Sliding NSK bearing NSK bearings under the sliding friction work.
NSK bearing sliding work steady, reliable, no noise.
Under the condition of fluid lubrication, sliding surface is lubricating oil without direct contact, also can greatly reduce the friction loss and wear of surface oil film also has a certain vibration absorbing ability.
The use of sliding NSK bearings, is also very versatile, for we meet with the emergence of NSK bearing sliding failure we how to solve?
What is the better way?
To explain to you the following related knowledge, hope to help you.
NSK bearing sliding common faults as follows: 1, the 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.
NSK import bearing journal surface strain: 2, iron series of ferrographic cutting grinding grain or black oxide particles, metal surface heat tint.
3, NSK bearing journal 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.
4, NSK bearing surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal.
5, 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.
