Ideal choice when shaft is not practical to use as inner raceway.
Provided in inch (IR, IRA) nominal dimensions for use with inch series drawn cup needle bearings.
Designed to be wider than matching drawn cup needle bearing.
Optional centralized lubrication groove (bore) and thru-hole available - specify when orsering.
Designed to provide a loose transition fit on the shaft and should be axially clamped against a sholder.
If the tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring O.D. must not exceed the raceway diameter for matching drawn cup bearing after being mounted on the shaft.
After mounting , if O.D. of inner ring exceeds required raceway diameter for matching bearing, ring should be grounded to proper diameter while mounted on shaft.
