Recently, the sound and vibration generated by rolling bearings rotating at high speeds and subject to large radial loads have been frequently discussed and are thought to be generated by rolling balls cllision with retainer wall. In this study, the experimental behavior for the ball revolution is observed by using a system that the test bearing of inner and outer ring are independently rotated on contra-direction respectively, and its situation is recorded by VTR. The main conclusions are : (1) When the retainer is removed, the balls in the bearing are aligned up along the center of the loading area in the lead. (2) The balls in the loading area do not move within the retainer pocket. However, the balls in the unloading area move considerably within the retainer pocket.
