An angular contact ball bearing has races formed from a case-carburized or carbonitrided steel, preferably a stainless steel, that withstands high forces and high temperatures. The bearing has relatively low osculation ratios to reduce the generation of heat, yet can withstand applied radial loads and the centrifugal forces generated in high speed operation.

1. A high speed bearing for facilitating rotation about an axis, said bearing comprising: an inner race having a raceway that is arcuate in cross-section and presented away from the axis; an outer race surrounding the inner race and having a raceway that is arcuate in cross-section and presented toward the raceway of the inner race; and balls arranged in a row between the races and contacting the raceways of the races; the osculation ratio between the balls and the raceways of both of the races not exceeding about 0.93; the races being formed from a stainless steel containing by weight between about 0.05% and 0.50% carbon and between about 10.0% and 20.0% chromium, the races having hardened cases formed by case-carburizing or carbonitriding, the bearing when operating at one million DN attaining an operating temperature of less than 130.degree.
