Abstract
A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage. An annular groove for creep suppression is formed in a fitting surface of the outer ring to be fitted with a mating member (housing) to which the outer ring is to be mounted. An outer ring track groove with which the balls make rolling contact is formed in the inner peripheral surface of the outer ring on the side opposite to the fitting surface. The entire contact ellipse generated when each of the balls and the outer ring track groove contact each other is positioned within the axial range of the outer ring in which the annular groove is formed.
