The so-called bearing is subjected to extreme pressure and friction during operation, so the bearing steel is required to have high and uniform hardness and wear resistance and a high elastic limit.
The requirements for the uniformity of the chemical composition of the bearing steel, the content and dispersion of non-metallic luggage tie rod steel ball inclusions, and the dispersion of carbides are very strict. Bearing steel, also known as high carbon steel, has a carbon content of 1%. The weight Wcr of the guide rail steel ball is 0.5%-1.65%. Bearing steel is divided into six categories: high-carbon bearing steel, non-carbon bearing steel, carburized bearing steel, stainless bearing steel, medium and high temperature bearing steel and antimagnetic bearing steel.
Use of steel balls: Bearing steel balls are widely used in high-speed and low-noise bearings, bicycles, motorcycles, cars, slide rails, universal balls, luggage, electronic industry, and can also be used to grind other media.
The characteristics of the steel ball: the hardness reaches HRC62-65 degrees, the material has good wear resistance, the precision can reach one ten thousandth of a millimeter after cold processing into the steel ball, and the surface is mirror-like. The color is chrome, but it cannot be welded.
Classification of steel balls: high-precision steel balls, wear-resistant steel balls, and ground steel balls.
