摘要： A sealing device for an axle bearing includes a lubricant maintained on sliding contact surfaces, thereby suppressing elevation of torque due to the depletion of grease. A lubricant-adsorbing layer comprises a thickener and a binder. The lubricant comprises a base oil and a thickener. The thickener and the thickener are mutually attracted. A lubricant layer of a prescribed thickness is formed on the lubricant-adsorbing layer. This lubricant layer adheres closely to the lubricant-adsorbing layer making it difficult to separate the lubricant layer from the lubricant-adsorbing layer.

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 μm, optionally 1 to less than 10 μm, preferably 1 μm to 5 μm. 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.
