The process requirements of long-life bearing can provide the bearing manufacturer with process quality requirements that are beneficial to the extended bearing life when necessary; for example, the stress condition of the tumbling appearance and the handling requirements of the processing enthalpy layer. Generally speaking; the tumbling appearance is at Moderate compressive stress is better; however, it is also necessary to contact the external stress change rate from grinding to superfinishing; to determine the process parameters that are most conducive to bearing fatigue life; in this respect; Cooperation can be solved.
The tumbling layer of the tumbling surface mainly refers to the oxide layer, the work hardening layer and the arrangement of the distortion layer, which have physical and chemical properties with the outer metal layer of the base metal; their own strength is often poor and the matrix is ​​not firmly connected; the bearing is hurt Labor life and wear life are extremely arrogant; should be controlled.
