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.
