The AH series withdrawal sleeve is a fastening component used together with tapered bore bearings to seat them on tapered shafts and, above all, to remove them without damaging the bearing or the seat. It threads onto the shaft end thread and, when turned, pushes the bearing outward. MR Accesorios Industriales sells the NSK AH series in Buenos Aires, Argentina.

The AH series designation is read with the number that follows the letters: it identifies the sleeve size and the tapered shaft it works with. In the examples of the series, AH 2308 and AH 2309 correspond to sleeves for bearings of the 23 series, while AH 24024 and AH 24026 do so for the 24 series. The suffixes and variants that appear in the NSK catalogue indicate thread or length adaptations, so it is always best to request a quote with the complete part number.

In Argentine industry these sleeves appear in gearboxes, conveyor belts, mills, pumps and process equipment where tapered bore bearings are mounted. They are also used in maintenance at steel plants, cement plants, paper mills and in workshops that recondition shafts. As a dismounting part, it is common to order it together with the bearing to be removed, to ensure that the thread and diameter match the shaft.

To choose the correct sleeve you must start from the mounted bearing: its designation defines the series and the tapered bore diameter. The sleeve must thread onto the shaft thread without forcing and rest evenly on the inner ring. Before using it, clean the thread and lubricate the thread so that the extraction force is uniform. If the bearing is very tight, apply controlled heat or a hydraulic tool, never direct blows on the cage.

As for equivalents, other manufacturers use their own designations for withdrawal sleeves of similar function, but the part number does not always match. When the customer brings a part number from another brand or an unidentified part, at MR Accesorios Industriales we cross-reference it with the NSK AH series and tell you the equivalent reference. Interchangeability depends on the thread, diameter and length, so it is not advisable to replace by approximation.

If you need an AH series withdrawal sleeve, send us the bearing part number or the tapered shaft size by WhatsApp. At MR Accesorios Industriales we quote the exact part number or size you request and reply promptly. You can also ask us about other mounting and dismounting parts to complete the job.
