The NSK HR series tapered roller bearing is a separable unit designed to handle radial and axial loads in a single direction. Its tapered raceways and guided rollers create linear contact that distributes load effectively. Typical uses include gearboxes, machine tool spindles and conveying equipment, where motion must be transmitted under demanding conditions. MR Industrial Accessories supplies this line and helps you select the right designation.

The part number breaks down into sections: the HR prefix denotes NSK's tapered roller bearing line; the following digits, as in HR 302/22, HR 303/28 or HR 322/32, specify size and internal design. The number after the slash gives the bore diameter in millimeters. The 302, 303 and 322 series operate on the same principle but vary in the ratio of width to diameter. When requesting a quote, always provide the complete code so we can identify the exact reference.

These bearings appear in industries such as food processing, metallurgy, mining and agriculture. They are found in speed reducers, conveyor belts, mills, mixers, pumps and road equipment, as well as in automotive and railway applications where combined loads and shocks are common. Their ability to accommodate moderate misalignment suits them to transmission shafts and support rollers. MR Industrial Accessories supplies them for both replacement and new projects.

Selection depends on radial and axial load, rotation speed and available space. During mounting, align the raceways and set axial clearance according to the application; generally, a clearance near zero is desired to minimize vibration. Lubrication can be grease or oil, and sealing depends on the environment: in dusty or moist conditions, choose variants with seals. The HR series can be mounted in pairs to handle loads in both directions.

Interchangeability between brands is possible when principal dimensions and raceway angle match. The NSK HR series has equivalents in other manufacturers' lines, but tolerances and suffixes may differ. If you provide a competitor's code or an unidentified part, we can suggest a compatible alternative. We work from the designation on your drawing or original part.
