Applications
Leaded bronze ASTM B584 C93700 is used for high-speed, heavily loaded bearings and bushings, including large ship bearings. Other documented applications include pump parts, impellers and slide guides for steel mills. Other cast components used in this material family include plain bearings, thrust washers and sliding-contact wear parts.
Typical settings include machine tools, pumps, heavy equipment and machinery maintenance. Grade-specific load and speed limitations, lubrication and mating-surface conditions must be retained, particularly for grades intended for lightly loaded bearings.
