bearing race manufacturing without grinding

Race (bearing) - Wikipedia

In the case of ball bearings, the bearing has inner and outer races and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point. However, a load on an infinitely small point would ...

General Bearing Handling And Inspection - Reliabilityweb ...

Bearing repair. Small areas of damage on bearing races, and on the contact surface of the rolling elements, can sometimes be repaired by grinding out the loose metal. Any raised or rough areas should be smoothed flat with grinding and polishing tools. Light rust or corrosion should be removed with emery paper (240 – 320 # grit).
