摘要： A revolution speed of balls 8, 8 constituting the outer side row is sensed by a revolution speed sensor 24. Also, a rotation speed of a hub 1a is sensed by a rotation speed sensor 25. A speed ratio as a ratio between a revolution speed and the rotation speed is calculated based on a sensed signal of both sensors 24, 25. When the axial load is changed and then the contact angles of the balls 8, 8 are changed, the revolution speed is changed and in turn the speed ratio is changed. Therefore, the axial load is calculated based on a change of the speed ratio.Accordingly, the configurations that can be manufactured at a low cost and is able to sense the axial load applied between the hub 1a and the outer ring 4a can be realized.
