For mounting a bearing with a tapered bore onto a cylindrical shaft, the NTN AH series withdrawal sleeve acts as the axial fixing element. It sits between the bearing and the lock nut and simplifies removal later without harming the fit. MR Industrial Accessories LLC supplies this sleeve within its range of bushings and sleeves.
The AH designation works as a reference code: the AH prefix is followed by a number that points to size and application. Sleeves such as AH 308, AH 309, AH 313, AH 314 and AH 315 are intended for 3xx series bearings, while AH 2236, AH 2238 and AH 2240 match 223xx series bearings. That number is not a direct dimension; always verify it against the bearing to confirm compatibility.
These sleeves are common in equipment where tapered roller bearings sit on cylindrical shafts: gearboxes, pumps, fans, conveyors and process machinery. They also show up when maintaining large rollers and pulleys. Because the bearing can be taken off without hammering, replacement work is easier and the shaft and bearing are less likely to be damaged.
Choosing the right sleeve starts with the part number of the tapered bore bearing you plan to mount. The AH series is selected for dimensional compatibility with that bearing. When mounting, make sure the tapered surfaces are clean, apply the correct lubricant and tighten the lock nut as the bearing manufacturer specifies. Alignment and controlled tightening matter for reliable operation.
NTN withdrawal sleeves can be interchanged with other brands that use the same standardized designation. If you have a part number from another brand, we can cross-reference it by equivalence. MR Industrial Accessories LLC quotes the exact part number you need and helps you confirm it fits your application.
To request a withdrawal sleeve, send the bearing or sleeve part number via WhatsApp or email. We reply promptly and can suggest a compatible alternative if required. We serve customers across the United States and in several Latin American countries.

Frequently asked questions
- How do I identify the withdrawal sleeve I need?
- Start with the part number of the tapered bore bearing you will mount. The sleeve is chosen for compatibility with that bearing. If the part number is not available, send the shaft and bearing dimensions and we will help identify it.
- Can NTN sleeves be used with bearings from other brands?
- Yes, withdrawal sleeves follow standardized designations, so they are often interchangeable between brands. If you provide a part number from another brand, we cross-reference it by equivalence to give you the corresponding NTN sleeve.
- What should I watch for when mounting a withdrawal sleeve?
- Clean the tapered surfaces, lubricate as appropriate and tighten the lock nut following the bearing manufacturer's recommendations. Avoid impacts and check alignment to prevent damage to the bearing or shaft.
