JINTAI Sleeve Bearing Manufacturer is gradually transferred to the hard lubricating film formed by the abrasive wear self-lubricating material in the initial stage of the work. The friction and wear properties mainly rely on the performance of the solid lubricant. Self-lubricating bearing face material is usually made of copper alloy, aluminum alloy - bimetallic, babbitt, etc., PTFE, modified polyoxymethylene, rubber, molybdenum disulfide, black lead and so on. Its solid self-lubricating bearing surface can form a solid lubricating film after the movement of the sub-surface separation, sliding friction can be greatly reduced, but also to avoid the shaft wear.
Solid lubricating film for the solid self-lubricating bearing face material itself has a good self-lubricating properties, in the initial stage of the work gradually through the wear and tear self-lubricating material gradually transferred to the surface of the grinding parts of the surface of the formation of hard lubricants; This is a certain requirement for the roughness of the face of the workpiece, generally in the order of Ra0.4 ~ 1.6; too bright or too rough surface is not conducive to the transfer of lubricant to the work surface hindered the completion of the lubricating film; Solid lubricating bearings are generally required to be grinding surface to the polished surface; when the solid lubricating film is fully formed, the movement between the shaft and the bearing has actually turned into a friction between the lubricating film and the bearing movement, the shaft is not directly Contact with the bearing surface.
