Bearing inspection and judgment
2022-08-26
In order to judge whether the removed bearing can be reused, it is necessary to focus on checking its dimensional accuracy, rotation accuracy, internal clearance, and mating surface, raceway surface, cage and sealing ring.
Since large bearings cannot be rotated by hand, pay attention to checking the appearance of rolling elements, raceway surfaces, cages, rib surfaces, etc. The higher the importance of the bearing, the more careful inspection is required.
Regarding the inspection results, the judgment can be made by those who use inertia bearings or are proficient in bearings.
Judgment criteria vary according to mechanical properties and importance, inspection cycle, etc. In case of the following damage, the bearing shall not be reused and must be replaced.
1) Fractures and defects of bearing components.
2) Peeling of the rolling surface of the raceway surface.
