Abstract:
PROBLEM TO BE SOLVED: To provide a rolling bearing cage capable of improving peeling resistance thereof while eliminating the possibility of elution even in lubricating oil containing sulfur-based additive etc., and to provide a rolling bearing including the same.SOLUTION: A cage 2 holds needle rollers 3 as rolling elements of a needle roller bearing 1. At least on the slide contact surface with the needle rollers 3 and the slide contact surface with the other members in the outer surface of the cage 2, resin coatings are formed. The substrate surface where the resin coatings are each formed has a root-mean-square slope (R▵q) of greater than or equal to 0.1 and smaller than 0.2.SELECTED DRAWING: Figure 2
