How to judge whether marine bearings are damaged?

Whether the marine bearing can be used again depends on the degree of damage, mechanical properties, importance and working conditions of the bearing

However, if the following defects are found during the inspection, the bearing can no longer be used, so it needs to be replaced.

One kind. There are cracks or gaps in the inner ring, outer ring, rolling element and cage.

B. Either of the ferrule or the rolling element is broken.

C. There are obvious scratches on the rolling surface, ribs and rolling elements.

d. Or the rivet is obviously loose. Stick to frame and wear clearly.

e. Rust or scratch on raceway surface and rolling element.

F. There are serious dents or bumps on the raceway surface and rolling elements.

g. There is obvious creep on the inner diameter surface of inner ring or outer diameter surface of outer ring.

h. Discoloration is evident due to overheating.

Overall maintenance of bearings?

Comprehensive maintenance of bearings includes cleaning, disassembly, inspection, roller grinding or replacement of inner and outer rings, manufacturing of new rolling elements / grinding of original rolling elements, replacement of rolling elements, assembly, clearance adjustment and inspection of damaged packages of bearings.

Comprehensive and strict maintenance process to ensure that the repaired bearing meets the performance requirements of the new bearing.
