Abstract

PURPOSE:To maintain good lubrication and prevent escape of a crown-shaped retainer from a bearing body by providing a self-lubricating agent at least a portion of each pocket of the retainer contacting each ball. CONSTITUTION:A crown-shaped retainer 10 is formed of metal such as steel or iron. The retainer 10 is formed with pockets 5 retaining balls. A self- lubricating film 11 formed of highmolecular composite material such as PTFE is coated on a ball sliding surface of each pocket 5. In a self-lubricating deep groove ball bearing including the retainer 10, good lubrication to sliding contact of each ball is maintained by the self-lubricating film 11. Moreover, as claws 12 of the retainer 10 are formed of metal, there is no possibility of breakage or the like due to an external force such as vibration and shock, and escape of the retainer 10 is prevented. Accordingly, a life of the bearing may be extended, and the reliability may be improved.
