Hydraulic Adapter Sleeve

The hydraulic adapter sleeve is the part that allows mounting and dismounting bearings with a tapered bore on cylindrical shafts, by applying oil pressure between the contact surfaces. It is selected by the shaft diameter, the tapered bore diameter of the bearing, and the mounting method the assembly accepts. In the catalog there are 26 references, all from SKF, including the code OH 3168 H.

The OH..H series identifies hydraulic adapter sleeves: the prefix OH corresponds to the line of mounting sleeves with an oil injection duct, and the suffix H indicates the variant with metric thread and built-in hydraulic nut. The intermediate number is related to the size of the bearing for which the sleeve is intended. These sleeves are used with hydraulic nuts and manual pumps that generate the necessary pressure to expand the part and facilitate the fit.

Typical applications are spherical roller bearings, tapered roller bearings and thrust bearings mounted on tapered shafts in transmission equipment, mills, pumps, fans and heavy machinery. The hydraulic adapter sleeve avoids impacts and heating during mounting, reduces the risk of damaging the shaft and the bearing, and allows repeating the dismounting operation without deteriorating the seating surfaces.

To request a quote for a hydraulic adapter sleeve you need the full part number, for example OH 3168 H, or the data of the bearing to be mounted: designation, tapered bore diameter, shaft diameter and mounting type. If you don't have the code, indicate the equivalence or the dimensions of the assembly and we will identify it. You can also inquire about the hydraulic nut and the injection pump used with each sleeve.
