What are the structural components of ball bearings? Many customers are curious about the structure of ball bearings. The editor was also curious about the small ball before. Now I will introduce how ball bearing manufacturers make ball bearings. Ball bearings are mainly composed of four basic components: balls, inner rings, outer rings and cages, also called cages or retainers. General industrial ball bearings meet the AISI 52100 standard. The balls and rings are usually made of high-chromium steel, and the Rockwell C-scale hardness is about 61-65. The hardness of the cage is lower than that of the ball and the ring, and its material is metal (such as: medium carbon steel, aluminum alloy) or non-metal (such as: Teflon, PTEF, polymer material). Ball bearings have less rotational friction resistance than journal bearings, so at the same speed, the temperature generated by friction will be lower. Founded in 1985, the company is a manufacturer specializing in precision ball bearings and ball bearings. If you are looking for a professional ball bearing manufacturer, choose Sanli.
