Abstract
A method for manufacturing ball bearing retainers by forming material into a helical coil consisting of a plurality of coils, then severing a coil of the helical coil to form a split ring, the severed ends overlapping one another. The split ring is then pressed to form a ball pocket opposite the overlapping severed ends. The remaining ball pockets are formed by successively pressing the split ring forming a pair of ball pockets, each ball pocket being adjacent a previously formed ball pocket.
