Additive load 'preload' improve deep groove ball bearing rigidity method

1, a single row deep groove ball bearing surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal. 2, single row deep groove ball 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. 3, bearing tile surface corrosion: spectrum analysis found that abnormal non-ferrous metal element concentration; Iron spectrum appeared a lot of non-ferrous metal components in sub-micron wear particles; Lubricating oil excess moisture, acid value exceeds bid. 4, bearing bush 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. In liquid lubrication condition, the 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 5, single row deep groove ball bearing journal surface strain: iron spectrum contains iron series cutting grinding grain or black oxide particles, metal surface heat tint.
