Abstract

This paper deals with the non-repetitive run-out (NRRO) of an angular contact ball bearing for machine tools. First, a measuring system for the rotational accuracy of the bearing was developed. Then, the following results were obtained using the developed measuring system. (1) The NRRO of ball cage rotation increased with rotational speed. (2) The influence of form errors in the inner and outer rings on NRRO was small. (3) The influences of form errors in the balls of the bearing and the diameter difference of balls on NRRO were significant.
