Applications
Leaded bronze ASTM B584 C93200 is used for general-purpose bearings and bushings, including machine-tool spindle bearings, crane bearings, diesel-engine wrist-pin bushings and rolling-mill bearings. Further applications include pump fixtures and thrust washers. Other cast components used in this material family include plain bearings 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.
