The NTN NA series needle roller bearing is a single-row radial bearing with a machined inner ring and steel cage, designed to withstand high radial loads in very small radial spaces. It is used in applications where the ratio between load capacity and cross section is critical, such as gearboxes, pumps, compressors and textile machinery. MR Accesorios Industriales sells the NTN NA series in Buenos Aires, Argentina, and advises you on choosing the correct designation for your application.

The NA series designation is read as follows: NA indicates a needle roller bearing with inner ring, and the number that follows defines the size. For example, in NA498CT the 49 corresponds to the dimension series and CT to the suffix identifying cage or treatment variants. In NA5902CT, the 59 indicates another series of diameters and widths. Suffixes such as CT may indicate modifications to the cage, sealing or internal clearance. To correctly interpret each code, it is best to consult a specialist and send the complete designation.

These bearings are used in industries where space is limited and radial loads are high. In Argentina, they are common in the automotive industry, machine tools, mining equipment, cranes and transmission systems. They also appear in water pumps, air compressors and machinery for the food industry. Their ability to withstand radial loads with a minimal section makes them ideal for applications where other bearings do not fit. MR Accesorios Industriales sells them throughout the country.

To select an NA needle roller bearing, take into account the radial load, rotation speed and available space. Verify that the shaft has the proper hardness and roughness to serve as a raceway if the bearing does not have an inner ring. Lubrication is critical: use grease or oil that withstands the temperature and speed conditions. Mounting must be with an interference fit on the outer ring and controlled radial clearance. Alignment between shaft and housing prevents parasitic axial loads that reduce service life.

NTN NA series needle roller bearings can be interchanged with products from other brands that follow the same standardized dimensions. If you have another brand's code, we can identify the equivalent. Interchangeability depends on tolerances and internal clearance, so it is important to verify the specifications. At MR Accesorios Industriales we help you find the right replacement for your equipment, maintaining original performance.
