The NSK RNA TT series needle roller bearing is a radial bearing without an inner ring, designed to withstand high radial loads with a reduced section profile. It is used when radial space is limited and the shaft acts directly as the raceway. Its needle and cage construction allows high speeds and a large load capacity relative to its size. MR Accesorios Industriales sells this line for industrial applications in Buenos Aires, Argentina.

The RNA TT series designation is interpreted as follows: the letters RNA indicate a needle roller bearing without an inner ring, with a machined outer ring. The number that follows, as in RNA49/28TT or RNA69/32TT, corresponds to the shaft diameter or a size code depending on the series. The TT suffix indicates a configuration with two ribs or seals, depending on the version. The examples RNA49/28TT, RNA49/32TT, RNA49/38TT, RNA49/42TT, RNA49/48TT, RNA69/22TT, RNA69/28TT and RNA69/32TT show the variety of sizes available within this family.

These bearings are used in industries such as automotive, machine tools, transmission equipment, pumps, compressors and packaging machinery, among others. In Argentina, they are common in the repair of gearboxes, electric motors, lifting systems and agricultural equipment. Their ability to withstand radial loads in tight spaces makes them suitable for applications where the outer diameter is limited and high rigidity is required.

To select the correct bearing, take into account the shaft diameter, the radial load and the lubrication conditions. The RNA TT series can be lubricated with grease or oil, and it is important to ensure precise alignment between the shaft and the housing. The sealing or protective plates, when applicable, help retain the lubricant and prevent contamination. Assembly must be carried out with suitable tools so as not to damage the needles or the cage.

As for equivalences, needle roller bearings without an inner ring from different brands can be interchanged if the main dimensions and load capacity match. It is essential to verify the complete code and the tolerances. If you have the code from another brand or an unidentified part, at MR Accesorios Industriales we can indicate the compatible alternative or quote the exact code you need.
