Withdrawal Sleeves

Features:
Withdrawal sleeves can be used to mount bearings with a tapered bore on cylindrical seats 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 end plates are not supplied with the extraction sleeves. KM or HM lock nuts and respective locking washers are suitable but must be ordered separately. Further information will be found in the section "Lock nuts with locking washer or clip". To secure the bearing to the shaft, press the extraction 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 extraction sleeves can be facilitated considerably by using a hydraulic nut.

Withdrawal sleeves are used for mounting tapered bearings on to the cylindrical shafts. They facilitate easy mounting, securing and dismounting. They are suitable for both smooth and stepped shafts. Bearing sleeve can easily adapt to the shaft diameter. They are usually coated with a preservative, are slotted and have an external taper. This allows the sleeve to be used with wide spherical roller bearings. Withdrawal sleeves for oil injection have oil ducts and distribution grooves, on the threaded side.
