Adapter sleeves are using for locating bearings with a tapered bore onto a cylindrical seating as they can be used on smooth or stepped shafts. They are easy to mount and require no additional location on the shaft.

Extraction (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 endplates 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.

Materials:

The materials are carbon steel with a tensile strength at least 430N /mm2.

Dimensions:

The dimensions are in accordance with ISO 2982-1: 1995; Except the bore diameter of metric sleeves for inch shafts.

The dimensions are in accordance with ANSI/ABMA Std. 8.2-1991.

Tolerances:

The bore diameter of adapter sleeves is to tolerance JS9, the width to h15.

The tolerances of adapter sleeves with inch dimensions are in accordance with ANSI/ABMA Std. 8.2-1991.

Our supplies Lock nuts, Locking washers, Locking clips and Locking plates in a wide range of sizes also, they are also used as shaft or extraction nuts, depending on their usage. They are used to locate bearings and other components onto a shaft as well as to facilitate mounting bearings on tapered journals and dismounting bearings from extraction sleeves.
