An experimental apparatus and measuring system has been developed for the measurement of actual ball motions in thrust ball bearings. In the apparatus, a representative point on the ball, a magnetic pole of a magnetized ball, is traced by Hall elements arranged on the orthogonal three axes. With the apparatus, an experimental investigation of ball motions in the thrust ball bearing #51308 was carried out under various axial load conditions. Experimental results were plotted in space and projected onto a plane, illustrating a clear view of ball motions. Ball behavior in operation under various load conditions were compared each other and discussed from the viewpoint of stability of ball rotation. It was inferred that the ball rotary axis was not constant at low axial loads below 149N and it was almost constantly pointing radially at axial loads over 149N. The results demonstrated complicated ball motions under low loads, offering fundamental knowledge on the minimum axial load required for the ball without generating slip and slide.
