Withdrawal sleeves can be used to mount bearings with a tapered bore on the cylindrical seat of stepped shafts (). The sleeve is pressed into the bore of the bearing inner ring, which abuts a shaft shoulder or similar fixed component. The sleeve is located on the shaft by a nut or an end plate. Lock nuts or end plates are not supplied with withdrawal sleeves. KM or HM lock nuts (→ ) with appropriate locking devices are suitable, but must be ordered separately.

To press the withdrawal sleeve into the bearing bore, a considerable amount of force is required to overcome the friction between the bearing, sleeve and shaft. To facilitate mounting and dismounting bearings on withdrawal sleeves, SKF recommends using a hydraulic nut ().
