▎ 摘　　要

NOVELTY - The self-repair bearing (100) comprises a base (101) made of a metallic base material and has a cylindrical outer surface (104). A cylindrical inner surface (106) is opposite the cylindrical outer surface, and a central channel (102) is defined by the cylindrical inner surface and extending through the base. A selective transfer material (140) is embedded in the base. The selective transfer material is selected from the group consisting of tin, zinc, copper, iron, lead, palladium, cobalt, titanium dioxide, copper oxide, iron oxide black, zinc oxide, aluminum oxide, zinc dialkyl dithiophosphate (ZDDP), molybdenum disulfide, graphene, silicon nitride, calcium carbonate, magnesium oxide, and serpentine minerals. The serpentine minerals include Aluminium oxide, Calcium oxide, and Ferric oxide. USE - Self-repair bearing. ADVANTAGE - The selective transfer material transferred from the bearing helps to fill the voids in the surfaces of the frictional interface, and thus maintains a smoothness in the surfaces and a desired friction-reducing efficiency of the bearing joint. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (a) a method for making a bearing; (b) a method for reducing wear in a bearing joint. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a bearing.
