Bearing cone shim for American Crane 7260

The bearing cone shim, part number 801495, is a precision component used to establish the correct preload or clearance within tapered roller bearing assemblies. By inserting this shim between the bearing cone and its seat, maintenance technicians can achieve the precise spacing required for the assembly to function within specified tolerances. This component ensures that the bearing operates with the correct amount of axial and radial play, which is necessary for the mechanical stability of the rotating assembly.

This shim is compatible with American Crane 7260 and American Crane RT-855B cranes, as well as Grove 7260 and Grove RT-855B models. It is commonly utilized in various mechanical systems throughout these cranes, including gearboxes, axles, and transmission assemblies where tapered bearings are required to manage combined loads. Proper selection and installation of shims are necessary to maintain the alignment and operational integrity of these heavy machinery systems.

In mechanical engineering, shims of this type serve as adjustment tools to compensate for dimensional variations in housing or shaft assemblies. They allow for fine-tuning the internal geometry of a bearing arrangement, preventing issues such as excessive play or binding that can occur if the bearing is not seated correctly. By maintaining the intended clearance, the shim helps ensure that the bearing assembly functions as designed under operational loads.
