Withdrawal sleeves DIVERS AHX310

The AHX310 pull-off sleeve (45 x 55 x 35 mm) is designed for the secure fitting and easy removal of tapered roller bearings on cylindrical, metric shafts with a 1:12 taper.

The AHX310 pull-off sleeve enables the mounting of roller bearings with a tapered internal bore onto cylindrical shaft journals. With a bore of 45 mm, an external diameter of 55 mm and a width of 35 mm, this fastening element complies with the standard metric design. The component is pressed axially between the shaft and the bearing inner ring, thereby creating the bearing seat. This system offers practical advantages for maintenance and servicing, as the press fit can be released in a controlled manner during disassembly using a suitable slotted nut.

How is the AHX310 pull-off sleeve fitted onto the shaft?

The AHX310 pull-off sleeve is primarily used for bearings mounted on stepped shafts with a shaft shoulder. The sleeve, with a taper ratio of 1:12, allows the required radial clearance of the bearing to be adjusted during press-fitting. The design is suitable for machines and drives with cylindrical shaft sections. As the inner ring of the bearing is axially supported against the fixed shaft shoulder, the axial position remains stable, whilst subsequent disassembly can be carried out without damaging adjacent components.

What should be borne in mind regarding accessories and the 1:12 taper?

When using the AHX310 pull-off sleeve, precise alignment with the shaft and the appropriate fitting accessories are essential. The sleeve is designed for metric shaft diameters of 45 mm. As per the scope of delivery, the sleeve is supplied without a retaining plate or groove nut. These parts are selected separately to match the shaft and sleeve threads. Clean contact surfaces on the shaft and bearing bore ensure that the sleeve is drawn in evenly without unwanted distortion.
