Suitable bearing race material is formed into bar stock having a longitudinally oriented grain structure and having a cross-section corresponding to the cross-section of the prospective bearing race. From the thus-shaped bar stock are cut a plurality of pieces whose combined lengths substantially equal the circumferential length of the prospective bearing race. These pieces are then bent into circularly arcuate segments having curvatures corresponding to that of the prospective bearing race and having ends configured to fit one another. These segments are then aligned end-to-end in an annular path and welded together into an annular body which is then hardened and ground. This bar stock is provided with an inclined side surface which, for an outer race, becomes the inner surface of the segment, and for an inner race becomes the outer surface of the segment, in each instance constituting the roller path.
