Bearing material, which has several?
Bearing materials:
Rolling bearing rings and rolling elements, one side repeatedly withstand high contact pressure, the dry side accompanied by a rolling contact bearing slide. Holder, one side lined with rings and rolling elements, or a party in sliding contact with the side under tension and compression forces. Therefore, the bearing rings, rolling elements and cage materials, performance, the main requirements are as follows.
Rings, rolling the required material properties:
Rolling fatigue strength and hardness high wear resistance high cage desired material properties:
Dimensional stability, good mechanical strength also need processing Bearing Factory Jiashan good. Depending on the application, as well as requirements for impact resistance, heat resistance, good corrosion resistance.
Rings and rolling elements of the material:
Rings and rolling typically use carbon chromium bearing steel. Most of the bearings, the use of JIS steel ball bearing species of SUJ2. Large bearings SUJ3.
SUJ2 chemical composition, in the world, as a bearing material has been normalized. For example: With AISL52100 (United States), DIN100Cr6 (West Germany), BS535A99 (UK), etc. are the same kinds of steel.
Without further need for impact resistance as a bearing material chrome steel, chrome molybdenum steel, nickel-chromium-molybdenum steel, the use of carburizing hardening, the steel from the surface to the proper depth of a hardened layer. With appropriate hardening depth, fine tissue, suitable surface hardness and core hardness of carburizing bearing steel bearing than the bearing has excellent impact resistance, the chemical composition of the general carburizing bearing steel.
NSK embodiment of the vacuum degassing treatment, therefore, the material used in clean high oxygen content of less good quality. And then using the appropriate heat treatment, the rolling fatigue life of the bearing capacity improved significantly.
Addition to the above steel according to specific uses, the use of high-speed steel having excellent heat resistance, excellent corrosion resistance of stainless steel.
Cage Material:
Stamping cage material, the use of low carbon steel. Depending on the application, but also the use of brass, stainless steel plate. Cutting cage materials, the use of high strength brass, carbon steel, in addition, also uses a synthetic resin.
