Whosale High Quality 10mm, 80mm Bearing Steel Ball, G20, G40

Description of steel ball

The precision (spherical error) of rolling bearing ball has reached the field of ultrafine meters, and the requirements of material and manufacturing process of ball are also improving. The material of the ball is high carbon chromium bearing steel (vacuum degassing); Stainless steel (G95Cr18, G102Cr18Mo);Engineering ceramics (silicon nitride, silicon carbide, alumina); Of course, there are other kinds of material balls, such as carbide, glass, plastic, carbon steel balls and so on. More special ball has porous ball, hollow ball, ball mill ball, polishing device ball and so on, porous ball is used in the putter, ball valve, etc.; Hollow ball used in aircraft engines; Ball mill used for pigment, ferrite, food grinding; Polishing ball is used for surface polishing of aluminum die casting and deburring of casting and stamping parts.

High requirements for smelting quality of bearing steel, and the content and distribution of sulfur, phosphorus and non-metallic inclusions need to be strictly controlled, because the content and distribution of non-metallic inclusions have a great impact on the life of bearing steel. The basic quality requirements for bearing steel are purity and uniform organization. Purity means that there are fewer impurity elements and non-metallic impurities, and the uniform structure means that the carbides in the steel should be fine and evenly distributed. The higher the amount of inclusions, the shorter of the life span. In order to improve the quality of smelting, electric furnace smelting and electroslag remelting have been used recently, and new processes such as vacuum smelting and vacuum consumable refining can also be used to improve the quality of bearing steel.

GCr15 steel has low alloy content and good performance. It is currently the most widely used bearing steel. After quenching and low temperature tempering, it will have relatively high hardness and uniform structure of good performance. This kind of steel the cold working plasticity is general, the welding performance is poor, the sensitivity to the formation of white spots is large, and it has temper brittleness.

The company has a complete and scientific quality management system, strong technical force and strong production lineupo. the compang has high-end production equipment, precision testing instruments, including cold pier machine, vertical ball grinder, heat treatment equipment. we can provide steel balls of various varieties and specifications ranging from 0.5mm-150mm with product accuracy between 16 and 100. it is an ideal matching for aerospace industry, automobile industry, precision instruments, intrument toys, motorcycle bicycles, bearings, medical devices and food machinery , as well as puncture decoration and other industries products.
