The adapter sleeve is a cylindrical component used to secure bearings with a tapered bore onto cylindrical shafts. It is placed between the shaft and the bearing and is tightened using a lock nut or a nut with a lock washer. Its purpose is to ensure a firm, concentric fit, making assembly and disassembly easier without damaging the bearing. MR Accesorios Industriales sells NTN adapter sleeves for a range of industrial applications.

The designation of NTN adapter sleeves is read starting with the letter H followed by numbers that indicate the series type and the shaft diameter. For example, the H30 series is used on bearings with a tapered bore and is identified by codes such as H3026, H3068, H3072, H3076 or H3080. The H31 series, with examples such as H31/500, is used on larger bearings. The H23 series, such as H2326, corresponds to adapter sleeves for bearings with a tapered bore and specific dimensions. The suffixes and final numbers indicate the diameter and thread pitch.

These adapter sleeves are used across a wide range of industries in Argentina, such as metallurgy, cement, mining, food processing and petrochemicals. They are common in equipment with bearings mounted on cylindrical shafts, such as conveyor belts, mills, pumps, fans and gearboxes. They allow bearings with a tapered bore to be fitted onto shafts that have not been machined with a taper, which simplifies machine design and maintenance.

To select the correct adapter sleeve, take into account the shaft diameter, the bearing type and the locking method. Check that the thread matches the lock nut or the nut and lock washer. During assembly, make sure the surfaces are clean and free of burrs. Apply the recommended lubricant and tighten the nut with the appropriate tool, respecting the bearing internal clearance. Correct alignment prevents stress and extends the service life of the assembly.

As for equivalences, adapter sleeves are identified by international standards and can be interchanged between different manufacturers if the dimensions and thread match. It is essential to compare the full part number and the measurements to ensure compatibility. If you have any doubts, ask us with the part number of the original part or the shaft and bearing measurements.
