Introduce NMB brand of ball bearing components and performance! Ball bearing is a kind of rolling bearings, the spherical alloy steel ball, steel ring and the outer steel ring in the middle of the installation, to scroll way to reduce the friction in the process of power transfer to and improve the efficiency of mechanical power transmission. Ball bearing can't bear the heavy load of larger, more common in the light industry machinery. Ball bearing is also called the ball bearings. Ball bearing components: ball bearing consists of four basic components: the ball, the inner ring and outer ring and retainer. General industrial standard of ball bearing satisfy AISI52100, ball and ring usually are made from high chromium steel, rockwell hardness in 61 - 65. The hardness of ball bearing performance: the retainer compared to low ball and ring, its material with metal ( Such as: medium carbon steel, aluminum alloy) Or non-metallic ( Such as: iron, dragon, PTEF, polymer materials) 。 Rolling bearing is smaller than the rotation of the shaft bearing friction resistance, so the same speed, the temperature will be lower because of friction. Ball bearings are generally used in low load of mechanical equipment. Because of ball bearing load bearing area is small, appear easily in the case of high-speed serious mechanical damage, so often adopted in the heavy load of mechanical needle bearing to increase the bearing surface, and improve the efficiency of mechanical transmission, at the same time reduce the mechanical damage. Ball bearing has changed the way of bearing friction, adopts rolling friction, this way is more effective in reducing the friction between the bearing surface phenomenon, improve the service life of the fan bearing, thus to extend the service life of the radiator. Defect is process is more complex, higher cost, but also bring higher noise.
