For mounting a bearing with a tapered bore onto a cylindrical shaft, the NTN H series adapter sleeve provides a practical answer. Each unit combines a split sleeve with a lock nut and lock washer, so the bearing can be set precisely and taken apart without difficulty. Concentric running and resistance to axial movement depend on this interface, which makes the sleeve an important detail in power transmission assemblies. MR supplies this series with the application support needed to get the fit right.

Reading the H designation is straightforward once you know the pattern. The letter H is followed by a number tied to the shaft diameter and the bearing size. Take H 220X, which fits a bearing with a 100 mm tapered bore, or H 308X, which fits a 40 mm bore; in each case the shaft is smaller than the bore. The X suffix marks a particular dimensional variant. When you compare H 309X, H 310X, H 311X, H 312X and H 313X, the number rises along with the shaft diameter.

These sleeves appear in food processing, metallurgy, mining and cement operations, among other sectors. Gearboxes, conveyors, mills, pumps and fans rely on them wherever a bearing has to sit on a cylindrical shaft and stay firmly in place. Plants running continuous processes, where bearings are serviced and swapped regularly, also use them often. The NTN H series gives these situations a standardized mounting option.

Choosing the right sleeve starts with two figures: the shaft diameter and the bearing number it will serve. Confirm the taper of the bearing bore and the lock nut type as well. At assembly, clean the mating surfaces thoroughly and apply a suitable lubricant to ease fitting. Alignment and nut torque deserve close attention, since getting them wrong can lead to early failure. Our technical team is available if you want help working through the details.

On interchangeability, NTN H series adapter sleeves can be swapped with those from other manufacturers that work to the same dimensional standard, including SKF, FAG and NSK. Even so, it pays to check tolerances and the specific design before substituting a part. What determines whether one sleeve replaces another is the shaft diameter and the bearing number, not the brand's part number. Send us the original part number and we will identify the compatible alternative.
