The analysis for the reason of NSK bearings failure

       NSK-aligning ball bearing failure is often due to multiple factors, the impact of all design and manufacturing process factors and the failure of the bearing analysis it is not easy to determine. Under normal circumstances, in general you can use factors and internal factors from both the consideration and analysis. Is installed using the adjustment factors, use and maintenance, maintenance repair and other technical requirements for compliance. Installation conditions are the primary factors used one of the factors bearing is often caused by improper installation package of the bearing force between the various parts the state changes,  NSK bearing in an abnormal state of operation and early failure. According to the bearing installation, use, maintenance, maintenance of the technical requirements for operation of the bearings are exposed to load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find out the reasons, to adjust to back to normal. In addition, the quality of the grease and the surrounding medium, the atmosphere is also very important for analytical testing.
        Internal factors mainly refers to the structural design, quality manufacturing processes and materials, three factors determine the quality of the bearing.
First, the structure design has advanced with the same time, will have a longer bearing life. Bearings are generally made through forging, heat treatment, turning, grinding and assembly of multi-channel processing operations. The reasonableness of the processing technology, advanced, will also affect the stability of the bearing life. Which affect the quality of the finished product bearing the heat treatment and grinding processes, often associated with the failure of the bearing has a more direct relationship. In recent years, deterioration of the bearing surface layer of studies have shown that the grinding process is closely related with the quality of the bearing surface. 
    NSK-aligning Self-aligning ball bearing NSK metallurgical quality of the material impact of rolling early failure was a major factor. With metallurgical technologies (such as bearing steel, vacuum degassing, etc.) of progress, raw material quality is improved. Raw material quality factors in the bearing failure analysis in the proportion has decreased significantly, but it is still bearing failure is one of the main factors. The appropriateness of the selection is still bearing failure analysis must be considered. 
       NSK-aligning ball bearing failure analysis of the main task, is based on a lot of background material, analysis of data and failure mode, identify the main factors causing bearing failure, in order to make targeted improvements to extend bearing service period, to avoid bearing sudden occurrence of early failure.
