Exception NSK Bearings say there are two versions, a bearings there is the use of bearing problem, the problem manifested bearings in general there is a difference.
Going to talk about today encounter problems in the process, NSK Bearings would happen then? Our how to operate it?
1 watt surface corrosion: spectra showed abnormal concentration of non-ferrous metal elements; iron spectrum submicron wear particles of many non-ferrous metal components; lubricants excessive moisture, acid value exceeded.
2 NSK bearing journal surface corrosion: spectra showed abnormal concentration of iron, iron spectrum the many iron components submicron particles, lubricants excessive moisture or acid value exceeded.
3 journal surface strain: Ferrography, cutting abrasive or black oxide particles of iron-based metal surface tempering color.
4 NSK bearings tile back fretting wear: spectra of the abnormal iron concentration, the many iron content in the sub-micron wear particles, lubricants moisture and acid value of abnormal iron spectrum.
5 NSK bearing surface strain: Ferrography, cutting abrasive, abrasive ingredients for non-ferrous metals.
