The FAG AH series withdrawal sleeve is a fastening component used to mount and dismount bearings with a tapered bore on cylindrical shafts. It is placed between the shaft and the bearing, and allows transmitting the axial force needed to seat or release the bearing without damaging its raceways or the shaft. It is a key part in industrial maintenance tasks, where correct mounting defines the service life of the bearing and the precision of the assembly.

The designation of the AH series is read in blocks: the letters AH identify the withdrawal sleeve family; the first number indicates the shaft diameter for which the sleeve is intended, and the suffix G-H indicates design variants, such as the thread type or the dimensions of the threaded section. For example, AH39/500G-H, AH39/530G-H and AH39/560G-H correspond to different shaft diameters within the same series. To choose the correct code, the shaft diameter and the bearing to be mounted must be cross-referenced.

These sleeves are used in Argentine industries where large tapered roller bearings are mounted: steel, cement, mining, paper, flour mills and aggregate processing plants. They also appear in gearboxes, presses, ball mills and lifting equipment. In maintenance, they allow a bearing to be removed without striking it or overheating it, which reduces the risk of premature failures and facilitates scheduled shutdowns.

To select the sleeve, verify the shaft diameter, the tapered bore diameter of the bearing and the thread pitch. During mounting, lubrication of the thread and contact surfaces is essential to achieve a uniform fit; force should be applied axially and in a controlled manner, without impacts. Alignment between shaft and bearing must be checked before tightening, and the sleeve must be clean and free of burrs.

Withdrawal sleeves are marketed under different names depending on the manufacturer, but they keep the function of fastening and releasing tapered roller bearings. When looking for equivalents, the main dimensions and thread type must be compared, not just the code. At MR Accesorios Industriales we supply the FAG brand as part of our fastening and retention offering, and we can guide you to find the sleeve that fits your equipment.
