ABSTRACT:
A ball bearing and method for making same in which at least one of the inner and outer bearing races is comprised of sheet metal and formed to include at least one circumferentially disposed ball member receiving groove therein. The sheet metal race is formed by a plurality of separate steps which may be conveniently sequentially performed in a single progressive type die. In forming the sheet metal race, a generally flat bearing race blank is formed into a cylindrical configuration with the opposite ends thereof brought into a close spaced relationship with each other so as to form a slot-like opening therebetween. During the final stages of such forming, a squeezing or working force is applied circumferentially to the race in order to place the race into the plastic range to thereby eliminate undesired spring back or separation between the closely spaced ends.
