Abstract

The non repetitive run-out (NRRO) of rotational frequency of the cage is mainly caused by the diameter differences of balls contained in one bearing. In addition, it was known that the unequal orbital intervals of balls could influence the NRRO of rotational frequency of the cage. But there were few quantitative studies about this. In this paper, we investigated the influence of the unequal orbital intervals of balls on the NRRO of cage rotation by pulling out balls intentionally. It was clarified that the NRRO of rotational frequency of the cage became large if the difference between orbital intervals of balls was large.
