The NTN NK series needle roller bearing is a single-row radial bearing, without an inner ring, designed to withstand high radial loads with a very low section profile. It is used when axial and radial space is limited and the shaft acts directly as a raceway. It is a common solution in transmissions, pumps, compressors and continuous production machinery. MR Accesorios Industriales sells it in Buenos Aires, Argentina.

The NK series designation is read as NK followed by two numbers separated by a slash: the first indicates the bore or raceway diameter and the second the overall width. For example, NK12/16 corresponds to a needle roller bearing with 12 mm bore diameter and 16 mm width. The NK series has no inner ring, so the shaft must meet the right hardness and roughness to work as a raceway. The usual suffixes in this family indicate sealing, internal clearance or special tolerance variants, and are interpreted according to the current NTN catalogue.

In Argentine industry, NK needle roller bearings are used in gearboxes, hydraulic pumps, air compressors, machine tools, packaging equipment and transmission lines. They also appear in automotive applications, such as gearboxes and steering systems, and in agricultural machinery. Their radial load capacity in a minimal space makes them suitable for assemblies where the outer diameter cannot be increased. MR Accesorios Industriales supplies them to workshops, plants and equipment manufacturers throughout the country.

To correctly select an NK bearing, take into account the radial load, the rotation speed and the environmental conditions. If the shaft does not reach the required hardness, it can be combined with a suitable inner ring. Assembly requires precise alignment and adequate lubrication: grease for general applications or oil in systems with circulation. The side seal protects against contaminants and lubricant loss. Check the internal clearance and the shaft tolerance before installing, and avoid impacts that could damage the needles or the cage.

NTN NK needle roller bearings can be interchanged with those of other brands that follow the same dimensional designation, such as SKF, FAG, NSK or INA, as long as the bore diameter, outer diameter and width match. Differences may appear in the cage, the sealing or the tolerance, so it is advisable to verify the application. If you have the part number from another brand, at MR Accesorios Industriales we will tell you the compatible equivalent and quote the exact part you need.
