Polymeric lubricant packed bearing and method of producing the same

摘要

A film (6) composed of grease (or a film (8) composed of a thickener for grease) is formed on a portion of the surface of each of components constituting the bearing, the portion being opposed to a polymeric lubricant (7), whereby the sliding frictional resistance between the bearing components and the polymeric lubricant (7) is reduced. In the formation of the grease film (6) (or the film (8) composed of a thickener for grease), a method is employed in which the assembled bearing in which the grease film (6) has not yet been shaped immersed into a liquid which is obtained by diluting the grease (the thickener for grease) with a solvent, and the solvent is then dried, whereby the grease film (6) (or the film (8) composed of a thickener for grease) having a uniform thickness can formed with high reproducibility. <IMAGE>
