When judging whether the disassembled bearing can be used again, check the tapered roller bearing aftercleaning, carefully check the state of the raceway surface, rolling surface, and mating surface,the wear of the cage, whether the bearing clearance increases, and whether there is damage or abnormality that affects the decrease of dimensional accuracy. Non-separable small ball bearings, etc.,
Use one hand to flat-end the inner ring and rotate the outer ring to confirm that it is smooth.
Separate bearings, such as tapered roller bearings, can separately inspect the rolling elements and raceway surfaces of the outer ring.
Because large bearings cannot be rotated by hand, pay attention to check the appearance of rolling elements, raceway surfaces, cages, rib surfaces, etc. The higher importance of the bearing, the more careful checking.
When judging whether the bearing can be used again, it should be based on related factors such as bearing damage, mechanical performance, importance, operating conditions, inspection cycle, etc. However, if the following defects are found during the inspection, the bearing cannot be used continuously and a new bearing needs to be replaced.
