Adapter sleeve H2338 transfers load between a shaft of standard cylindrical form and a bearing bore machined with a taper, allowing the bearing to be mounted at any point along the shaft rather than at a shoulder or fixed step. The bore diameter of the sleeve is 170.0 mm, the net mass is 13.176 kg, and the design corresponds to the standard execution FAG offers for this size. Mounting on the adapter sleeve is done mechanically, with the locknut drawn up to achieve the required interference fit and internal clearance reduction of the bearing during installation. This construction simplifies removal and replacement of the bearing without requiring precision-ground shaft seats, and it accommodates a plain, unstepped shaft section machined to standard tolerance. Correct fit-up depends on following the mounting instructions for driving distance or clearance reduction specified for the corresponding bearing bore size.
