The NSK IR series inner ring is a precision component used as the inner raceway in needle roller bearings. It is mounted on the shaft and provides a hard, ground surface for the rollers, enabling compact arrangements with high load capacity. It is a key part when the shaft does not have the hardness or finish suitable to act directly as a raceway. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and advises you on choosing the correct part number for your application.

The IR series designation is read as the letters IR followed by a number indicating the bore diameter and width, and it may carry the suffix -1 when it corresponds to a variant with modified dimensions. For example, IR-68 identifies a ring with a specific bore diameter and width, while IR-68-1 is the version with a different width. Likewise, other part numbers in the series cover different combinations of diameter and width. Find out the exact part number you need and we'll quote it for you.

These rings are used in needle roller bearings and roller assemblies that require a removable inner raceway. They are common in applications where radial space is limited and high load capacity is needed, such as gearboxes, pumps, compressors, machine tools and mining equipment. In Argentina, they are found in the automotive sector, the metalworking industry and agricultural machinery manufacturing, among others. MR Accesorios Industriales sells them to supply both repair shops and production lines.

To select the right inner ring, take into account the shaft diameter, the bearing width and the type of load. The IR series is manufactured with controlled tolerances and ground surfaces to ensure a correct fit and long service life. It is essential to verify alignment between the ring and the shaft, as well as proper lubrication, to avoid premature wear. If the shaft is worn, the inner ring allows functionality to be restored without replacing the entire shaft.

NSK IR series inner rings can be interchanged with those of other brands that follow the same dimensional designation, although it is always advisable to confirm tolerances and surface treatment. Equivalent parts from different manufacturers exist on the market, but dimensions and quality can vary.
