Integral sliding bearing considerations are as follows
1, the tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements anomalies; there are many non-ferrous metal sub-micron wear particles in the iron spectrum; lubricating oil moisture exceeded, acid value exceeded.
2, the surface of the journal corrosion: spectral analysis found that the concentration of iron is abnormal, there are many sub-micron iron particles in the iron spectrum, lubricating oil excessive or excessive acid value.
3, journal surface strain: iron spectrum in the iron-based abrasive particles or black oxide particles, the metal surface tempered color.
4, tile back fretting wear: spectral analysis found abnormal iron concentration, there are many ferrous iron sub-micron wear particles, lubricating oil moisture and acid value anomalies.
5, bearing surface strain: found in the iron spectrum cutting abrasive, abrasive composition of non-ferrous metals.
6, tile surface peeling: iron spectrum found in many large-size fatigue spalling alloy wear particles, layered abrasive particles.
7, bearing bushings: iron spectrum in the more large size alloy abrasive particles and black metal oxide. The above information by Hunan Jintai Hardware and Machinery Co., Ltd. finishing.
