PROBLEM TO BE SOLVED: To reduce the weight, to shorten the machining time, and to reduce cost. SOLUTION: In a bearing composed of rolling members, a rotary shaft 16 having an inner race 16a on which the rolling members are to be rolled, and an outer cylinder 17 having an outer race 17a on which the rolling members are to be rolled, a thin steel pipe material is used for the rotary shaft 16 and the outer cylinder 17, and the inner race 16a and the outer race 17a on which the rolling members are to be rolled are formed on the outer peripheral surface of the rotary shaft and the inner peripheral surface of the outer cylinder by plastic working such as swaging. |
