ABSTRACT:
A bearing with a ball contact with a raceway groove of one of an outer ring and an inner ring at one point and the other at two points. The surface of the ball and the surface of the race of the outer ring and the race of the inner ring were provided with a phosphorus-based modified layer. The ball bearing is at a rotary speed as high as not lower than 70 m/s as calculated in terms of V and a load as small as not greater than 0.05 as calculated in terms of Pr/Cr supposing that the dynamic equivalent radial load is Pr, the basic dynamic rated load is Cr, one of the inner ring and the outer ring is a driving ring and the slip rate of the ball to the one of the inner ring and the outer ring as a driving ring is V.
