Regular inspection of the bearing seal is to maintain the bearing in the best condition is very important work. The most advantageous inspection time is arranged in regular outage inspection period. The importance of clean bearing: it is important to keep the bearing and lubrication clean. Need before checking surface cleaning machine, and then remove the perimeter of the bearing parts. Oil seal is very fragile parts, so need to carefully remove, not excessive force, and then carefully check oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace the bad oil seal will cause the damage of the bearing and the cause of equipment downtime. Check the lubricant of lubricant on friction between two fingers, if the presence of pollutants, can feel out, or in the back with a thin layer of lubricant, then seal of inspection. Replace the lubricant oil lubrication bearing after xie used engine oil, possible, 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, then spilled oil in addition to these, the oil before use it's best to filter it. Grease lubricated bearings should avoid when replacing grease with cotton material come into contact with any part of the bearing, 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. Covering exposed bearing inspection bearing, don't let bearing exposure to pollutants or moisture environment. If the job is interrupted, should with oil or similar materials cover paper plastic film 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 according to the lubrication instructions provided by the machine manufacturer's proposal execution of 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.
