    The solid lubricating film is a solid self-lubricating bearing,Wrapped composite dry sliding bearing working surface material which has good self-lubricating property, and gradually moves to a hard lubricating film formed by the wear-and-wear self-lubricating material in the initial stage of work to the pit on the working surface of the grinding piece; This has certain requirements on the roughness of the working surface of the grinding part, generally required to be between Ra 0.4 and 1.6; too smooth or too rough surface is not conducive to the transfer of lubricant to the working surface, hindering the construction of the lubricating film; For solid-lubricated bearings,FU iron bushing-powder sintered the general requirement is to grind the surface to the polished surface; when the solid lubricating film is completely formed, the movement between the shaft and the bearing has actually been transformed into the frictional movement between the lubricating film and DU oilless dry bushing, and the shaft is actually not directly In contact with the bearing surface.
