There are 4 groups of car wheel bearings, in which the inner ring of the 2 groups of bearings were reinforced by grinding process while the other 2 groups of bearings were not. After finishing grinding, then following by superfinishing to make them fit with steel and cage. When it was completed, 4 groups of bearings on the bearing fatigue testing machine were able to test the change of surface quality, operation temperature, vibration and clearance. The result shows that the surface quality, operating temperature, vibration and clearance changes of bearings are better than those untreated after reinforced grinding.
