Preventive maintenance methods of KOYO thrust ball bearing premature failure

Check before cleaning machine appearance first, then remove the KOYO bearing the perimeter of the parts. Oil seal is very fragile parts in need to beware of disassembly, not excessive force, and then carefully check the oil seal and its surrounding parts, if already presents the adverse conditions, be sure to switch off, and bad seal will incur import bearing damage and severe equipment downtime. Check the smooth agent, smooth agent with a little friction between two fingers, if the presence of pollutants, can find out, or in the back with a thin layer of smooth agent, then seal of inspection. Smooth change agent, the oil slick KOYO bearings after xie used engine oil, oil impregnated with novel and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, then spilled oil in addition to these, the oil it's best to filter it before use. A, improper device ( Accounts for about 16%) 1, the device using a brute force, directly with a hammer percussion bearing of KOYO bearing damage; Is the main reason of the deformation. 2, the device does not reach the designated position, device is biased or not installed in the thrust ball bearing, bearing clearance is too small. Inside and outside the circle is not in the same rotation center, forming different heart. Initiative: choose the right or a professional bearing assembly tools, devices with a special instrument to detect the end of. Second, the smooth bad ( Accounts for about 50%) According to the survey, smooth bad is one of the main reason for forming KOYO bearing premature failure. Main reasons including: failure to smooth filling agent or smooth oil; Smooth agent or smooth oil not filling in place; Smooth agent or smooth oil improper selection; Smooth way is not correct, and so on. Initiative: choose the right smooth agent or smooth oil, use the right way to smooth filling. Third, pollution, Accounts for about 14%) Pollution can also cause premature thrust ball bearing damage, pollution is refers to the dust, metal scraps into KOYO bearings inside. Main reasons including: apply early to open the bearing before packing, formation pollution; Device when the working environment is not clean, formation pollution; Bearing of the working environment is not clean, working medium pollution, etc. Initiative: before use it is best not to unpack the KOYO bearings; Device when the device environment clean, bearing on the use of the to stop cleaning; Strengthen the thrust ball bearing seal installation. Four, tired, Accounts for about 34%) Fatigue damage is a common way of damaged bearing. Common fatigue damage reason may be: KOYO bearing long-term overload operation; Not timely maintenance; Improper maintenance; Equipment bearing exposure to pollutants or moisture environment. If work infix, should with oil film, paper or similar material by machine. If don't have to remove and may perform inspection of cleaning without masking of bearing, to clean with brush with petroleum solvent coating, then dry with a lint-free cloth or use a tightening air blow dry, Pay attention to don't let the thrust ball bearing component starting rotation) 。
