Abstract
Abstract A bearing assembly is disclosed which includes a ball bearing, a cover secured to the outer race of the bearing, and a synthetic resin molded member formed on the cover by injection molding. This bearing design reduces the necessity of machining substantially and is therefore suited for mass production.
