Bearing Bronze
Bearing Bronze is a group of high-leaded tin bronze alloys, widely recognized for their excellent wear resistance, corrosion resistance, and reliable performance in industrial applications. These alloys are primarily used in bearings and bushings that operate under moderate-to-high loads and speeds. At Sayverse, we offer various grades of Bearing Bronze, including C84400, C83600, C93200, C93500, C93700, C93800, and C93900, designed to meet the unique demands of different industries such as electric motors, machinery, pumps, and hydraulic systems.
