Bearing lock washer for American Crane 9310

The bearing lock washer, identified by part number 801478, serves as a critical interface component within the mechanical assemblies of American Crane equipment. Its primary function is to provide a secure and uniform seating surface for bearings, which helps distribute operational loads and maintain precise alignment during machine movement. By ensuring the bearing remains correctly positioned, this component supports the overall stability of the assembly in which it is installed.

This component is compatible with American Crane models 9310 and 11250, including units identified by serial numbers 0180-A-02306 and GS 18072. It is typically utilized in high-load areas such as the slewing system, hoist mechanisms, or undercarriage assemblies where bearing performance is essential to the operation of the crane. The washer is engineered to meet specific dimensional tolerances required for these heavy-duty applications.

In mechanical systems, bearing washers act as spacers or load-bearing surfaces that prevent direct metal-to-metal contact between the bearing and other machine components. By maintaining the intended clearance and preventing axial movement, these washers help minimize friction and heat generation, which protects the bearing from premature wear and ensures the mechanical integrity of the rotating assembly during operation.
