Withdrawal sleeves are suitable for mounting tapered bore bearings on stepped shafts with a cylindrical seat. The withdrawal sleeve is pressed into the bearings inner ring, the bearing should be installed against a fixed component, such as a shaft shoulder. A lock nut is used to secure the withdrawal sleeve on the shaft. Hydraulic nuts are used for larger bearings, where the mounting forces are significant during the installation, and ease the installation due to reduced friction.
◆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 (Lock nuts requiring a keyway) with appropriate locking devices are suitable.
