Abstract
A cage and roller assembly in a hardened thrust bearing race is restrained within the race by heating a plurality of circumferentially widely separated parts of the race lip to soften the lip parts and bending the softened parts over the cage of the cage and roller assembly. An apparatus for assembling the thrust bearing includes a pair of electrodes located to apply a current through the lip to soften the lip and a form punch which is constructed to bend the softened part of the lip over a cage and roller assembly to an acute angle with repect to the rest of the lip.
