First, the structure of a reasonable design at the same time with advanced, there will be a longer life of imported bearings. Bearing manufacturing generally after forging, heat treatment, turning, grinding and assembly and other processing procedures. The rationality of the processing technology, advanced, stability will also affect the life of the bearing. Which affects the quality of finished imported bearings heat treatment and grinding processing procedures, often with the failure of imported bearings have a more direct relationship. In recent years, the import bearing working surface deterioration layer of the study shows that the grinding process and import bearing surface quality of the close relationship.

Secondly, the metallurgical quality of imported bearing materials used to be the main factor affecting the early failure of rolling bearings. With the progress of metallurgical technology (such as bearing steel vacuum degassing, etc.), the quality of raw materials has been improved. Raw material quality factors in the failure analysis of imported bearings accounted for the proportion has been significantly reduced, imported bearings, but it is still bearing failure of one of the main factors affecting.
Third, the selection of material is still appropriate import bearing failure analysis must be considered. Import bearing failure analysis of the main task, is based on a large number of background materials, analytical data and failure form, to find out the main factors causing the failure of imported bearings, in order to targeted improvement measures to extend the service life of SKF imported bearings, to avoid sudden early failure of the bearing. Installation conditions is one of the primary factors in the use of factors, import bearings often due to the installation of inappropriate and lead to a complete set of import bearings between the various parts of the force state changes, import bearings in the abnormal state of operation and early failure. According to the import bearing installation, use, maintenance, maintenance of the technical requirements of the running bearing load, speed, operating temperature, vibration, noise and lubrication conditions for monitoring and inspection, found abnormal immediately find the cause of the adjustment, so that it back to normal.
