TOUGH AS THEY COME!

DURABLE CAST IRON SPLIT HOUSINGSThe user's major cost is not always the original cost of the bearing, but the installation time required to putit into productive operation. RPB cast iron split housings have a ribbed design for added strength.Cap bolts are Grade 5 minimum width 60,000 psi tensile strength.

• Quickest replacement of bearing insertwhenever change out is needed.

• Once installed, the housing base alwaysremains aligned with the shaft... doesn'tneed to be disturbed.

• Reduce downtime, replacement costs.

• Guide pins in the housing base and matingholes in the cap help eliminate error duringreplacement. Guide pins ensure the properorientation of the top housing - in the samedirection in which it was machined at thefactory - for optimum fitup and assembly.

UNITIZED REPLACEABLECARTRIDGE INSERTSThe heart of the RPB Series bearing is the one-piece,self-aligning cartridge with integral seals and doublelocking collars. This represents a significant achievementin engineering and manufacture. Each cartridge fits intoany RPB housing style for maximum control ofinventory and easy replacement.

• Constructed from two precision ground outer race halves,matched to a Timken® bearing inner race assembly - foroptimum end play control.

• Outer race halves are then carefully processed to form one-piece unit.

• The cartridge unit is sealed and packed with grease and is a ready-to-useself-contained insert - for assembly in SEALMASTER housings or as field replacement bearings.

• Optimum factory-controlled end play eliminates use of shims, snap rings, machined shoulders andlock nuts, ensures proper roller contact with the races reducing edge loading, eliminates fieldadjustment problems found with other designs.

UNIQUE...UNCHALLENGED...THE UNDISPUTED LEADERIN QUALITY AND VALUE-ADDED ADVANTAGES


100


• Inner race, rollers and cage assembliesmanufactured by Timken®, with over 80years’ experience in this type of bearing..tapered rollers provide true rollingmotion with minimum friction.

• Inner race and rollers of case-hardened,alloy steel - provide long fatigue life underheavy loads.

• Ensures optimum performanceunder combined radial and thrustloads. Can carry high thrust loadswhere spherical bearings in the sametype of application may be limited.

TIMKEN® TAPERED ROLLER BEARINGSOffer rugged design, proven performance and outstanding reliability in a diversity of heavy-duty applications...

• Manufactured from through-hardened 52100 steel with aspherical outside diameter; black oxide treated for corrosionprotection.

• Precision fit with the spherical seat in the housing... provideseven load distribution, allows full 3o static misalignmentcapability - more than twice the capability of most otherspherical bearings - the 3o self-aligning feature reducesabnormal stress on bearing components andseals...overcomes alignment problems common in rigid typetapered roller bearings with one-piece housings.

ONE-PIECE SPHERICAL OUTER RACE

• Inserted between the mating outer race halves - fits into arecess in the housing top.• Ensures positive lubrication - one of two cartridge lubricationopenings always lines up with the grease fitting.

• Prevents outer race rotation of the cartridge insert; thehardened steel outer race cannot rotate in the housing underload, thus keeping intact the factory-adjusted fit between thehousing and cartridge... the race will not wear away the castiron housing because it is locked in place.

ALIGNMENT PIN

• Same proven design used in SEALMASTER Gold Line BallBearings.• Outer shield rotates with the shaft, creating a flinger actionwhich reduces contaminant build-up. Outer flinger-shieldextends slightly into bearing chamber to churn and break upthe grease flow and direct it back into the rolling elements.

• Effective sealing in dry, dusty or dirty environments - felt actsas a filter, has low friction.• Race mounted seals are not subject to misalignmentdistortion.• Shields are black oxide treated for corrosion protection.

PATENTED FELT LABYRINTH RACE MOUNTED SEALSDirect contaminants away from the sealing surfaces... provide a tight fit to exclude foreign material... haveless drag and less heat generation than radial lip rubber contact seals.

