ABSTRACT:
A bearing which is wear-free and optimal in terms of loading at very high rotational speeds and even in the case of self-aligning bearings with point contact. bearing uses balls made of ceramic and raceways of X 30 Cr Mo N 15-1. A radial clearance of between 0.0005 and 0.0007 times the bore diameter of the inner race is provided. One race may be planar and the other profiled to the balls. The planar race may be slightly convex to the balls or may be conical.
