The NTN RNA49 series needle roller bearing is a radial bearing without an inner ring, designed to withstand high radial loads in very tight radial spaces. It is used in applications where the shaft acts directly as the raceway, which allows for a more compact and lighter design. It is a common solution in transmissions, pumps, compressors and industrial machinery that requires high load capacity within a limited outside diameter.

The RNA49 series designation is interpreted as follows: the letters RNA indicate a needle roller bearing without an inner ring, with a steel cage and a machined outer ring. The number that follows, as in RNA495T2, indicates the size and the dimension series. The suffix T2 identifies a specific design variant within the family. Knowing this nomenclature allows you to quickly identify the product and request the exact part number you need.

These bearings are used in industries such as automotive, metallurgical, food processing and machine tool. In Argentina, they are common in gearboxes, water pumps, air compressors and material handling equipment. Their ability to withstand radial loads in confined spaces makes them ideal for applications where the shaft diameter is limited and rigidity and precision are required.

To correctly select an RNA49 needle roller bearing, take into account the hardness and roughness of the shaft raceway, which must meet the requirements for direct rolling. Check the alignment between the shaft and the housing, since these bearings are sensitive to misalignment. Proper lubrication, with grease or oil depending on the speed and working temperature, extends service life. Sealing of the assembly is also key to prevent particle contamination.

Regarding equivalents, needle roller bearings without an inner ring from different brands can be interchanged if the main dimensions and load conditions match. Always verify the complete part number and tolerances. If you have another brand's part number or an unidentified part, at MR Accesorios Industriales we can tell you the compatible alternative or quote the exact size you need.
