The NTN NK+IR series needle roller bearing is an assembly consisting of an NK type needle roller bearing and an IR inner ring. It is used when radial space is limited and high load capacity is required. The inner ring allows mounting on shafts without special heat treatment. MR Accesorios Industriales sells this series in Buenos Aires, Argentina.

The NK+IR series designation combines two components. The NK code indicates a needle roller bearing without inner ring, with standardized dimensions. The number that follows corresponds to the bearing bore diameter (in millimeters). Then a slash and another number indicate the total width. The letter T2 indicates a design with polyamide cage. The suffix +IR identifies the inner ring supplied with the bearing; its dimensions are expressed as IR inner diameter × outer diameter × width, for example IR5×8×12. Thus, the complete code indicates the bore diameter, the width and the inner ring dimensions.

This series is used in applications where radial space is critical and loads are high. In Argentina, it is common in machine tools, pumps, compressors, electric motors, transmission equipment and agricultural machinery. It also appears in conveyor rollers, cam systems and oscillating mechanisms. The combination with inner ring facilitates mounting on shafts that are not hardened or ground, which simplifies design and reduces costs. It is a common solution in equipment where high rigidity and rotational precision are required.

To select correctly, take into account the radial load and the operating speed. The IR inner ring must have the inner diameter suitable for the shaft and the width matching that of the bearing. Check the lubrication: these units accept grease or oil, and in high-speed applications oil with circulation is recommended. Sealing will depend on the environment: if there is dust or moisture, consider external seals or bearings with seals. Alignment between shaft and housing is essential to avoid parasitic axial loads. Follow the manufacturer's mounting instructions to ensure service life.

Regarding equivalents, needle roller bearings with inner ring from other brands can be interchanged if the main dimensions match: bore diameter, outer diameter and width. The NTN NK+IR series is standard and usually has equivalents in other manufacturers' catalogs. Always check tolerances and cage type, as they may vary. If you need to replace an existing bearing, the safest is to compare the dimensions and load conditions. MR Accesorios Industriales can advise you on selecting the right alternative.
