-. Withdrawal sleeve (AH)

Withdrawal sleeves can be used to mount bearings with tapered bore on cylindrical seating’s 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. The sleeves are slotted and have an external taper of 1:12 or 1:30.

-. Withdrawal sleeves for oil injection (AOH)

These AOH sleeves have two oil supply ducts at the threaded side as well as oil distributor grooves in the circumferential and axial directions, both in the outside surface and the sleeve bore. If oil is injected through these ducts and grooves, an oil film is formed between the mating surfaces of the bearing and sleeve and between the shaft and sleeve, and the force required to mount the bearing is considerably reduced.
