spherically-seated bearing insert with anti-rotation device

The spherical fit between the outer race O.D. and I.D. of theblock is precisely controlled for easy shaft alignment. Theanti-rotation device is permanently installed in the bearinginsert O.D. It engages one of the housing insertion slots,preventing outer race creep and wear of housing. There is nodanger of losing a separable pin during field replacement ofbearings and no danger of preloading the bearing as ispossible in other designs where a lube fitting is tightenedagainst a locking pin.

MB concentric setscrew precision mounted ball bearingsfeature a concentric setscrew shaft locking device, resultingin a great improvement in the holding power (lockingefficiency). Field experience shows substantial improvementin holding power when compared to eccentric locking collarsand even greater improvement in locking efficiency whencompared to 120° set screw positioning and other types oflocking arrangements.

The locking set screws are located at a 90° angularrelationship, rather than the traditional 120°.

A force diagram showing the 120° comparison of the lockingcharacteristics of the old 120 set screw spacing and the 90°shaft locking device, superimposed on an end view of theinner ring, provides a more graphic illustration of the reasonfor the locking improvement. The force diagrams arearranged with an assumed 1,000 pound normal forcebetween each of the set screws and the shaft. If each ofthese forces is resolved into its horizontal and verticalcomponents, as shown in the view, it is seen that theeffectiveness of the two horizontal components is lostbecause they cancel. The two vertical components areadditive, resulting in a force between the shaft and the innerring bore at the side opposite the bisector of the anglebetween the two set screws, equal to the sum of the twovertical components.

When the setscrew angle is at 90°, the horizontal and verticalload vectors are equalized. This optimization providessufficient holding power to the shaft seat while controlling ringdistortion. The results are a bearing that operated smoothlywhile achieving prolong shaft seat mounting tightness.

The positioning of the set screws has the further advantageof simplifying the set screw locking procedure. Rather thanhaving to rotate the shaft (and other heavy componentsattached to it) through a large angle to alternatively tightenthe set screws, the 90° locking device requires little or nomovement of the shaft, to insure proper tightening. This isespecially valuable where surrounding installationcomponents limit maneuverability. In this type of application itcan save installation time as well as assuring properassembly.

Standard sealing arrangementsStandard steel clad Type N single lip seals have a usefultemperature range of –40°F to +225°F and can withstandtemperatures of 250°F for intermittent service. Specialsealing arrangements are available for higher temperaturesand “free-running” or special contamination resistance.

Special optional sealing arranagmentsSuffix-MHFF indicates flingers both sides. This provides asealed, “free-running” bearing with heat shield protection. It issatisfactory for temperatures from –40°F to +225°F.

Rexnord Bearing Products must be consulted regardingavailability of any of these optional sealing configurations.

Examples for ordering:1. Bearing Insert MB251–716–MHFFPA2. Mounted Unit C251–716–MHFF

High temperatures ball bearing inserts andhoused unitsMounted ball bearings and MB25, MB35 and ER seriesinserts are available for high temperature applications up to400°F. The “E1” package provides the following features.

1. Extra Internal Diametral Clearance (DC) based on a200°F temperature differential between inner and outerraces, compensates for the inner race expanding at afaster rate than the outer race and will avoid preloading ofthe bearings.

2. Steel Retainer (Cage) – 2 piece riveted construction.

3. High Temperature Lubrication – prelubricated with a No. 2consistency bentone-base grease with petroleum oil.When operated near upper limit, (400°F to 450°F) dailyrelubrication is required.

4. Viton Seals withstand temperatures to 400°F.

Examples for ordering:1. Bearing Insert MB251–716–E1PA2. Mounted Unit C251–716–E1

Free running applications and applicationsabove 400°FSealing options such as –FF (flingers only) for “free running”applications and/or temperatures over 400°F wherecontamination is not severe. The flinger acts as a labyrinthseal. High temperature bearings require a greater amount ofdiametral clearance (DC) and a higher temperature lubricant.Consult Rexnord Bearing Products for recommendations.Consult your MB bearing source for price and availability ofany special features.

The most popular mounted units are pillow blocks. Pillow blocks provide an integral unit to support shaftsparallel to the mounting surface. The casting base has elongated holes for the mounting bolts to provideinterchangeability with other competitive makes as well as ease of adjustment during installation. Self-aligningpillow block assemblies usually do not require shimming at the base because self-aligning of the bearing withinthe housing permits enough adjustment.

2-BOLT STANDARD DUTY FLANGE UNITSThese flange units incorporate the advantages of foot mounted pillow blocks, but are intended for surface mounting, verticalor horizontal, at right angles to the shaft. Bolt holes are spaced for interchangeability with mountings of similar designs.

2-Bolt flange units, like the foot mounted counterparts, are also provided with a grease fitting for relubricationpurposes. The bolt hole size as well as spacing is interchangeable with other competitive units. Flange unitsare used in place of pillow blocks for side mounting without providing brackets or any other type of structure.

All MB flange units have been designed to maintain a minimum overall thickness with the smallest possiblestandoff dimension from the mounting face or back of flange to the outboard face of the inner race. Thisminimizes the necssity of extending shaft lengths and provides interchangeability with other competitive makes.

4-BOLT STANDARD DUTY FLANGE UNITSThese flange units incorporate the advantages of foot mounted pillow blocks, but are intended for surface mounting, verticalor horizontal, at right angles to the shaft. Bolt holes are spaced for interchangeability with mountings of similar designs.

