Withdrawal sleeves

The withdrawal sleeve is a tapered sleeve with an external thread used to mount tapered bore bearings on cylindrical shafts, and especially to remove them without hammering or marking the shaft. A lock nut is threaded onto the sleeve thread and, when tightened against the inner ring, the sleeve is pulled out of the bearing bore. It is the usual solution on stepped shafts of transmissions, fans, pumps and gearboxes.

The series shown in the catalog are AH and AHX, with part numbers such as AH208, AH2308 or AHX 2310. The number combines the bearing dimension series with a size code: the last two digits, multiplied by 5, give the bearing bore in millimeters, for example 40 mm for size 08. It is not the shaft diameter. Each brand writes the code differently, with or without a space (AH 2308, AH2308), and sometimes adds suffix letters as in AH 2313 G.

To select it, start with the bearing: its designation, tapered bore and thread. Use the sleeve of the series that corresponds to that bearing, because the diameter, taper and thread change between series and sizes. The lock nut and lock washer are quoted separately and should be checked together with the sleeve, like the rest of the unit.

At MR we work with withdrawal sleeves from FAG, BGL, Timken, SKF, NTN and NSK. Send us the sleeve part number or, if you don't have it, the bearing designation, tapered bore and a photo of the mounted part, and we will indicate the equivalent. Request a quote by part number at MR via WhatsApp or email and we will respond promptly.
