Rolling bearing manufacturing apparatus and method

Abstract

A rolling bearing manufacturing apparatus is used to work the two races of a rolling bearing and then assemble the thus worked outer and inner races together with a plurality of rolling elements into the rolling bearing. The present apparatus comprises an outer race groove working machine 11 for working the outer race of the rolling bearing to thereby form a raceway groove therein, a gauge part 23 for measuring the raceway diameter of the raceway groove of the outer race after the present raceway groove is worked by the outer race groove working machine 11, and an inner race grinding machine 12 which, in accordance with the thus measured raceway diameter, works the raceway groove of the inner race in such a manner that an internal clearance can provide a predetermined constant amount.
