Abstract:
The present invention provides a rolling bearing having an excellent corrosion resistance and toughness which can fairly operate at a high rotary speed. At least the inner
race is formed by a titanium alloy, and the rolling elements are formed by ceramics. Alternatively, at least one of the inner race and the outer race is formed by a B type
titanium alloy. The percent cold working of the B type titanium alloy is predetermined to not less than 20% or a range of from 5 to 20%. The cold working is followed by shot
peening. Further, the surface hardness Hv is predetermined to not less than 600. The volumetric ratio of residual B phase in the B type titanium alloy is predetermined to a
range of from 30 to 80%.
