The INA needle roller bearing of the NKI series with TV and XL suffixes is a radial bearing with high load capacity in a very small space. It is used when the design calls for a small outside diameter and a limited width, but radial loads are demanding. MR Accesorios Industriales supplies this INA line, an official brand that MR carries, with technical advice to choose the right size.

The NKI series designation is read in blocks: the letters NKI identify a needle roller bearing with machined inner and outer rings, suitable for high radial loads. The first number after the letters indicates the bore diameter and the second, separated by a slash, the overall width. The TV and XL suffixes appear in examples such as NKI5/12-TV-XL, NKI6/16-TV-XL or NKI25/20-TV-XL: TV indicates the polyamide cage and XL the higher load capacity execution of the current generation. Send the complete part number to identify the exact variant.

These bearings are used in Argentine industries where radial space is critical: machine tools, pumps, compressors, gearboxes, power transmission equipment and lifting mechanisms. They also appear in conveyor rollers, textile machines, packaging equipment and linear guide systems. In food and beverage, paper, petrochemical and automotive plants they are chosen for their rigidity and their ability to withstand radial loads with a slim mounting profile.

To select the right bearing, take into account the shaft diameter, the available width and the expected radial load. The NKI series supports grease or oil lubrication; in contaminated applications, consider seals or external protection. Mounting is done with an interference fit on the shaft and in the housing according to the load type, taking care with alignment so as not to load the edges of the needles. The TV cage and the XL execution influence the limiting speed and the load capacity: check the data sheet for each size.

As for equivalents, needle roller bearings are identified by their standardized designation, but each manufacturer may use its own suffixes for cage, tolerance or execution. When looking for a replacement, compare bore diameter, outside diameter, width and load capacity, not just the part number. MR Accesorios Industriales can advise you on interchangeability within the INA line and with other equivalent brands, without compromising the performance of the assembly.
