In order to determine whether the removal bearings can be used as before.we often check the bearing after clean. we should check the groove surface, the raceway, and seating’s condition, wear pattan of retainer, and the inceasing of bearing clearance and about dimensional accuracy has nothing to do down the damage. For the Non-separation-type small ball bearings,we often support the the inner ring to level with one hand , and make the rotating the outer ring to confirm smooth.
The Tapered roller bearings and other separation-shaped bearings,we can check each one about rolling body and the outer ring raceway
Because of the Large bearings we can not rotate by hand, be careful to check rolling, raceway surface, retainer, raised edge face and other exterior surfaces, The more importance the bearing have the more cautious we should when we examine it.
