The FAG AH-H series withdrawal sleeve is a component used to mount and remove tapered roller bearings on tapered shafts. It sits between the bearing and the extraction tool, enabling disassembly without harming the shaft or the bearing. In industrial maintenance, this sleeve supports clean, controlled removal that helps avoid extended downtime and unnecessary costs.

The AH-H code breaks down into three parts: AH indicates the withdrawal sleeve family, the following number matches the bearing bore in millimeters (the shaft diameter is smaller), and the -H suffix denotes the construction variant. Each complete part number corresponds to a specific size, so substituting by approximation is not recommended.

These sleeves are common in maintenance of tapered roller bearing equipment such as gearboxes, mills, presses, road machinery, material handling systems, and heavy drives. They are also found in repair shops and plants that need to dismount bearings without destructive methods. MR Industrial Accessories supplies this FAG line to customers across the United States and in several Latin American countries.

When selecting a sleeve, consider the bearing part number you plan to remove and the tapered shaft diameter. The sleeve must match that combination; a similar number is not sufficient. Before assembling the extraction device, check that threads and support surfaces are clean and free of burrs, and apply the recommended lubricant to ease disassembly. Proper alignment among sleeve, bearing, and puller prevents lateral forces that could damage the raceways.

FAG withdrawal sleeves may be interchanged with equivalent parts from other manufacturers that use the same standardized designation, but always confirm equivalence by part number and dimensions, not by visual similarity. Variants exist with and without the suffix, and with different threads or lengths. For replacement, compare the part number stamped on the sleeve with that of the associated bearing and verify before purchasing.

If you have the sleeve part number—for example, AH33/630-H, AH33/670-H, or AH33/710-H—send it by WhatsApp or email to MR Industrial Accessories and we will quote you promptly. You can also ask about other sizes in the AH-H series or the bearing you need to remove; with that information, we will help you get the correct part.
