Bearing lock nut for American Hoist 11250

The 801465 bearing lock nut is a fastening component designed to secure the axial position of bearings on a shaft or within a machine housing. Unlike standard nuts, this component features a mechanism to prevent loosening from vibrations, impacts, or dynamic loads encountered during crane operation. It is specifically engineered for use in bearing assemblies where maintaining precise axial positioning is necessary for the stability of rotating components. This part is compatible with American Hoist 11250 and 9310 machinery models.

Lock nuts of this type are typically designed with slots or a collar to interface with a locking washer or pin, which prevents rotation once installed. Proper thread precision is required to achieve the specified torque, ensuring the bearing remains in its correct axial position without excessive play or improper preload. In heavy machinery, these nuts are used in various assemblies, including transmission shafts, cable drums, and slewing systems. By preventing axial displacement, the lock nut helps avoid bearing misalignment, excessive heat generation, and premature wear within the mechanical system.
