RETAINER FOR BEARING

摘要

A retainer for a bearing, which is formed by the use of a resin composition comprising a polyphenylene sulfide and a second resin having a deflection temperature under a load of 1.8 MPa being higher than that of polyphenylene sulfide. The retainer exhibits high heat resistance, chemical resistance, oil resistance, strength at a high temperature, and the like, being comparable to those of a conventional retainer for a bearing made of polyether ether ketone and further exhibits higher accuracy in dimension and shape and can be produced at a lower cost, as compared to a retainer for a bearing made of polyether ether ketone. It is preferred that the above second resin is a resin having a flexural modulus higher than that of polyphenylene sulfide and that a resin composition contains carbon fiber as a reinforcing fiber.
