Radial Internal Clearance - Bearing Works

Radial Internal Clearance. Internal clearance is the play within a ball bearing. It is the geometrical clearance between the inner ring, outer ring and ball. It is a critical factor in bearing selection that will directly impact bearing life. It is often overlooked, particularly as to how it is reduced by interference fits.

Why are your bearings C3? - Bearing King

C3 means the bearing has more clearance than standard. For example we may use C3 clearance on bearings where a cold start up appliion my cause the balls to heat up quickly, the heat needs to go somewhere. Some of the heat gets passed through the outer race to the housing and the inner race to the shaft, this causes expansion which closes up

Vibration Analysis Dictionary: Terms - Mobius Institute

If the vibration spectrum of a machine shows a high amplitude of the FT, it does not mean the bearing has a bad cage, but rather means that one of the rollers is cracked or otherwise deformed. This causes a vibration component to occur each time the roller enters the load zone of the bearing, which is at each revolution of the cage, giving rise to a vibration at that rate.
