The NTN H series adapter sleeve is a mounting component used to secure bearings with a tapered bore onto cylindrical shafts. It consists of a split sleeve and a lock nut with a lock washer, which allows precise adjustment and easy disassembly. It is a key part in power transmission, as it ensures concentricity and prevents axial displacement of the bearing. MR Accesorios Industriales sells this series with the technical assistance each application requires.

The H series designation reads with the letter H followed by a number that indicates the shaft diameter and the bearing size. For example, H 220X corresponds to a sleeve for a 100 mm shaft and a bearing of the 220 series; H 308X is used with bearings of the 308 series. The X suffix indicates a specific dimensional variant. In the examples H 309X, H 310X, H 311X, H 312X and H 313X, the number increases with the shaft diameter. Learn more about this nomenclature by consulting MR Accesorios Industriales.

These sleeves are used in a wide variety of industries in Argentina, such as food, metallurgy, mining and cement. They are used in gearboxes, conveyors, mills, pumps and fans, where bearings must be mounted on cylindrical shafts and require reliable fastening. They are also common in continuous process equipment, where bearing maintenance and replacement are frequent tasks. The NTN H series offers a standardized solution for these applications.

To select the right sleeve, take into account the shaft diameter and the bearing number it will work with. It is essential to verify the taper of the bearing bore and the type of lock nut. During mounting, ensure careful cleaning of the surfaces and apply the appropriate lubricant to facilitate adjustment. Correct alignment and nut torque are critical to avoid premature failures. If you need assistance, the MR technical team can help you.

As for cross-references, NTN H series adapter sleeves are interchangeable with those of other brands that follow the same dimensional standard, such as SKF, FAG or NSK. However, it is always advisable to verify tolerances and the specific design before replacing a part. Interchangeability is determined by the shaft diameter and the bearing number, not by the brand's part number. If you have doubts, consult us with the original part number and we will indicate the compatible alternative.
