Abstract
A composite bearing race and method for fabrication of such race, the composite bearing race consisting of an assembly of two concentric rings in which the ball grooves are impressed by rolling and which is subjected to a heat treatment. The method of fabricating the composite bearing race includes deformably assembling two concentric rings by rolling to radially embed a ball groove of one ring into the other and subject the composite bearing race formed to heat treatment.
