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.

A roller bearing cage comprising:
- first and second end rims axially spaced apart with respect to a common axis, each of the end rims having an axially outward end, an axially extending side portion, and a plurality of periodic depressions axially spaced from the outward ends;
- and
- crossbars joining the first and second end rims such that roller receiving slots are formed therebetween, the crossbars having laterally outward portions and a central portion radially offset with respect to the laterally outward portions;
- the crossbars being configured such that a roller within one of the roller receiving slots is retained in the radial directions by engagement with the central portion and with the laterally outward portions;
- the periodic depressions being located between the crossbars, one at each end of the roller receiving slots, such that a roller within one of the roller receiving slots is retained in the axial directions by engagement with the periodic depressions at each end of the roller receiving slot.
