Withdrawal Sleeves are often 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 components. The sleeve is located on the shaft by a nut or an end plate. Withdrawal sleeves give easier dismounting of the bearings, as the press fit of the bearing can be loosened with the aid of a Lock Nut applied to the withdrawal sleeve. KM or HM Lock Nuts with appropriate locking devices are suitable.

Our withdrawal sleeves are slotted and have an external taper of 1:12 except for the AH 240 and AH 241 series which have an external taper of 1:30 and are intended for using with wide bearings of 40 and 41 series.

With the same normal sleeves dimensions, Hydraulic Withdrawal Sleeves are recommended for shafts of large size sets because they are provided with oil injection gutters, making the assembling and disassembling much easier.

Lock nuts are not supplied with the withdrawal sleeves and must be ordered separately.
