Withdrawal sleeves can be used to mount bearings with a tapered bore onto 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. KM or HM lock nuts with appropriate locking devices are suitable.
Recommends using a hydraulic nut to press the withdrawal sleeve into the bearing bore, as a considerable amount of force is required to overcome the friction between the bearing, sleeve and shaft.
