IKO miniature bearing failure of three internal causes

Miniature bearing failure - three internal reasons IKO bearing source melting technology center Shanghai bearing structural design, manufacturing process and material quality and so on three major factors in determining the quality of imported bearings. Miniature bearing structural design reasonable equipped with advanced at the same time, just can have a longer IKO bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. Metamorphic layer on the surface of a IKO bearings work in recent years research has shown that is close to the grinding process and the surface quality of bearing. The metallurgical quality of miniature bearing material was the main factors influencing the IKO bearing early failure. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still IKO bearing failure of one of the main influence factors. Select material adequacy is still bearing failure analysis factors must be considered. The main task of the miniature bearing failure analysis, which is based on a lot of background material, analyze data and failure forms, find out the main factors of IKO bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden.
