Applications
Leaded bronze ASTM B584 C94300 is used for high-speed bearings carrying light loads, along with soft bushings and related bearing components. Railway applications are also documented. 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.
