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 does not fit. It is used in machine tools, gear reducers, pumps, transmission equipment and industrial applications that require high load capacity with a minimal section. MR Accesorios Industriales sells the complete line with technical advice so you can choose the right 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 series 49; NA69/28R also has a 28 mm bore but belongs to series 69, with a larger section. The R suffix indicates a riveted steel cage, suitable for high speeds and moderate temperatures.

In Argentine industry these bearings are found in machine tool spindles, gear reducer shafts and transmission boxes, 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 on the cage. Check the alignment of the shaft and housing to avoid parasitic axial loads that reduce service life.

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