Imported bearings regular maintenance precautions

Imported bearing equipment, regular maintenance, operation and replacement of external parts to be removed when the imported bearings for inspection, you need to determine in turn the secondary bearing parts can be re-used and record the use of better than bad. Also need to carefully investigate and record the demolition of imported bearings and appearance. In order to clarify and investigate the remaining amount of lubricant, after sampling, to clean the bearings a second time to check the imported bearing raceway surface, the rolling surface and the mating surface of the state and the cage wear and tear with or without damage and abnormal In particular, the situation should be observed raceway running track. Determine the bearing can be reused, to consider the extent of bearing damage, machine performance, importance, operating conditions, check the cycle after the decision. Check the results, if the import bearings are found to be damaged and abnormal circumstances, please identify the cause of the bearing damage, develop measures. In addition, the inspection results, if there are several defects below, imported bearings can not be reused, you need to replace the new bearing. a. Inside and outside the ring, rolling body, cage any one of the cracks and debris. b. Inside and outside the ring, rolling any one of them peeled. c. raceways, ribs, rolling body significant card injury. d. cage wear or serious rivets wear powerful. e. raceway surface, rolling body rusty and scars. f. rolling surface, there are significant rolling indentation and marking. g. Inner diameter or outer surface of the outer diameter of the creep. h. overheating discoloration amazing. i. grease seal bearing seals and dust cover to a serious damage.
