To determine whether the removed bearings can be reused, after cleaning, we need to carefully check the raceway surface , rolling surface and the wear pattern of the bearing cage. If the bearing has the following defect , it can’t be used anymore.
1.Any of the out ring , inner ring , rolling element and cage have crack or notch.
2.There is obvious bruise or rust on raceway surface , bearing rib , or rolling element.
3.The bearing cage has observably abrasion or the rivet is flabby.
4.The surface of the inner diameter of cone and outer diameter of cup has obvious creep.
5.The obvious discoloration caused by the heat.
