A New Strengthening-Polishing Bearings Equipment Based on the Anti-fatigue Manufacturing Technology

Aimed to eliminate the harmful residual tensile stress produced on the surface of bearing ring in the conventional bearing processing and join the automatically strengthen and polished technology together, the paper provide a set of new strengthening-polishing bearings equipment, designed to effectively improve the bearing surface's quality and produce the surface residual stress which can extend the bearing's fatigue life. The prototype, based on the pre-theoretical design, has been successfully developed, and now is in field testing.