• Cartridge contains two lubrication ports and one relief port...extra lube ports prevent seal damage by venting excesspressure from overgreasing.• Rubber grommet is located in the housing cavity beneath thegrease fitting - lines up with one of the lube ports in thecartridge to direct the grease into the bearing... competitivespherical roller bearings with one-piece outer races aredesigned with a circumferential grease groove and oil hole to

direct grease into the bearing; soap base greases (conformingto NLGI grade #2) can dry out, cake and harden if the bearingis stored for long periods of time or not lubricated frequently.This can obstruct clean grease from entering the bearing andpossibly lead to a premature bearing failure.• The cartridge is designed for universal assembly into anyRPB housing style... can be a major cost-saver where manybearings are used.

POSITIVE LUBRICATION SYSTEMLubrication doesn't have to travel around an annular grease groove - it follows a short path directly into the bearing!

• Consists of an elastomeric rubber sealing element bondedto a steel shield.• Functions well in wet and dirty environments up to 250° F.• Has good chemical resistance properties.

• Race mounted seals are not subject to misalignment distortion.• Shields are black oxide treated for corrosion protection.

• Each collar has 2 setscrews spaced at 120° - providesbalanced three-point contact and symmetrical locking.• Hardened setscrews in a soft collar provide maximum holdingpower in applications involving heavy loads, reversing andvibration... a special coating on the setscrews reduces thefriction when inserting and torquing them into the lock collars,resulting in more holding power.

• Double extended inner races provide excellent shaft support -load is distributed evenly over a wide area.• Collars also serve as 2 extra flingers that rotate with the shaftto repel contaminants away from the seal.• Black oxide treated for added corrosion protection.

SINGLE LIP RACE MOUNTED CONTACT SEALSAvailable on all bearing sizes recommended where moisture conditions prevail...

1. SINGLE LOCKING COLLARSGenerally for applications involving shaft length considerationsor limited space.• Available from stock in bore sizes, 1 3/4" - 3 15/16".• Designated with "A" suffix, e.g. RPBA207-2... see pages 105,108, 109, 115, 117, and 120.

2. CYLINDRICAL CARTRIDGE INSERTSDesigned to mount directly into customer housings and asinserts in expansion RPB housings.• Available from stock in 1 3/4" - 5" bore sizes with felt andcontact seals.• High temperature grease and seals can be supplied onrequest.

3. EXPANSION TWO AND FOUR BOLT PILLOW BLOCKS• Available from stock in bore sizes 1 3/4" - 5".• Total expansion 3/16" - 3/8"... see pages 106, 109 and 111.

4. CAST STEEL PILLOW BLOCKSFor applications requiring greater housing strength than castiron.• Two bolt bases - bore sizes 1 1/2" - 3 1/2"... see page 112.• Four bolt bases - bore sizes 3 15/16" - 5"... see page 112.

5. INDUSTRY INTERCHANGEABILITY• Same bolt centers and base-to-shaft centerline as mostcompetitive one-piece housings. (Metal nameplate attachedsecurely beneath the grease fitting for long-lastingidentification.)• Longer bolt slots permit easy replacement for mostcompetitive brands.• New RPBXT Series has interchangeable shaft-to-centerlinedimensions and bolt hole spacing with the popular 500 SeriesSAF style spherical roller bearing pillow blocks... see pages110 and 111.

D: HIGH TEMPERATURE• High temperature seals and grease - "Nomex" material isused in place of felt where requested for elevated temperatureenvironments...the current high temperature greasestandard is Mobile SHC 460.• Price and delivery of customer lubricants including (OSP)oil saturated polymer can be furnished on request.

For all tough applications...where performance and reliabilitycount... specify SEALMASTERSelf-Aligning RPB Series taperedroller bearings.

Refer to specifications and dimensions on the following pages.

Contact Sealmaster Applications at 630-898-9620.

A: TIGHT HOUSING FITS• Tight housing fit “TF” for vibrating conveyor applications.

Some applications require a tight fit-up between the bearingcartridge O.D. and the housing. Typical applications of thistype are on vibrating conveyors and shaker screens whereeccentric and rotating loads exist. The tight fit-up prevents themovement of the cartridge in the housing. The RPB-TF unitsare shipped from the factory with cap bolts snugged by handand tagged with the proper torque specifications. It is importantto allow the cartridge insert to seat itself properly beforetorquing the capscrews and cap bolts.See pages 140-141 for Vibratory Application information.

