Summary: Check the condition of raceway surface, rolling surface and mating surface, as well as the wearing condition of the cage, etc. In addition, the degree of bearing damage, machine performance, importance, operating conditions, inspection period, etc., will be considered before determining whether the bearing can be used again or replaced. If bearing damage and abnormal conditions are found, find out the cause and develop countermeasures.
