PROBLEM TO BE SOLVED: To achieve a rolling bearing in which damage, such as early exfoliation, is unlikely to occur on an outer ring track 6, an inner ring track 7, and the raceway surfaces of rolling elements 8, 8 constituting rolling contact parts, and which is capable of suppressing a creep phenomenon between an outer ring 4 and a counterpart member.SOLUTION: In the rolling bearing comprising an outer ring having an outer ring track on the inner circumferential surface, an inner ring having an inner ring track on the outer circumferential surface, and a plurality of rolling elements rotatably provided between the outer ring track and the inner ring track, and used by internally fitting and supporting the outer ring on a fixed portion and externally fitting and supporting the inner ring on a rotating portion, if the minimum thickness of the portion where the outer ring track is provided at the center part in the axial direction of the outer ring is h, and the diameter of each of the rolling elements is Da, 0.4Da≤h≤0.8Da is satisfied and the width of the outer ring is 1.2 Da or more, and to the outer circumference of the outer ring, an elastic body is attached. |
