 Ring and rolling element materials:
Rings and rolling usually use high carbon chromium bearing steel. Most of the bearings, the use of SUJ2 JIS steel. Large bearing SUJ3.
The SUJ2 the chemical composition , in the world, as bearing materials have been normalized. For example: AISL52100 (USA), DIN100Cr6 (West Germany), BS535A99 (UK), etc. are the same kinds of steel.
Further need for impact-resistant case, use as a bearing material chrome steel, chrome molybdenum steel, nickel chromium molybdenum steel, hardening of the infiltration of carbon to make steel, a hardened layer from the surface to the appropriate depth. Hardening depth, meticulous organization, appropriate hardness of the surface and core hardness of the infiltration of carbon bearings, with excellent impact resistance than bearing steel bearing, the general chemical composition of the infiltration of carbon bearing steel.ball bearing
The NSK implementation of the vacuum degassing treatment, the materials used in clean high oxygen content of less good quality. And then using the appropriate heat treatment, and significantly improve the rolling fatigue life of be arings.
Addition to the above-mentioned steel, according to the special purpose, but also excellent heat resistance, high-speed steel, good corrosion resistance of stainless steel.china bearing
Cage material:
Stamping cage material, the use of low carbon steel. According to different purposes, but also the use of yellow copper, stainless steel plate. Cutting cage material, the use of high strength brass, carbon steel, in addition to the use of synthetic resin.miniature bearing
