ABSTRACT:
An improved method for retaining a separable bearing race to a inner bearing member and also preventing twisting of the separable race on the spindle. The end face of the separable race over which a portion of the spindle is deformed as a retaining bead is deliberately ground so as to be slightly inclined to, rather than square to, the spindle-race co axis. As a consequence, any force tending to twist the race on the spindle about the axis creates a strong axial wedging action between the tilted bearing end face and conforming bead surface, acting to prevent the race from twisting. The only change in the processing and assembly of the race and bearing needed is to set up the race grinding wheel with a slight incline.
