Common material composition of various parts of self aligning ball bearing
Clicks:14088 Date:12-2
Self aligning ball bearing ring and steel ball, one side repeated high contact pressure, one side of the same sliding rolling contact. A cage, one side with a ring and a rolling body, or a sliding contact with one of them, is subjected to tension and contractile force. Therefore, the material and performance requirements for bearing rings, steel balls and retainers are as follows:
The performance of the first, bearing ring and ball materials required: rolling fatigue strength, high hardness, abrasion resistance.
Second, the performance required by the cage material: good size stability and large mechanical strength.
In addition, it is necessary to have good processing. According to the different uses of the bearing, it is also required for its impact resistance, heat resistance and corrosion resistance.
Self aligning ball bearing rings and steel ball materials: high carbon chromium bearing steel is usually used in rings and steel balls. Large bearing, using SUJ2 in JIS steel. SUJ3 is used for large bearing.
In all countries of the world, materials used as bearings have been standardized. For example, AISL52100 (USA), DIN100Cr6 (West Germany), BS535A99 (UK) and so on belong to the same kind of steel.
To further impact conditions, as bearing material with steel, chrome molybdenum steel, nickel chromium molybdenum steel, take the infiltration of carbon quenching, the steel from the outside to the appropriate depth of a softened layer. The carbon bearing with proper softening depth, fine microstructure, suitable hardness and hardness of the surface has excellent impact resistance than those bearing steel bearings, and the chemical composition of some carbon bearing steel is excellent.
In addition to the above steel, according to the special use of the bearing, the high speed steel with excellent heat resistance is also used, and the corrosion resistant stainless steel is good.
The material of the cage: the material of the stamping cage, and the use of low carbon steel. According to the different use, also use the brass plate, stainless steel plate. The material of the cage is cut, the high strength brass, carbon steel, and the decomposition resin are also used.
