The FAG H series adapter sleeve mounts bearings with a tapered bore onto cylindrical shafts. The assembly includes a split sleeve plus a lock nut and lock washer, so you can set the bearing position precisely and remove it without damaging the seat. It is a standard retention component in rotating equipment and power transmission drives, where correct mounting protects the bearing and the shaft.

Read the code from left to right: the H is followed by digits that identify size and taper type. An X suffix marks a taper variant; without a suffix, the taper is standard. Examples across the range include H2344X, H2348X, H2352X, H2356X, H3044X, H3052X, H3144X and H3148X. The digits after the H relate to the shaft diameter, so the same bearing bore can call for different sleeves depending on the shaft you are fitting.

These sleeves appear wherever tapered-bore bearings need reliable location: machine tools, centrifugal pumps, fans, conveyor drives and mining equipment. You will find them in food processing, cement, steel and oil and gas plants, and in the maintenance of gearboxes and large electric motors. The split design lets the sleeve compress against the shaft as the nut is tightened, which simplifies radial adjustment and later disassembly.

To select the right sleeve, confirm three things: shaft diameter, bearing bore taper and lock nut type. Before mounting, check shaft alignment and clean the contact surfaces. Lubricate the thread and the tapered seat so the nut turns smoothly and the surfaces are not scored. Tighten the nut with the lock washer tab engaged in the nut slot, then verify that the bearing runs without vibration.

Adapter sleeves are made to international standards, so dimensions are generally interchangeable between brands. Even so, compare the complete designation and the manufacturer's tolerances before substituting a part. FAG, which MR supplies, is one option in this segment. When in doubt, send the full part number and we will confirm what fits.
