Corresponding measures to improve the installation method (used and charging, using appropriate tools folder). Correct loading conditions. INA bearings installed, sidewall support.
First of all, reasonable structure design of both have advanced, there will only be a longer thrust ball bearing life. Manufacture of bearings are generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced processing technology, will also affect the stability of the bearing life. Which affected the quality of finished product bearing heat treatment and machining processes, often has a more direct relationship with INA bearing failure. On bearing surface modification layer of work in recent years studies have shown that close to grinding and surface quality of bearing.
Thrust ball bearing metallurgical quality of the materials used to be the main factors affecting the early failure of rolling bearings. As metallurgical technology (such as bearings, such as vacuum degassing of steel) of the progress, raw materials quality has been improved. Raw materials quality factors of INA bearing failure analysis of market share has declined significantly, but it is still one of the main factors bearing failure. Selection of propriety are still bearing failure analysis of factors that must be taken into account.
Main tasks of bearing failure analysis, is based on the large amount of background material, analysis of data and failure mode, identify major factors contributing to thrust ball bearing failure, so targeted for improvement measures, extending the service period of bearing, avoid unexpected early INA bearing failure.
Secondly might be too much load (preload is too large). Excessive speed. Clearance is too small. Water or other foreign bodies penetrated. If the above two conditions are not so is the poor accuracy of axle and bearing boxes, large deflections of the shafts. See here, I think we all want to know the way of solving the problem, first of all, to research on lubricant and lubrication method, selected the INA bearing lubricant, and its usage, but also to correct the thrust force ball bearing's choice. Research in line with, bearing clearance and preload, and improved sealing device. Check the accuracy of the shaft and housing.
