In order to distinguish apart down deep groove ball bearings are not able to re-use, to the deep groove ball bearing rear view wash clean, carefully view the raceway surface, rolling surface, the surface condition of cooperation, maintaining shelf wear condition, deep groove ball bearing clearance and whether to add precision to reduce damage on the scale, unusual. Non-parting Small ball deep groove ball bearings, the inner ring with one hand support level, recognition is not rotating outer ring circulation.
Deep groove ball bearings and other parting shaped groove ball bearings, capable of rolling body raceway outer parting view.
Large deep groove ball bearings because they can not rotate by hand, pay attention to see rolling body raceways and cage, and other exterior wall surface, the higher the importance of deep groove ball bearings to be the more prudent view.
Is not available then the use of judgment, is the extent of damage to ponder deep groove ball bearings, mechanical properties, the importance of working conditions, the time until the next maintenance and resolutions. However, if the following disadvantages can no longer use, it is necessary to replace the new deep groove ball bearings:
(A) an inner ring, an outer ring, rolling body, keeping any cracks or notches on a shelf;
(B) rings, cracking any body roll on;
(C) raceway, a significant injury on card wall, roll body;
(D) the holder wear significantly, perhaps dramatically loose rivets;
(E) raceway, rolling rust on the body, injury;
