How the quality of bearing

Bearing quality bearing is precision standard parts in the mechanical equipment. Bearing on the normal operation of the machine equipment, service life and processing quality plays an important role in many aspects, such as. At present, the domestic production of bearing numerous business and bearing company, various brands, different class and bearing of fake and shoddy products on the market is very active, many manufacturing enterprises when choosing bearing authenticity shape, disoriented. Bearing sold on the market is more optimistic, so the quality of the bearing has how is the quality of material in the market by users, below we together to learn the quality of the bearing are considered? Bearing application materials: 1) Ring, rolling body materials required by the performance: rolling fatigue strength, high hardness, high wear resistance, 2) Cage materials required by the performance: good dimensional stability, mechanical strength and good workability. According to different purposes and demands of its, impact resistance, heat resistance, good corrosion resistance. 3) Ring and rolling body material: ring and rolling body usually use high carbon chromium bearing steel. Most of the bearing, using JIS SUJ2 steel grade. The chemical composition of SUJ2, around the world, as a bearing material has been normalized. For example: with AISL52100 ( The United States) DIN100Cr6 ( West Germany) BS535A99 ( The UK) All belong to the same steel. The steel grade, according to the special purpose, also use the excellent heat resistance of high speed steel, good corrosion resistance of stainless steel. 4) Cage materials: stamping materials, use of low carbon steel. According to different purposes, also used brass, stainless steel plate. Cutting system maintains a material, the use of high-intensity brass, carbon steel, and also the use of synthetic resin. Above is the combination of bearing using materials quality, a good bearing brand lies in its quality assurance, bearing is a very humble in life movement components, but he is closely related to our life. The existence of NMB bearing gives users a lot of convenience, because 'it' infinite machinery, mechanical operation of the let our carefree! ！
