Editrice NMB import bearing a few of the more important parts material and performance NMB imported bearings of the main products are precision miniature ball bearings, all kinds of high precision machinery, electronic components, etc. As miniature bearing industry in the world's largest manufacturer, since 1951, successively introduced all kinds of precision bearing, widely used in the VCR, air conditioner, vacuum cleaners, auto motor. Import bearings NMB is primarily a single-row radial deep groove ball bearing. In addition to open, the radial deep groove ball bearing with dust cover and seal type, can effectively reduce the foreign matter invasion and grease leakage. In addition, there are easy to install the flange and the retaining ring, and extremely thin axial and radial ball bearings, ball bearings and shaft, shell cover, bearing structure of the guide bearing, etc. 1) 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. 2) Cage materials required by the performance: good dimensional stability, mechanical strength. In addition, also need 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 import bearings NMB materials 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) Ring, rolling body materials required by the performance: rolling fatigue strength, high hardness, high wear resistance.