Piloted flange units provide an accurately machined piloted diameter adjacent to the mounting face to positionthe unit in a close-fitting bore in the mounting surface. This procedure accurately locates the bearing and shaftwithout further adjustment or alignment. Typical include machine builders and manufactures of equipmentwhere the supporting side members are line bored to receive the piloted extension at the rear of the flange unit.

Take-up units provide support where shaft adjustment and belt tightening devices or conveyor take-up pulleysare required. The take-up units slide in added-on frames or frames that are an integral part of the equipmentand a screw or nut adjusts the bearing position.

Adjustment is usually manual, but modifications include adjustments by air cylinders or springs for constanttension. Each shaft usually requires two frames and a typical installation would be a belt conveyor. Take-upunits serve as a tensioning divide compensating for belt stretch and, by adjusting only one side, the belt can bepositioned to run on center.


54

The “T” Frame is a uniquely designed module used as a conveyor belt takeup. Used in pairs, it acts as a belttensioner as well as a belt trainer. They use standard Rexnord Bearing Products pillow blocks or tapped basepillow blocks. Threaded internal adjuster is totally enclosed and is protected against product build-up, rust,corrosion or thread damage. Adjuster tube acts as a bulit-in lubricant reservoir. Available in powder coated mildsteel, or 304 stainless steel. Quick-Release method are also available for fast belt change over or clean up.

RUBBER MOUNTED FLANGE UNITSThe rubber mounted bearing insert utilizes an oil resistent, conductive type, rubber adapter which is firmlysupported circumferentially by the stamped steel 2-bolt mounting. The conductive rubber adapter is intended toalleviate electrical static charge build-up often encountered in some air moving equipment applications. Therubber supported bearing insert provides vibration dampening, which aids considerably in reducing noise level.These units are intended primarily for any light duty applications, such as fans, or blowers and are particularlywell suited for heating, air conditioning and ventilating equipment where “quiet” installations are desireable. Thiswould include any applications where any vibration or noise amplified by connecting duct work would beconsidered very objectionable.

The rubber mounted flange units are available in standard shaft sizes with the bolt hole size and spacinginterchangeable with other competitive units. This does not mean the units are interchangeable in all respectswith competition, but can be considered interchangeable in most instances. The units should be thoroughlycompared if complete dimensional interchangeabiilty is essential.

ER TYPE BALL BEARING INSERTS

ER SERIES HOUSING FITSfor bearings with Concentric Setscrew or CENTRIK-LOK Locking Devices

ER type bearing inserts are commonly used in mounted bearing assemblies. The bearings have basicstandard metric ball bearing dimensions with the exception of widths and the inch size bore of the inner ring.Because of the metric ball bearing basis of design and sizing, the ball complement (the number and size) for agiven size bearing is comparable with other manufacturers.

The ER type insert is designed for set screw locking to the shaft, with the bearing mounted in the customershousing. It incorporates standard seals and comes with a O.D. mounted snap ring for axial location, eliminatinghousing counterboring. ER series bearings are intended for rigid mounting, as the bearings have a cylindricalO.D. and not the spherical O.D. of standard insert bearings.

The fit selections given will serve as a guide for the majority of applications where the bearings are subjectedto normal loads and other normal operating conditions. When bearings are subjected to very heavy or vibratoryloads, it may be necessary to employ shaft and housing fits tighter than standard. The same applies if shafts orhousings of soft metal or those not having smoothly ground bearing seats (i.e., the smoothness ordinarilyassociated with ground or reamed bores) are used.

The bearing bore is made so that a sliding fit is produced on the shaft. For best results, a ground shaft shouldbe used to obtain a snug fit. A light press fit is advisable for heavy loads or where dynamic balance isimportant. The following tolerances are recommended for nominal shaft diamters:

These recommended shaft tolerances are for bearings applied under the load and speed conditions listed inthe load rating tables. Consult Rexnord Bearing Products for extreme or special operating conditions.

Furthermore, if speeds are abnormally high, it may be necessary to maintain shaft and housing fits other thanthose shown in tables. Consult Rexnord Bearing Products engineering department for recommendation on anyabnormal conditions.

STAMPED STEEL PILLOW BLOCKS AND FLANGETTESStamped steel pillow blocks, consisting of a two piece stamped steel housing with a spherical bearing seat tomatch the spherical radius ground on the bearing O.D. for light duty applications, provide the advantages of aball bearing construction in an economical low cost unit. The base-to-shaft centerline height and bolt holespace of these units make them readily interchangeable with many standard mounting on the market.

All the stamped steel mounted units are easily adaptable to a variety of applications. The units are often usedvery successfully in application where the unit is selected for a given shaft size, for economic reasons, ratherthan for load rating. However, it should also be stressed that consideration should be given to the load ratingand the unit should not be selected merely for the shaft size. The load rating is based on the strength of thespecific stamped steel mounting rather than the bearing insert.

It is important that the inner ring set screws be tightened securely against the shaft before the stampedhousing is attached (fastened) to the mounting surface. The self aligning feature of the stamping clamps thebearing O.D. when the mounting bolts are tightened and makes any additional alignment of the bearing insertwithin the mounting impractical.

Stamped steel flanges or flangettes consist of two interchangeable pressed steel flanges with spherical insidesurfaces to form a mating contour to accomodate the spherical O.D. of the bearing insert. These are usuallymade in two, three and four bolt designs with standard mounting dimensions, or on a special basis to fitspecific applications. They are low cost units for light duty and moderate speed applications.
