We can see that the dn high value and there is a circle of stress, needle bearing the classification and various components, mark of the high speed steel paper surface treatment methods of low carbon content and high surface hardening the depth of the change is of great significance. Therefore, SKF developed material surface treatment, can strengthen the surface hardness, and produces stress. The surface treatment of the material has the following characteristics:  good psychological fatigue crack sex, the second stage, has the crack growth rate is low and the quenching is insufficient or low carbon content in the core fracture toughness of material value is higher.

SKF of surface treatment processing development of the methods include

(1) use shock, electron beam or induction quenching methods, such as the lack of ordinary high quenching local heat treatment, to get surface hardening layer. Water pump bearing here should be pointed out that quenching shortage is in order to improve the fracture toughness. just

(2) using chemical heat treatment method, the surface hardening layer. This method including the carbon or nitrogen through to the ordinary HSS microstructure, or small degree carbon content change.
In short, SKF company think for the next generation in aircraft engine for new steel analysis method or improve heat treatment process, FAG bearing can get the effect from the surface treatment of a significant benefits. Can say, if use heat treatment method of the development of microstructure and mechanical properties about once people have, quenching steel and high speed steel paper will through in aviation engine bearings for the full use.
