Abstract

Abstract The optimal procedure for the forming of roller-bearing races has been investigated and developed, the combined forward and backward warm-extrusion of the both inner and outer races with a ring preform being found to be the most efficient. A new method of making a ring perform from a cylindrical billet by combined upsetting and piercing has been discovered.
