NSK bearings with sliding NSK bearings operating under sliding conflicts. Sliding NSK bearings work smoothly, securely and without noise. Under smooth liquid conditions; the sliding surface is separated by smooth oil without direct touch; it can also greatly reduce conflict losses and appearance. Wear; oil film also has a certain vibration absorption ability. The use of sliding NSK bearings; the use is also very extensive; how do we deal with the problems of sliding NSK bearings? Is there a better way? Let me explain to you the common sense of association below; I hope to assist you.
Common problems with sliding NSK bearings are as follows:
1, tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements is abnormal, the iron spectrum presents a number of non-ferrous metal components of sub-micron wear particles, smooth oil moisture overrun, acid value overrun.
2, NSK imported bearing shaft neck external strain: iron spectrum cutting iron particles in the iron spectrum; metal appearance tempering color.
3, NSK bearing journal corrosion: spectral analysis found that the concentration of iron is abnormal; the iron spectrum has many iron submicron particles; smooth oil moisture overrun or acid value overrun.
4, NSK bearing external strain: found in the iron spectrum cutting abrasive; abrasive particles are non-ferrous metals.
5, fretting wear behind the tile: spectral analysis found that the iron concentration is abnormal; there are many iron components in the iron spectrum sub-micron wear particles; smooth oil moisture and acid value is abnormal.
