Withdrawal Sleeves

Withdrawal sleeves can be used to mount bearings with a tapered bore on cylindrical seatings of stepped shafts.

The sleeve is pressed into the bore of the bearing that 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 endplates are not supplied with the withdrawal sleeves. KM or HM lock nuts are suitable but must be ordered separately.

To secure the bearing to the shaft, press the withdrawal sleeve into the bearing bore. To do this, particularly where larger bearings are concerned, considerable force is required to overcome the friction between the mating surfaces of the bearing and sleeve and of the sleeve and shaft.

Mounting and dismounting of bearings on withdrawal sleeves can be facilitated considerably by using a hydraulic nut.
