Abstract
A separator for the balls of a ball bearing assembly, especially of the land riding variety which is constructed of two like parts joined together by ultrasonic welding. The separator is provided with generally cylindrical ball receiving pockets. Skis are provided on the circumference of the separator which ride on the lands of the bearing. Each part of the separator is formed with alternating studs and bores, which, when two parts are assembled, the bores receive the opposing studs. The structure is so formed to insure the flow of lubricant to the raceways.
