Bushing for Bucyrus 4100XPCAC

The R82321D14 bushing acts as a sliding bearing within the mechanical assemblies of heavy mining equipment. By providing a controlled interface between moving parts, it facilitates smooth rotation or sliding motion while protecting primary structural components from direct contact. This component is engineered to maintain precise alignment within the pivot points of the machine, supporting the operational requirements of large-scale mining shovels.

This part is compatible with Bucyrus 4100XPCAC, Bucyrus 7495HR2, P&H 4100XPCAC, and P&H 7495HR2 models. It is installed in systems where mechanical linkages or pins are subject to constant motion and load. Proper fitment and adherence to dimensional tolerances are necessary to ensure the component functions correctly within the assembly.

In heavy machinery, bushings are used to manage friction at pivot points, such as those found in the boom, dipper arm, and bucket linkages. By absorbing the wear that would otherwise affect more expensive shafts or housings, these components allow for easier maintenance of the machine's movement systems. They are often designed to accommodate lubrication, which helps manage heat and friction during operation.
