The main factors used to adjust is installed, use and maintenance, repair and other maintenance are in line with technical requirements. According to NSK Bearings installation, use, maintenance, maintenance of the technical requirements for running the NSK bearings bear the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection,abnormal immediately find out the reasons, adjustment, make it back to normal. Installation conditions are the primary factors used one of the factors bearing is often caused by improper installation package bearing between the various components of the stress state changes, bearing in abnormal state, and early termination of operation of the internal life of the main factors refers to the structural design, quality manufacturing processes and materials, three factors determine the quality of the bearing.

    Bearing materials, metallurgical quality of early bearing failure was the main influence factors. As metallurgical techniques (such as bearing steel vacuum degassing, etc.) progressing, to improve the quality of raw materials. Raw material quality factors in bearing failure analysis in the proportion has decreased significantly, but it is still bearing failure of one of the  main factors. The appropriateness of the selection is still bearing failure analysis must be considered.
