The motion of revolving cages guided by the bearing rings is measured in the three dimensional directions under various experimental conditions by the non-contacting displacement vibrometer and is measured in the revolving direction by the stroboscope. The running cages oscillate in the three dimensional directions and in the revolving direction, especially they have very large amplitude and parallel oscillation in the axial direction. The oscillations of the integral numbers' frequencies, 1, 2, 3, …times as large as the revolving speed of the cages, are usually contained with in the motion. It seems that oscillations of the cages are brought about by contacting conditions between balls and cage pockets in the running. The amplitude of oscillations are not so subjected to the effect of revolving speed, loading directions and magnitude of load.
