In order to determine whether the self aligning ball bearing can be reused, the dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and seal ring should be examined.
Because the bearing can not rotate by hand, pay attention to the inspection of the rolling body, raceway surface, cage, retaining surface and other appearance, the more important the bearing, the more careful inspection must be.
With regard to the inspection results, it can be judged by the use of inertial bearings or proficient bearings.
Judgment criteria vary according to mechanical performance, importance, and inspection cycle. If the damage is below, the bearing shall not be reused and must be replaced.
(1) fracture and defect of self aligning ball bearing parts.
(2) stripping of rolling surface of raceway surface.
