Bearing failure forth the most prone

Presentation slide bearings at work because the contact pad journal and conflicts occur, resulting in the appearance of heat, wear, even "killed", so when planning the bearing, should be used with good anti-friction bearing bush materials production, the selection of a suitable and the adoption of appropriate lubricant supply ways to improve the bearing structure in order to obtain a thick film lubrication.
1, tile surface corrosion: spectral analysis found abnormal concentrations of non-ferrous metal elements; iron spectrum presented submicron wear particles of many non-ferrous metals; lubricating water overruns, Koh overruns.
2, the outer corrosion journal: spectral analysis found abnormal concentrations of iron, iron spectrum, there are a number of sub-micron particles of iron component, moisture overruns or lubricating oil acid value overruns.
3, the appearance of the journal strain: iron spectrum in the presence of an iron-based cutting temper color or black oxide abrasive particles, metal appearance.
4, tile back fretting: spectral analysis found abnormal concentrations of iron, iron spectrum, there are many iron content submicron wear particles, water and an acid number of abnormal lubricants.
5, the outer bearing strain: iron spectrum found in cutting abrasive, abrasive composition of non-ferrous metals.
6, tile off: iron spectrum found in many large-scale fatigue shedding alloy wear particles, layered abrasive grains.
7, the bearing bush-burning: iron spectrum, there are more large-scale abrasive alloy and black metal oxides.
