ABSTRACT:
An unground ball bearing is manufactured by forming a straight-sided cup shaped outer race having an aperture in the base and a radially inwardly extending flange about the periphery of the cup rim. The outer and inner races are heat treated and subjected to a surface finishing step and the ball bearing is subsequently assembled by inserting the balls within the outer race and then snapping the inner race into position within the outer race by forcing it past the flange on the outer race.
