Through a lot of rolling bearing failure analysis research shows that, at the loss of bearing or an early precision, have a plenty of the materials manufacturing defects or improper, but to a great extent because they were not strictly according to the bearing is used for installation, maintenance, or improper selection is bearing or actual load than bearing itself causes such as the rated load bearing abnormal damage.

For example, bearing parts of spalling fatigue in the very great degree is for lubricating oil mixed with impurity cause. Visible, to realize the rolling bearing has a longer and precision keep period, in addition to request bearing manufacturer to improve product quality outside, bearing the user will also have to use the method of science and programs use bearing, otherwise, again good bearing also in the rough casual use conditions die young.

 
The rolling bearing is a kind of precision mechanical support element, bearing the user deeply hope into host bearing can use period to avoid damage and keep its dynamic performance, but the objective facts sometimes is not satisfactory, sudden bearing failure accident will give users caused heavy loss.
