The main fault of sliding bearings: 1, tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements anomalies; bearing a lot of non-ferrous metal sub-micron wear particles; lubricating oil moisture exceeded, acid value exceeded. 2, the surface corrosion of the shaft: Spectrum analysis found that iron concentration is abnormal, there are many iron bearing sub-micron particles in the bearing, lubricating oil excessive or excessive acid value. 3, tile surface peeling: Bearing found in many large size of the fatigue spalling alloy wear particles, layered abrasive particles. 4, tile back fretting wear: Spectrum analysis found abnormal iron concentration, there are many iron bearing sub-micron wear particles, lubricating oil moisture and acid value anomalies. 5, bearing surface strain: bearing found in cutting abrasive, abrasive composition of non-ferrous metals. 6, journal surface strain: bearing iron cutting abrasive particles or black oxide particles, metal surface tempered color. 7, Bearing bushings: bearing more large size alloy abrasive particles and black metal oxide.
