When the equipment is regularly overrepaired, the operation is inspected and the peripheral parts are replaced, it is necessary to carefully inspect and record the appearance of the self-lubricating bearings to determine whether the self-lubricating bearings that have been removed can be used again. In order to find and investigate the remaining lubrication dose, the self-lubricating bearing must be thoroughly cleaned after sampling. Check the condition of the raceway surface, rolling surface and mating surface, as well as the wear state of the cage, for any damage or abnormality. After considering the degree of damage of self-lubricating bearings, machine performance, importance, working conditions, inspection cycle, etc., self-lubricating bearings can be used or replaced again. If the self-lubricating bearing is damaged or abnormal, please find out the reason and make countermeasures. If the following defects exist, self-lubricating bearings can no longer be used, and a new self-lubricating bearing needs to be replaced. The following is a small edition of Hangzhou self-lubricating bearings to explain it, I hope to be helpful to you.

Hangzhou self-lubricating bearings

1. Cracks and debris exist in the inner ring, outer ring, rolling body and cage.

2. The inner and outer rings and either of the rolling elements have fallen off.

3. Raceway surface, ribs and rolling elements are severely stuck.

4. Cage is seriously worn or rivet is seriously loose.

5. Raceway surface and rolling element are rusted and scratched.

6. There are obvious dents and marks on the rolling surface and rolling elements.

7, the inner diameter surface of the inner ring or the outer diameter of the outer ring has creep.

8. Serious discoloration due to overheating.

9. Sealing ring and dust cover of grease seal self-lubricating bearing are seriously damaged.

The above nine points are all the contents of the nine points to judge whether self-lubricating bearings can be used again. Thank you for your understanding and support!
