Abstract: Many factors affect the integrity of precision ball bearings. In this study, the multi-dimensional controllability of precision ball bearings produced in different company brands (bearing A and bearing B) were studied and compared. The geometric errors (flatness, parallelism, roundness and cylindricity of inner and outer rings, roundness, groove and roughness of inner and outer rings) and vibration errors of bearings were analyzed. Concurrently, the residual stress, residual austenite content, element content ratio, metamorphic layer and temperature-vibration displacement coupling test were also analyzed. Based on the above analysis conclusion, the bearing fatigue life test was carried out for 2 150 h. The reliability of the conclusion is proved again as follows. When the residual austenite content in the raceway of precision ball bearing is 10%, the axial residual stress is 877.4 MPa; the tangential residual stress is 488.1 MPa; the carbon content is 6%; the test temperature of bearing is the lowest; and the service life is prolonged.
