tin, GOST 1320-74, grade B83S. B83S is a bearing alloy whose main components are tin, antimony, and copper. It belongs to the group of antifriction materials. It is supplied in blocks with a trapezoidal cross-section and is used for casting plain bearings. Each bar has a melting number. Each bar has a brand and trademark of the manufacturer. B83S is used exclusively for filling bearings of high-power machines. These types of bearings are used in steam turbines, turbo compressors, high-power diesel engines, electric motors, and other engineering products. |
