The main failure of sliding bearings:
      1, tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements abnormal; bearing bearing many non-ferrous metal components of the sub-micron wear particles; lubricating oil moisture, acid value exceeded.
      2. Corrosion of the journal surface: The spectral analysis revealed that the concentration of iron elements is abnormal. There are many sub-micron particles of iron in bearing bearings, and the lubricant has excessive moisture or acid value exceeding the standard.
      3, tile surface spalling: Bearings found in many large-scale fatigue exfoliation alloy wear particles, layered abrasive particles.
      4, tile back fretting wear: Spectral analysis found that the abnormal iron concentration, bearing many sub-micron iron particles wear particles, lubricants, water and acidity anomalies.
      5. The surface of the bearing is damaged: The cutting abrasive particles are found in the bearing, and the abrasive particles are non-ferrous metals.
      6, the journal surface of the pull: the bearing of iron cutting abrasive or black oxide particles, the surface of the metal there is a tempered color.
      7, bearing burning tile: Bearings have more large-size alloy abrasive particles and ferrous metal oxides.
