摘要： A rolling bearing is disclosed of which the lifespan is increased by reducing brittle flaking and impression-induced flaking on the raceways of inner and outer races and the rolling elements. Steel containing 1.80-1.89% by weight of chrome (brittle flaking-resistant steel) is subjected to carbonitriding and then to hardening and tempering. The chrome reduces generation of white layers which are aggregates of carbon, thus reducing brittle flaking on e.g. the raceways (1a, 4a) due to the white layers. A residual austenite region (5) that forms when the steel is hardened and tempered increases toughness of the steel surface, thus reducing impression-induced flaking due to foreign matter such as wear dust. By reducing both brittle flaking and impression-induced flaking, it is possible to extend the lifespan of the bearing, and reduce maintenance cost such as the cost for changing lubricating oil.
