<p>According to the invention, a synthetic resin composition for the manufacture of parts which require a low coefficient of friction for example bearing parts or other sliding parts having a number of desirable properties is provided. The resin composition is made of a fine powder of RBC, CRBC and mixtures of RBC and CRBC dispersed in a synthetic resin. The RBC and /or CRBC fine powder have an average particle diameter of less than 10 mu m, optionally 1 to less than 10 mu m, preferably 1 mu m to 5 mu m. Desirably the weight percent of the RBC and/or CRBC is from 10% to 70% preferably from 30% to 70% of the entire composition and is uniformly dispersed in the resin. In another aspect of the invention, parts desirably having particularly a low coefficient of friction are fabricated according to the invention from the resin composition. The parts can be made molded desirably extrusion or injection molded from the resin composition according to the invention to form for a bearing or portion thereof or other device requiring a low coefficient of friction. The fabricated products are desirable for use with or without lubrication. The resulting products have a desirable low coefficient of friction improved durability, mechanical strength, and lubricating oil retention. <IMAGE></p> |