B: CUSTOM HOUSINGSGenerally require pattern and tooling charges - price anddelivery furnished on request.• Tapped base pillow blocks.• Housing styles to match competitive base-to- centerline andbolt spacing dimensions.• Ductile iron or steel.

C: REDUCED END PLAYRequires an application review by our engineering department.Ask our Engineers for additional information.

ERPB Series Expansion Type Pillow Blocks...Two Bolt Base






Four Bolt BaseTwo Bolt Base

The ERPB series of expansion roller bearing pillow blocks is designed for use in conjunction with the RPB and RPBA series where a “floating” or expansion typeblock is required.While two fixed units mounted on one shaft are normally satisfactory for most applications, expansion units are recommended:

1. Where bearing supports are not rigid.2. Where significant temperature differentials are expected between shafts and mounting structures.3. Where shaft is unusually long.

At least one bearing on each shaft must be of the fixed type.

RPBXT Series Bearings Eliminate Assembly and Adjustment at Installation.When users replace 500 series SAF style pillow blocks with the New SEALMASTER RPBXT, installation is easier and faster. Here’s why:

That are a Dimensional Interchange with SAF... BearingsThe RPBXT/ERPBXT lines offer users significantly reduced costs for assembly and installation. This line of four-bolt nonexpansion (RPBXT) andexpansion (ERPBXT) roller bearing pillow blocks is available in bore sizes from 2 1/4” through 5”. It offers users a factory assembled, self-aligning,mounted tapered roller bearing unit that interchanges shaft-to-centerline and bolt hole spacing with the popular 500 series SAF style spherical rollerbearing pillow blocks.

RPBXT and ERPBXTMounted Roller Bearings...The Time-Savers...

TOUGHAS THEY COME!

Misalignment is a Tough Challenge for Bearings and Seals... RPBXT Handles it Better!

• RPBXT units are fully-assembled, sealed andfactory lubricated, ready to install right onto the shaftwhen they’re received. You save time and money.

• At installation, the RPBXT unit is simply secured to theshaft with concentric double locking collars, each ofwhich has two setscrews at 120°, providing balancedthree-point contact and symmetrical locking.

• SAF Units require complete assembly: The bearing,housing, seals, adapter nut, sleeve and washer are allshipped loose. The user must assemble all components,adjust bearing clearances during assembly and lubricate thebearing unit.

• SAF Units are locked to the shaft with an adapter sleeve andtightened with a locknut/lockwasher assembly.

RPBXT Units SAF Units

RPBXT units have race mounted seals that move with thecartridge insert and are not subjected to shaftmisalignment stress. RPBXT Seals can accommodate upto ± 3° degrees of shaft misalignment stress without lossof seal effectiveness. RPBXT roller bearings offer theuser a wide choice of seals to suit application needsincluding patented labyrinth seals, proven in thousands ofapplications, a single lip contact seal, or the hightemperature (Nomex) seal. Once the lubricant permeatesthe felt (seal), a lower coefficient of friction (reduced drag)and extended operating life result.

SAF style pillow blocks operate successfully inmisaligned conditions up to ± 1 1/2° because thespherical O.D. of the bearing matches the spherical I.D.of the outer race. Thus, misalignment is internal. Theseals however are mounted between the stationaryhousing and the shaft and are subject to movement whenmisaligned. The seals are designed with clearances toallow for the movement therefore reducing theireffectiveness.

TOUGHAS THEY COME!FLANGE UNITS...Sealmaster split housed four-bolt flange unitsare designed for face mounting against verticalor horizontal structures where a miniumamount of machining is required. These flangehousings have machined foot pads on the baseto facilitate installation and removal of doublelocking collar styles. Flange units are availablefrom 1 3/16" to 4 1/2" bore sizes in both singleand double locking collars.

These units can be supplied with a choice ofthree seals; felt, contact and high temperaturenomex. They are strongest when loads areapplied in the thrust direction through themachined face.

Sealmaster split housed piloted flange unitsare commonly used in applications whererotating and eccentric loads are present.Typical applications include vibratingconveyors material handling, construction, andmixers. The combination of flange and pilotfeatures allow them to be integrally mountedin both horizontal and vertical shaftapplications.

