The SKF withdrawal sleeve is a tapered sleeve inserted between the shaft and the tapered bore of the bearing. Unlike an adapter sleeve, it enters from the opposite side and the bearing rests against an abutment on the shaft. Its advantage lies in dismounting: a nut screwed onto the sleeve itself withdraws it and releases the bearing without blows.

In AH 309, the letters name the series and the digits refer to the bearing it carries, with dimension series and size. They are not the shaft diameter. AHX 310 belongs to a similar series with a different withdrawal thread, so it takes another nut. Both are used the same way, but they are not interchanged without checking that thread.
AOH 2238 is from the series with ducts for oil injection, intended for large sizes: oil under pressure separates the surfaces and the sleeve comes out with less effort. A letter at the end, as in AH 313 G, marks another execution of the thread. All of that is part of the reference.
To mount, the sleeve is pushed into the bearing bore until the fit is achieved, and it is secured with a nut or an end plate on the shaft. The bearing must rest against a shoulder or a spacer ring: without that abutment, the sleeve moves it instead of fitting it.
To dismount, a nut is screwed onto the sleeve thread and driven against the bearing. For large sizes a hydraulic nut is used. It is worth identifying that nut before the stoppage, because it is a separate part and its thread depends on the sleeve series.
Send us the complete designation of the sleeve and the quantity. If you do not have it, give us the bearing designation, which must end in K, and the actual shaft diameter. State whether the shaft has the abutment for the bearing and how the sleeve is secured at the end. If you also need the withdrawal nut, say so: it is chosen according to the sleeve thread.
No. It enters from the other side, needs an abutment on the shaft and is withdrawn with a nut.
Only if the withdrawal thread matches the nut you have. Check it first.
The withdrawal nut is a separate tool. It is ordered under its own designation.

The SKF AOH series withdrawal sleeve is a steel part that threads into the threaded bore of the shaft to facilitate the removal of bearings with a tapered bore. It is used when the bearing is mounted with interference and cannot be removed with conventional pullers. MR Accesorios Industriales sells this series, with sizes for different shaft diameters.
The SKF withdrawal sleeve of the AH series is a key part for removing bearings with tapered bore without damaging the shaft or the bearing. It is used in industrial maintenance tasks where clean and safe disassembly is a priority. MR Accesorios Industriales sells this line, backed in the field.
The SKF AOH G series withdrawal sleeve is a mounting and dismounting component for bearings with a tapered bore. It is placed on the shaft and, by means of a precision lock nut, allows the bearing to be removed without damaging the inner ring or the seat. MR Accesorios Industriales sells this line, backed in the industrial sector.
