Withdrawal sleeve AHX312 provides a mounting interface for transferring bearings with a tapered bore onto a cylindrical shaft seat, allowing axial clamping without requiring the shaft itself to be tapered. The bore diameter is 60.0 mm, the sleeve mass is 202.44 g, and the design corresponds to the standard execution of the AH series. The sleeve is drawn up over the shaft using the locknut and pulled under the bearing bore, creating a controlled interference fit through axial displacement. This allows precise control of the radial internal clearance reduction during mounting, which is relevant for applications where the bearing is fitted on a plain shaft end rather than a stepped or tapered journal. As a finished mechanical part, it requires no further machining before installation.
