The adapter sleeve is a component that allows mounting bearings with a tapered bore onto cylindrical shafts. It consists of a tapered sleeve and a lock nut with a lock washer, which secure the bearing position and facilitate mounting and dismounting. It is used in equipment requiring firm and adjustable fastening, such as transmissions, pumps, fans and general machinery. MR Accesorios Industriales sells NTN adapter sleeves in various sizes to suit each application.

The designation of these adapter sleeves combines a series number with the SK suffix and the letter H. For example, 1204SK;H 204 indicates an adapter sleeve for a 1204 series bearing, with SK tapered bore, and the number H 204 identifies the corresponding sleeve and nut. Similarly, 1304SK;H 304, 2204SK;H 304 and 2304SK;H2304 show how the sleeve code relates to the bearing it will mount. Learn more about this nomenclature by consulting MR.

These adapter sleeves are used in a wide variety of industries in Argentina, such as food, chemical, petrochemical and metallurgical. They are present in power transmission equipment, centrifugal pumps, fans, mixers and conveyors. Their design allows mounting bearings on shafts without shoulders or steps, which simplifies machine design and reduces machining costs. They are especially useful when the axial position of the bearing needs to be adjusted or when the shaft does not have a precise tolerance.

To select the right adapter sleeve, take into account the bearing series number and the shaft diameter. The sleeve must match the tapered bore of the bearing and the shaft diameter. During mounting, verify that the surfaces are clean and free of burrs. The nut must be tightened with the lock washer to prevent it from loosening. Lubrication of the sleeve and the bearing is essential for correct operation and longer service life. Follow the manufacturer's recommendations for tightening torque.
