Factors lead to bearing life is short

Bearing can usually install space is limited. In most cases, the axis ( Or bearing inside diameter) According to mechanical design or other design limitations. Bearing type and size, so choose the decision of the bearing is based on the diameter. Therefore, the main dimensions of the bearing table standards are in accordance with the international standard diameter. There could be many factors that affect the bearing life, from the use of further explanation of the factors and internal factors. Install and use the adjustment factor, use and maintenance, maintenance and other technical requirements, accord with. According to the bearing installation, use, maintenance, maintenance of bearing the technical requirements of the operation, in contact with the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. Installation condition is one of the factors of using bearing is often caused by incorrect installation package of the parts between the change of state of the primary factors of bearing capacity in the abnormal operation status, and living the early termination of the internal factors mainly refers to the structure design, the quality of the manufacturing process and materials, there are three factors determine the quality of the bearing. Is the main factor influencing the quality of bearing material metallurgy rolling bearing early failure. With the progress of metallurgical technology ( Such as bearing steel, vacuum degassing, etc. ) , the quality of raw materials to improve. The proportion of raw materials quality factors in the analysis of the bearing significant decline, but it is still one of the main factors of bearing failure. Choose proper is still bearing failure analysis must be considered. Bearings are generally through forging, heat treatment, cutting, grinding and assembly process operation. Processing technology, advanced and reasonable will influence the stability of the bearing life. Affecting the bearing product of heat treatment and grinding process, often with the bearing fault is more directly related to the quality of the product. In recent years, the deterioration of the surface layer of the bearing show that the grinding process is closely related to the bearing surface quality. Bearing life analysis based on a lot of background material, is the main task of the data and failure mode analysis, find out the main factors of bearing failure, in order to make targeted improvements, prolong bearing's service period, in order to avoid breaking the onset of early failure of the bearing.
