The AH series withdrawal sleeve is a mounting component used to mount bearings with a tapered bore onto cylindrical shafts. It is placed between the shaft and the bearing, and allows the radial clearance to be adjusted using a lock nut. MR Accesorios Industriales sells this NTN series, with sizes for bearings with a bore according to the part number. It is a key part in applications requiring precise mounting and damage-free dismounting.

The AH series designation is interpreted as follows: the letters AH identify the withdrawal sleeve, the number that follows is the bearing series number (for example, 240 in AH 24044H) and the last two digits, multiplied by 5, give the bearing bore in millimeters. For example, the AH 24044H is used with a bearing with a 220 mm bore, the AH 24048H with a 240 mm one and the AH 24056H with a 280 mm one. The H suffix indicates that the sleeve has a slot for the locking tab. The models AH 24144H, AH 24148H and AH 24152H correspond to bearings with a bore of 220, 240 and 260 mm respectively.

These sleeves are used in a wide variety of industries in Argentina, such as metallurgy, cement, mining and paper. They are common in grinding equipment, conveyor belts, centrifugal pumps and speed reducers. Their main function is to facilitate the mounting and dismounting of bearings on shafts where an interference fit is required, without the need for hydraulic presses. They are also used in applications where the bearing must be dismounted frequently for maintenance.

To select the right sleeve, take into account the shaft diameter and the type of bearing with a tapered bore that you are going to mount. It is essential to verify the compatibility of the thread and the sleeve length with the bearing. During mounting, make sure to clean and lubricate the contact surfaces, and to tighten the lock nut with the appropriate wrench until the recommended radial clearance is reached. The slot for the locking tab must match the one on the shaft to prevent rotation. Incorrect mounting can damage the bearing and reduce its service life.

As for equivalents, NTN AH series withdrawal sleeves are interchangeable with those of other brands that follow the same standardized designation. If you have a part number from another brand, you can ask us and we will tell you the equivalent reference. It is important to verify the critical dimensions, such as the shaft diameter and the thread, to ensure compatibility. Not all brands maintain exactly the same tolerances, so it is always advisable to confirm with our technical team.
