The NTN RNA series needle roller bearing is a component with high radial load capacity and minimal cross-sectional space. It is used in applications where the shaft cannot be machined with an inner raceway, since the needle rolls directly on the journal. Its compact design reduces the size of the assembly and handles high loads. MR Accesorios Industriales sells this series with the backing of more than 80 years in the Argentine industrial market.

The RNA series designation is read as follows: the letters RNA indicate a needle roller bearing without an inner ring, and the numbers that follow define the outer diameter and the width. For example, RNA498CT and RNA5902CT belong to the RNA49 and RNA59 series respectively. The CT suffix indicates a stamped steel cage, which guides the needles and allows high speeds. Knowing these part numbers makes correct selection easier.

These bearings are used in industries such as automotive, machine tools, power transmission equipment, pumps, compressors and agricultural machinery. In Argentina, they are common in gearboxes, camshafts, conveyor rollers and lifting systems. Their ability to handle high radial loads in tight spaces makes them ideal for applications where the shaft diameter is limited and rigidity is required.

To select an RNA bearing, take into account the hardness and roughness of the shaft raceway, which acts as the inner ring. Lubrication must be adequate: oil or high-viscosity grease depending on speed and temperature. Mounting requires precise alignment and extreme cleanliness to avoid contamination. Check the internal clearance and sealing; although this series does not include seals, you can complement it with external radial shaft seals. Incorrect mounting shortens service life.

As for equivalents, needle roller bearings without an inner ring are identified by international standards that define dimensions and tolerances. Other brands offer similar series, but it is essential to compare not only the part number but also the load capacity and the cage type. When replacing, check the shaft and housing dimensions. If you have doubts, the MR technical team can advise you.
