Abstract:
A deep-grooved ball bearing including a rolling contact member formed of a sintered β-sialon inexpensive and capable of reliably ensuring sufficient durability includes an outer ring and an inner ring, and a plurality of balls arranged in contact with the outer ring and the inner ring on an annular raceway. The ball is configured of a sintered body that contains as a main component a β-sialon represented by a compositional formula of Si6-zAlzOzN8-z and satisfying 0.1≦z≦3.5 and has a remainder formed of an impurity.
