NSK bearings in sliding friction work under the NSK bearings. NSK bearing stable, reliable, without noise. In liquid lubrication condition, sliding surface is oil and not direct contact with separate happened, also can greatly reduce friction loss and surface to wear, the oil film still has certain ability and vibration. NSK bearing, the application of use is very extensive, for we meet NSK bearing of the appearance of the sliding fault we how to solve? What better way? Next, let I to give you knowledge of relevant interpretation, the hope can help you.

NSK bearing common faults are as follows:

1, tile surface corrosion: spectrum analysis found that non-ferrous metal elements abnormal concentration; Iron spectrum in appeared many non-ferrous metal components of sub-micron wear particle; Oil water overweight, acid value exceeds bid.

2, NSK bearing shaft neck a surface import: iron spectrum in the iron series cutting grits or black oxide particles, the metal surface HuoSe back there.

3 NSK bearing shaft neck, surface corrosion: spectrum analysis found that iron concentration is unusual, many of iron spectral composition of submicron particles of iron, lubricating oil moisture exceeds bid or acid value exceeds bid.

4, NSK bearing surface strain: iron spectral cutting grits are found, grits for the nonferrous metal components.
5, watts back fretting wear: spectrum analysis found that iron concentration is unusual, iron spectral many iron composition sub-micron wear particle, lubricating oil water and acid value abnormalities.
