IKO thrust angular contact ball bearing inspection repair to the attention of the problem

Of IKO bearing equipment preventive maintenance, and peripheral parts replacement operation were thrust angular contact ball bearing is removed for inspection, to determine whether IKO bearing parts in turn can be used again and record the usage of good from bad. Carefully investigate and record the bearing and the appearance of being removed. In order to explore the residual amount of investigation and lubricant, after sampling, to clean the bearing well. Second check IKO bearing raceway surface, rolling surface and cooperate with the surface condition and wear conditions of cage with and without damage to watch the race and abnormal situation especially the running track. To determine thrust angular contact ball bearing can use again, to the extent of the damage in considering bearing, machine performance, importance, and operation conditions, such as inspection period to decide later. Test results, if found IKO bearing damage and abnormal situation, please according to the bearing damage phenomenon to find out the reason, formulate countermeasures. In addition, the test results, there are some defects, if thrust angular contact ball bearings can no longer use, the need to replace new bearing. 一个。 Maintains a badly worn or loose rivet badly. b。 Raceway surface, rust and roller has a scar. c。 Had a remarkable indentation rolling surface, rolling body and make a mark. d。 Inner ring diameter or outer diameter on the creep. e. Discoloration of overheating. f。 Grease seal IKO bearing seal ring and dust cover damage to serious. g。 Inner and outer ring, rolling body, to keep any of them are cracks and debris. h。 Inner and outer ring, rolling body any one strip. 我。 Raceway surface, guard, significant injury of roller.
