摘要

In the ball arrangement method of the ball bearing, a ball placing step of loading a plurality of balls in one region along the circumferential direction of the annular space formed between the inner ring and the outer ring, and the one region of the annular space A flow stop step for disposing a flow stop jig that holds the loaded balls in the one region on the outer side in the circumferential direction, and a state in which the flow stop jig is disposed in the annular space. While removing the stop jig from the annular space, the tips of a plurality of working arrows protruding in accordance with the number of the balls are sequentially inserted in the axial direction between the plurality of balls, The ball division process arranged at equal intervals in the circumferential direction is performed in this order.
