INA NA-XL series needle roller bearings are radial bearings with high load capacity in a very compact cross-section design. They are used when radial space is limited and high loads must be supported with a compact assembly. MR Accesorios Industriales supplies this INA line, an official brand that MR distributes, with technical advice to select the correct part number for your application.

The designation of these bearings combines letters and numbers that indicate the type and dimensions. The NA series corresponds to needle roller bearings with an inner ring; the number that follows, as in NA49/22-XL or NA69/28-XL, refers to the bore diameter according to an internal code. The XL suffix identifies the current INA design. In the examples NA4822-XL and NA4826-XL, the larger number indicates a different outside diameter within the same family. Knowing these codes helps you order the exact replacement.

These bearings are used in machine tools, pumps, compressors, electric motors, transmission equipment and roller systems in production plants. In Argentina, they are common in the automotive, metalworking, food and packaging industries, where mounting spaces are tight and radial loads are high. They are also found in lifting and continuous conveying equipment, where reliability and service life are critical.

To select the right bearing, take into account the radial load, rotation speed and available space. Verify that the shaft and housing have the appropriate hardness and surface finish. The assembly must ensure precise alignment to avoid lateral forces. Lubrication can be grease or oil depending on the operating conditions; in contaminated applications, consider additional seals or protection. A properly fitted assembly extends bearing life.

INA needle roller bearings can be interchanged with those from other brands that follow the same dimensional designation, such as SKF, FAG or NTN, as long as tolerances and design type are respected. It is important to verify the suffix and critical dimensions before replacing. At MR Accesorios Industriales we can guide you on the appropriate equivalent for your equipment, without compromising performance.
