Common faults of sliding bearings?

Main failure of sliding bearing:
1, tile surface corrosion: spectral analysis found that non-ferrous metal element concentration anomalies; bearing in the emergence of many non-ferrous metal components of sub-micron wear particles; lubricants moisture exceeded, acid value exceeded.
2, journal surface corrosion: spectral analysis found that iron concentration anomalies, bearing bearings in many iron components of submicron particles, lubricating oil moisture or acid value exceeded. 3, tile surface peeling: bearing found in many large-size fatigue flaking alloy wear particles, layered abrasive.
4, tile back fretting wear: spectral analysis found that iron concentration anomalies, the bearing has many iron components submicron wear particles, lubricating oil moisture and acid value anomalies.
5, bearing surface strain: bearing found in the cutting abrasive, abrasive composition of non-ferrous metals.
6, journal surface tension: bearing iron cutting grain or black oxide particles, the presence of metal surface tempering color.
7, bearing burner: the bearing has more large size alloy abrasive and ferrous metal oxide.
