An investigation was carried out to elucidate the vibration of the outer ring of a ball bearing under a radial load. In this report, the rigid-body natural vibration of the outer ring was studied. The ball bearings were operated at a constant speed under a radial load. The radial vibrations of 13 points on the outer ring were detected by two accelerometers. Analyzing the radial vibrations, we obtained the mode shape of the rigid-body natural vibration of the outer ring. From the experimental results, analysis and considerations, the existence of the rigid-body natural vibration of the outer ring was clarified, and the frequency expression for the rigid-body natural vibration of the outer ring was derived. Moreover, considerable accuracy of the frequency expression was demonstrated.
