BEARINGS & CONSUMABLES

Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on plain or stepped shafts. They are easy to install and require no additional location on the shaft.

When adapter sleeves are used on plain shafts, the bearing can be located at any position on the shaft. When used on stepped shafts together with an L-shaped spacer ring, bearings can be accurately positioned axially thereby facilitating bearing mounting and dismounting.

Withdrawal sleeves can be used to mount bearings with a tapered bore on 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. Lock nuts or end plates are not supplied with withdrawal sleeves. KM or HM lock nuts  with appropriate locking devices are suitable, but must be ordered separately.

To press the withdrawal sleeve into the bearing bore, a considerable amount of force is required to overcome the friction between the bearing, sleeve and shaft. To facilitate mounting and dismounting bearings on withdrawal sleeves, we  recommend using a hydraulic nut.
