Torrington NEEDLE BEARING INNER RACES TOR IR-88
Where it becomes impractical to meet the shaft raceway design requirements (hardness, case depth, surface finish, etc.) outlined in the engineering section, standard inner rings for drawn cup bearings are available. Inner rings for drawn cup bearings are designed to be a loose transition fit on the shaft and should be clamped against a shoulder. If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring OD as mounted, must not exceed the raceway diameters required by the drawn cup bearing for the particular application.

Suitable For Use WithB-126, B-128, J-126, J-128, M-1261, M-1281 Drawn Cup Needle Roller Bearing
- Ideal choice when shaft is not practical to use as inner raceway
- Designed to meet established inch tolerances
- Designed to be wider than matching drawn cup bearing
- Maximum shaft fillet radius cannot exceed inner ring bore chamfer
- Designed to provide a loose transition fit on the shaft and should be axially clamped against a shoulder
- If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring OD must not exceed the raceway diameter for the matching drawn cup bearing after being mounted on the shaft
- After mounting, if OD of inner ring exceeds the required raceway diameter for matching bearing, ring should be ground to proper diameter while mounted to shaft

Sealmaster 1-1/2"-ID 2-BOLT TRB PILLOW BLOCKS SEA RPB-108-2
The Sealmaster® RPB mounted tapered roller bearings are a dimensionally interchangeable upgrade from competitive type E bearings. The exclusive features include unitized replaceable inserts, self-aligning capability and split housing. They also include the Sealmaster® alignment pin. This provides a direct path for lubrication into the bearing and helps to prevent outer race rotation. The Sealmaster® RPB is available with two traditional setscrew locking collars for easy installation. The felt seal with flinger provide a good balance between contaminant entry, grease retention and friction. Depending on application requirements, these bearings are available in both inch and metric. They provide a wide variety of housing, sealing and lubrication options.
