The NTN NA series needle roller bearing is a single-row radial bearing with a steel cage and machined inner ring. Its compact design allows it to withstand high radial loads in spaces where a ball bearing will not fit. It is used in machine tools, gearboxes, pumps, transmission equipment and industrial applications that require high load capacity with a minimal section. MR Accesorios Industriales sells these products with technical advice so you can choose the correct size.

The NA series designation reads as follows: NA indicates a needle roller bearing with an inner ring; the following numbers define the bore diameter and the dimension series. For example, NA49/22R has a 22 mm bore and belongs to the 49 series; NA69/28R also has a 28 mm bore but belongs to the 69 series, with a larger section. The suffix R indicates a riveted steel cage, suitable for high speeds and moderate temperatures.

In Argentine industry, these bearings are found in machine tool spindles, gearbox and transmission shafts, water and oil pumps, compressors, packaging equipment and automotive production lines. Their ability to withstand radial loads with little radial space makes them ideal for mechanisms where the outer diameter is limited. MR Accesorios Industriales supplies them to workshops, factories and industrial maintenance operations throughout the country.

To select the correct bearing, take into account the bore diameter, the required load capacity and the lubrication conditions. The NA series accepts grease or oil lubrication; in applications with contamination, consider additional seals. Mounting must be done with suitable tools, avoiding direct blows to the cage. Check the alignment of the shaft and the housing to avoid parasitic axial loads that reduce service life.

NTN NA series needle roller bearings are interchangeable with those of other brands that follow the same dimensional nomenclature. If you have another brand's part number, we can identify the equivalent. We can also quote the exact size based on the shaft and housing dimensions. Standard interchangeability makes replacement easy without modifying the equipment design.
