Work Hardening of Ball Surfaces

Source

By cold-working the ball surface to a specific degree, it can be made less susceptible to being deformed during testing, transport, and assembly. This paper describes the cold working process and the effect of various process parameters on the resulting residual stress depth patterns. Life tests are described that were carried out with rolling bearings having balls of various cold-working levels. Damage analyses show that the fatigue strength of the ball surface can be reduced by excessive cold working.
