  GCR15 material 3 to 100mm D6mm bearing ball   5.5mm bearing ball:   Summary: Bearing in the work is under great pressure and friction force, so the required hardness and wear resistance of high and uniform bearing steel, and high elastic limit. The chemical composition of bearing steel, non uniformity of content and distribution of carbides, inclusions distribution and other requirements are very strict and high carbon chromium bearing steel steel, carbon content of Wc is about 1%, including Luo Wcr as 0.5%-1.65%. Bearing steel is divided into high carbon chromium bearing steel, bearing steel, chromium free carburizing bearing steel, stainless steel, high temperature bearing steel and antimagnetic bearing steel six categories.     Application: ball bearing is widely used in the high-speed low noise bearings, bicycle, motorcycle, car, rail, Wan Xiangqiu, bags, electronic industry, can also be used for grinding medium.   Properties: hardness can reach HRC62-65 degrees, the material with better wear resistance, cold processed into steel ball precision can reach 1/10000 mm, mirror surface is. Color for the chrome color, but can not be welded.     Classification: high precision steel balls, grinding balls, grinding ball.
