Sliding bearing bearing manufacturer what causes wear?

Sliding bearing bearing manufacturer what causes wear? Bearing manufacturer about sliding bearing wear what causes? Arising in the course of sliding bearing work wear form basically has the following kinds: 1, normal wear bearings used in the right conditions of wear and tear; Work at this time of bearing wear mainly for the initial stage of bearing lubrication material to the transfer of the grinding shaft surface results, when establishing the ideal lubrication bearing wear rate is gradually reduced after vice. 2, crawling wear caused by axial surface roughness too smooth friction surface creep; Shaft surface is too smooth, sliding bearing the lubrication material can't transfer into the pits of shaft surface formed in the lubricating film, makes the ideal of the friction pair cannot be established; At this point bearing friction coefficient increases, the required driving force also will increase; 3, ploughing wear caused by the shaft is too rough phenomenon in the furrows of the friction surface scratch; Shaft surface height difference is too big, from the transfer to the surface of the bearing lubrication material not the formation of strong ideal smooth friction surface; At this time of wear essence is scratch wear; 4, adhesion wear caused by beyond the safe operation of the bearing temperature or optical axis agglutination; Optical axis in the bearing operating temperature exceeds the allowed temperature to the safe operation of the adsorption on the surface of the bearing friction that has taken place partly softening and formation of the wear and tear. 5, burns the wear caused by the friction surface of burn wear running too fast; Bearing shaft run faster than allowed by the running speed can cause friction surface due to friction into frictional heat rising sharply, a sharp rise in the friction heat on the friction surface of burn quickly.
