NSK bearings regularly check method, the bearing knowledge

NSK bearings for regular inspection, NSK bearings to maintain optimum condition is very important work, also can found the problem. NSK bearings on matters that should be paid attention in use and related knowledge. First of all, we have to stress is that it is important to keep NSK bearing lubrication and clean. So when we inspect the NSK bearings, NSK bearings should clean the surface, and then remove the perimeter of the bearing parts. Everyone should pay attention to, oil seal is very fragile parts, so in check and need to be careful, when disassembling do not excessive force, so as not to cause damage to parts. Then carefully check NSK bearing oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace, and bad seal will cause the damage of the bearing, NSK bearings make cloud caused by abnormal equipment downtime. Second, we will also examine the lubricant of NSK bearings. Lubrication is very important, not just for NSK bearings, also for all the import bearings. Note, however, FAG bearings is unfavorable and overmuch grease. NSK bearing lubricant on inspection method is: with little lubricant in friction between two fingers, and if the presence of pollutants, can be felt; Or in the back of a thin layer of lubricant, then seal of inspection. And then replace the NSK bearing lubricant. NSK bearings used engine oil lubrication after xie used engine oil, if possible, shall be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. Note: the oil before use it's best to filter it. NSK bearings with grease lubrication in replacing grease, Joe used in addition to the device should be avoided with cotton receive Angle to any part of the NSK bearings. Because these residues fiber may wedged in between the scroll and damage, especially the application of small bearing more need to pay attention to this problem. Finally, it is important to note covering exposed NSK bearings. Check the NSK bearings, don't let bearing exposure to pollutants or moisture environment. If the job is interrupted, 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 coating with brush with petroleum solvent ( whitespirit) Cleaning and dry with a lint-free cloth or with compressed air to blow dry, Be careful not to let the bearing component starting rotation) 。 With a little mirror, and the probe used in the similar to the dentist to check the bearing of the orbit plane, retainer and beads. If the bearing is not damaged, should be provided according to the original machine lubrication instructions or book of 204 pages to 247 pages of execution and lubrication. Do not clean the encrypted block or dust bearing; You just wipe the outer surface. If the bearing is need to replace damaged situation. During regular maintenance downtime time replacement bearings than the array bearing damage of selected into a sudden stop loss is much more economical.
