Self-lubricating bearings the main fault note

Since smooth bearings in the job because the journal and bearing touch a conflict occurs, resulting in the appearance of heat, wear, even “killed” and other problems, so when depicted bearing, should be used with good anti-friction bearing bush materials production, appropriate Glazes and choose the appropriate supply of ways to improve the layout in order to obtain a thick film bearing smooth and so on.
1, tile surface corrosion: spectral analysis found abnormal concentrations of non-ferrous metal element; bearing presents submicron wear particles of many non-ferrous metal components; lubricating oil moisture overruns, Koh overruns.
2, the outer corrosion journal: spectral analysis found abnormal concentrations of iron, bearing in many submicron particles of iron component, moisture overruns or lubricating oil acid value overruns.
3, tile shedding: bearings were found to have many large-scale fatigue shedding alloy wear particles, layered abrasive grains.
4, tile back fretting: spectral analysis found abnormal concentrations of iron, iron-bearing components in many sub-micron wear particles, water and an acid number of abnormal smooth oil.
5, since the smooth outer bearing strain: bearings were found to have cutting abrasive, abrasive component of non-ferrous metals.
6, the composite outer strain journal: Bearing in the presence of an iron-based cutting temper color or black oxide abrasive particles, metal appearance.
7, the bearing bush-burning: bearing alloy grains have more large-scale black and metal oxides.
