When a bearing with a tapered bore has to come off the shaft without scoring the seat or the inner ring, the SKF AOH G series withdrawal sleeve is the component that makes it possible. It mounts on the shaft and, with a precision lock nut, provides a controlled way to extract the bearing. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America.

Reading the AOH G code helps you match the sleeve to the bearing. The letters AOH place it in the withdrawal sleeve family. The first numeric group, such as 23, 30 or 31, points to the bearing series. The two digits that follow are a size code; multiply them by 5 to get the bearing bore in millimeters. The G at the end denotes a design variant, usually tied to the thread type or the sleeve's execution. You can see this pattern in references like AOH 2352 G, AOH 3044 G and AOH 3176 G: the numbers shift with the size, while the G stays.

These sleeves appear wherever tapered-fit bearings are used on the shaft: rolling mills, cement plants, mining operations, paper machines, cranes and heavy transmission equipment. Maintenance crews rely on them in gearboxes, mills, presses and large machinery, where pulling a bearing without harming the shaft is essential. Repair shops that rebuild equipment with spherical or cylindrical roller bearings with a tapered bore also keep them on hand.

Selection comes down to the bearing bore diameter and taper, plus the nut you plan to use for extraction. The G suffix typically signals a metric thread or a particular execution, so confirm it against the bearing data sheet. Before mounting, lubricate the thread and the tapered surface, then apply extraction force axially and evenly. Inspect the sleeve for burrs or thread wear before reusing it.

Other manufacturers may use their own names for withdrawal sleeves that serve the same purpose. Interchangeability is not decided by the part number alone; the tapered bore dimensions, thread and useful length all matter. Comparing drawings or checking with a supplier is the safer route. If you send us the bearing part number and shaft dimensions, we can help you sort out the right reference.

If you already know the sleeve or bearing part number, send it to MR Industrial Accessories LLC by WhatsApp or email and we will quote the SKF AOH G series reference you need. We can also advise on the nut and the mounting procedure for your equipment.
