摘要： A method of manufacturing steel balls for use in a ball bearing comprising an inner steel race or shaft with an inner raceway formed around its outer peripheral surface, an outer steel race with an outer raceway formed around its inner peripheral surface, and the steel balls freely rotatably disposed between the inner raceway and the outer raceway comprises the steps of providing steel balls, quenching the steel balls, preliminarily tempering the steel balls after quenched, rough-polishing the steel balls after preliminarily tempered, surface-hardening the steel balls after rough-polished, tempering the steel balls after surface-hardened, and finish-polishing the steel balls after tempered.
