Abstract
A rolling bearing to be used in molten metal provides inner and outer races, a plurality of rolling elements and a cage, in which a solid lubricant is exposed at least in contact surfaces between the cage and the plurality of rolling elements, and further in which the solid lubricant is exposed also in contact surfaces between the cage and the inner and outer races. The cage is formed of a material having specific gravity of 0.8 to 1.2 with respect to the molten metal. In the rolling bearing, the wear resistance of the inner and outer races, the rolling elements and the cage can be improved.
