ABSTRACT:
A plastic bearing is provided, as well as a method of fabricating these bearings, in which a number of strands of expanded polytetrafluoroethylene fibers are woven about a cylindrical mandrel to form a fabric about this mold surface. The fabric is then impregnated with a hardenable plastic. The plastic is hardened and the bearing is removed from the mold surface. The resulting plastic bearing has greatly improved wear resistance which permits new applications.
