The motion of revolving solid cages was measured in radial (horizontal and vertical) and axial directions under various experimental conditions by the noncontacting displacement vibrometer utilizing variations of self-inductance. Out of the experimental results, it is found that the motion was considerably affected by the coefficient of viscosity of lubricating oil, by the conditions of lubrication between balls and pockets and by the conditions of motion of balls under the loading, that is, by the condition whether the balls have slips or not while balls are rotating and revolving. And the oscillations of integral number's frequency, 1, 2, 3, ...... tims as large as the revolving speed of the cage, are usually contained within the motion. As the frequencies have no relation to the number of balls and the rotating speed of the inner ring, the author presumed that the oscillations of the cage were brougt about by contacting conditions between balls and cage pockets.
