ABSTRACT:
A flat strip of metal is formed to provide a depressed center relief portion between two edge portions. Depressions are formed in the two edge portions and center slots are pierced across the center relief portion such that roller receiving slots are formed with slot end depressions at both ends of the roller receiving slots. The partially formed bearing cage is then formed into a circular hoop such that the edge portions form rings at the axial ends of the circular hoop. The resulting roller bearing cage of the present invention may also be formed by other methods.
