Judging whether the bearing can be used again depends on the damage level of the bearing, mechanical properties, importance, operating conditions, inspection cycle and other related factors.
However, if the following defects are found during the inspection, the bearing cannot be used any more and the new bearing needs to be replaced.
1. There is a crack or a gap in any one of the inner ring, the outer ring, the rolling element, and the holding frame.
2. Any one of the ferrule and the rolling element has a break.
3. There are obvious scratches on the rolling surface, the ribs and the rolling elements.
4. Or the rivet is obviously loose. Stick to the frame and wear it clearly.
5. There are rust or scars on the raceway surface and rolling elements.
6. There are serious indentations or bumps on the raceway surface and rolling elements.
7. There is obvious creep on the inner diameter surface of the inner ring or the outer diameter surface of the outer ring.
