ABSTRACT:
A rolling bearing suitable for use in a high temperature atmosphere is provided.
The bearing is partly or entirely made of a ceramic material with at least its inner ring being made of a ceramic material so as to improve the rotational and antiabrasive efficiencies thereof in a high temperature operating condition.
Further, in order to prevent both chamfered ends of the inner ring from cracking or chipping, the inner peripheral surface is crowned to have a Lundberg profile thereby avoiding a local concentration of stress on the inner ring.
