Sliding bearing of the main fault knowledge rules - bearing

1) Tile surface corrosion: spectrum analysis found that non-ferrous metal element concentration anomaly; Iron spectrum appeared a lot of non-ferrous metal components in sub-micron wear particles; Lubricating oil excess moisture, acid value exceeds bid. 2) Shaft neck surface corrosion: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum of submicron particles, water or high acid value oil paint. 3) Shaft neck surface strain: iron spectrum have iron series cutting grinding grain or black oxide particles, metal surface heat tint. 4) Tile back micro wear: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum wear submicron particles, lubricating oil moisture and acid value anomalies. 5) Bearing surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal.
