Introduction: the roughness smaller rolling appearance requirements for high-precision bearings for the technology means inappropriate, this smooth surface is not formed by the cutting, but the abrasive squeeze rub role, the appearance will transformation layer formed by plastic flow, china bearing supplier in fact, the bearing life is also very unfavorable, should be controlled.

For example, on the rolling surface of the stress state and the processing deterioration layer control requirements. Generally speaking, the user may be necessary to the bearing factory will help extend bearing life and process quality requirements. Rolling appearance in a moderate compressive stress,bearing factory but also combined with the stress rate of change of surface grinding to superfinishing, competence to determine the most conducive to the process parameters of the bearing fatigue life in this area should be made bearing the relevant professionals with the talent to be addressed.

Own stre ngth is often very poor with the substrate is not strong, rolling appearance of the transformation layer mainly refers to the oxide layer, the hardening layer and the organization of distortion layer on the physical and chemical properties of the outer surface of base metal. The pain of the bearing fatigue life and wear life are extremely unfavorable, should be uncontrolled.bearing factory in china
