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.

The spherical surface inspection equipment also includes sphere-to-be-examined drive member which retains the sphere such that its center is brought in alignment with the second focal point, and which rotates the sphere about the axis of rotation along a specific half of the meridian included between the poles on the surface of the sphere opposite to the predetermined inner surface of the curved-surface mirror; and surface nature determination member which limits the light reflected from the sphere to only the light reflected from an area corresponding to a predetermined width between the half of the specific meridian included between the poles and detects the thus-limited reflected light through use of at least one photodiode; and which determines the nature of the surface of the sphere according to the result of such detection.