PILOTED FLANGE UNITS...

The split housing is designed with a machined pilot extension that provides added support, thusreducing stress on the mounting bolts. Sealmaster piloted flange housings are round and stockedin shaft sizes from 1 3/16" - 5". Units through 4" contain four mounting bolts; sizes 4 7/16" through5" contain six mounting bolts. These units can be supplied with a choice of three seals; felt, contactand high temperature nomex. This series is available with both single and double lock collars.Provisions should be incorporated to facilitate installation and removal of double locking collarstyles.

SEALMASTER RPB-AH Air Handling Roller Bearings...With Enhanced Performance... for the World-Wide HVAC Industry...Roller bearing units forHVAC applications are subjected toa number of unique challenges thatinclude:

1.Running at higher operating speeds.2.Exposure to vibration.3.Running with low noise levels.4.Mounting on fan frames that have reduced

structural mass.

SEALMASTER RPB-AH tapered rollerbearings units are specially-designed withengineering features that address each ofthese challenges, and offer overall enhancedperformance in air handling services. Here areseveral reasons why...

HIGH LOAD CAPACITIES... RPB-AH Tapered rollerbearings offer both high radial as well as high thrustload capacities, or any combination of the two.Spherical roller bearings, on the other hand, are notknown for their thrust capacity, and are generally notselected/specified for vertical shaft applications whichare often encountered in HVAC.

PINNED OUTER RACE PREVENTS ITS ROTATION ...The RPB-AH bearing has a self-aligningcapability of ± 3°. This design is similar inconcept to the proven SEALMASTERball bearing units which utilize aspherical O.D. insert mounted in aspherical I.D. cast iron housing,equipped with a locating pin. Thisanti-rotation pin prevents outer racerotation under load and does not limitthe RPB-AH self-aligning capability.The extensions on the cartridge inserts limitmisalignment to ± 3°.

CUSTOM FIT-UP... Sealmaster engineers havedeveloped a custom fit-up between the bearingcartridge O.D. and the bearing housing specifically forair handling applications. This fit is looser than standardwhich provides lighter misalignment torque. Fan framesare generally light weight which may deflect before thebearing insert adjusts for misalignment in standardunits. This special feature also allows full roller contactwith the races and reduces roller edge loading in thebearing.

**HVAC applications are normally lightly loaded but may require higher speed capability. For these applications consult Sealmaster Engineering for assistance.

DURABLE CAST IRON SPLIT HOUSING - Compact split housing provides quickest replacement of bearinginserts, reduced downtime and replacement costs.

PATENTED FELT LABYRINTH SEALS - Proven design directs contaminants away from sealing surfaces, providesa tight fit to exclude foreign material; once grease permeates the felt there’s a lower coefficient of friction ( or reduceddrag), less heat generation, extended operating life.

EXTENDED INNER RACES - With double locking collars provides a more secure locking system, more holdingpower and greater stability on the shaft.

metric setscrews. All other components andhardware are standard.

SEALMASTER RPB-MSeries Metric Bore BearingsThe RPB-M Series Metric bore bearing is available in the full range of sizes and various mounted bearing stylesas shown in the Table on the opposite page. These metric bearings have the full range of features and benefits ofthe RPB Series self-aligning bearings described in detail on pages 98-103.

Three basic sealing arrangementsare offered for the RPB-M Metric BoreBearing...

Patented Felt Labyrinth Seal...Directs contaminants away from the sealingsurfaces... provides a tight fit to exclude foreignmaterial... has less drag (friction) and less heatgeneration than radial lip contact seals;provides positive sealing for low, medium, andhigh speed operation.

Single Lip Contact Seal...Available in all sizes... recommended wheremoisture conditions prevail... functions well inwet and dirty environments up to 250°F... hasgood chemical resistance properties.

High Temperature Seal...Available extra-cost option where operatingtemperatures are in the 250 - 400°F range;units with these sealing arrangements areprelubricated at the factory with a special hightemperature synthetic lubricant which isnormally satisfactory for the temperature range0f -40°F to +400°F.
