Features:
- 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
