The NSK HR series tapered roller bearing is a separable bearing that supports radial and axial loads in one direction. Its design with tapered raceways and guided rollers allows linear contact that distributes the load better. It is used in applications where motion must be transmitted with high demand, such as gearboxes, machine tool spindles and conveying equipment. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you to choose the correct designation.

The designation of the HR series is read in blocks: the letters HR identify the NSK line of tapered roller bearings; the numbers that follow, as in HR 302/22, HR 303/28 or HR 322/32, indicate the size and internal design. The suffix after the slash corresponds to the bore diameter in millimeters. The 302, 303 and 322 series share the same operating principle, but differ in the ratio between width and diameter. When requesting a quote, provide the complete code so we can give you the exact reference.

These bearings are used in Argentine industries such as food, metallurgy, mining and agriculture. They are present in speed reducers, conveyor belts, mills, mixers, pumps and road equipment. They are also found in the automotive and railway sectors, where combined loads and shocks are frequent. Their ability to work with moderate misalignment makes them suitable for transmission shafts and support rollers. MR Accesorios Industriales sells them for replacement and new projects.

To select the correct bearing, take into account the radial and axial load, the rotation speed and the available space. Mounting requires proper alignment of the raceways and adjustment of axial clearance according to the type of application: in general, a clearance close to zero is sought to avoid vibrations. Lubrication can be with grease or oil, and sealing will depend on the environment: if there is dust or moisture, it is advisable to choose variants with seals. The HR series allows mounting in pairs for loads in both directions.

Regarding equivalences, tapered roller bearings are interchangeable between brands if the main dimensions and raceway angle match. The NSK HR series has correspondence with lines from other manufacturers, but each manufacturer may vary tolerances and suffixes. If you bring the code of another brand or an unidentified part, at MR we indicate the compatible alternative. We work with the designation shown on the drawing or on the original part.
