Some customers complained that the life of many high-speed spindle bearings was too short, resulting in a waste of costs. In fact, many bearings were originally unnecessary to be replaced to avoid unnecessary waste. So what are the reasons for the high-speed spindle bearings to be replaced? There are probably two reasons: The first is the lack of tight sealing, and the quality of the bearing itself has certain problems; the second is the problem of grease, the bearing clearance is large, the reason is that the grease in the bearing is less, and the grease may not be enough at the beginning, or After the test of high temperature and high speed, the bearing oil inside will directly become liquid and drip off. Therefore, in addition to the quality problem in domestic bearing manufacturing, the selection of lubricating oil for bearings is also very important, which is often overlooked by customers, especially for high-speed spindle bearings, due to their relatively high-speed operating environment and high temperature It is easy to cause grease loss, resulting in bearing damage, so it is necessary to equip with good bearing grease. 37 years of professional manufacture of high-speed spindle bearings, tailor-made solutions!
