Rolling contact member, rolling bearing, and method of producing rolling contact member

An outer ring, an inner ring and a ball that are a rolling contact member formed of sintered sialon inexpensive and capable of reliably ensuring sufficient durability, is constituted of a sintered body containing sialon as a main component and having a remainder formed of an impurity, and the outer...

Beschreibung
Zusammenfassung:	An outer ring, an inner ring and a ball that are a rolling contact member formed of sintered sialon inexpensive and capable of reliably ensuring sufficient durability, is constituted of a sintered body containing sialon as a main component and having a remainder formed of an impurity, and the outer ring, the inner ring and the ball have raceway/rolling contact surfaces, i.e., an outer ring raceway surface, an inner ring raceway surface and a ball rolling contact surface included in a portion having an outer ring high density layer, an inner ring high density layer and a ball high density layer higher in density than an inner portion.
