More careful investigation 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 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. Judge 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 damage and bearing abnormal situation, please according to the bearing damage phenomenon to find out the reason, to develop countermeasures. In addition, the test results, there are some defects, if the bearing can't use, need to replace new bearing. 一个。 Inner and outer ring, rolling body, to keep any of them are cracks and debris. b。 Inner and outer ring, rolling body any one strip. c。 Raceway surface, guard, significant injury of roller. d。 Maintains a badly worn or loose rivet badly. e.
