The SKF needle roller bearing of the NA RSX series is a radial needle roller bearing with an inner ring and seal. It is used to withstand radial loads in tight spaces, where a ball bearing does not fit. Its needle design allows high load capacity with a minimal cross-section. It is a common solution in machine tools, transmission equipment and applications where axial and radial space is limited. MR Accesorios Industriales carries this SKF line and advises you on choosing the right part number.

The NA RSX series designation is read as follows: NA indicates that it is a needle roller bearing with an inner ring, unlike the series without an inner ring that are mounted directly on the shaft. The RSX suffix indicates that the bearing comes sealed from the factory, with a seal that retains lubricant and blocks the ingress of contaminants. A specific example of this series is NA 22/8.2RSX, where the numbers define the main dimensions. Knowing this logic allows you to identify variants and order the exact part number.

This type of bearing is used in industries where space is critical: machine tools, power transmission equipment, pumps, compressors, conveyor belts and agricultural machinery. In Argentina, it is common to find it in the maintenance of continuous production equipment, where reducing downtime is the goal. Its ability to withstand high radial loads with a low profile makes it ideal for gearboxes, pulleys and rollers. It is also used in oscillating or slow-rotation applications with high load.

To select the right bearing, take into account the shaft diameter, the outer diameter and the width your application requires. The RSX seal is already built in, which simplifies mounting and reduces maintenance. Verify that the shaft and housing have adequate hardness and roughness, and that alignment is correct to avoid parasitic axial loads. Factory lubrication is sufficient for most cases, but under severe conditions it may require relubrication. Follow the manufacturer's recommendations for mounting.

As for equivalents, needle roller bearings with an inner ring and seal from different brands can be interchanged if the dimensions and seal type match. Do not rely on the part number alone: compare inner diameter, outer diameter and width. SKF is a global benchmark, and MR Accesorios Industriales carries it as an official brand. If you need to replace a bearing from another brand, send us the measurements and we will help you find the right SKF equivalent.
