INA RNAO series needle roller bearings are radial units with a very low section, designed for shafts where radial space is critical and the load is mainly radial. Their design without an inner ring allows them to be mounted directly on a hardened and ground shaft, which simplifies the assembly and reduces overall size. They are used in machine tools, transmission equipment, pumps and similar applications where rigidity and load capacity in little space make the difference.

The RNAO series designation is read by letters and numbers: the letters identify the design type and the numbers that follow indicate the size. The final number corresponds to the shaft diameter or the nominal raceway dimension, according to the manufacturer's table. To choose the correct part number, have the shaft diameter and available width on hand, and send us the complete part number shown on the drawing or on the original bearing.

These bearings are used in industries in Argentina such as metalworking, food, chemical and mining. They appear in machine tool spindles, conveyor rollers, pumps, compressors, gearboxes and power transmission equipment. Their low profile makes them ideal for replacing bushings or larger-section bearings when weight and space need to be reduced without giving up radial load capacity.

To select correctly, check that the shaft raceway has the proper hardness and roughness, since the bearing does not include an inner ring. Mounting must ensure precise alignment to avoid lateral stresses. Lubrication can be grease or oil depending on the environment, and sealing will depend on the contamination present. If the equipment operates at high temperatures or high speeds, contact us and we will advise you on the most suitable variant.

As for equivalents, needle roller bearings are identified by their designation and standardized dimensions, so different brands offer interchangeable products if the dimensions and tolerances match. It is always advisable to verify the original part number and the operating conditions before replacing. If you have doubts, send us a photo or the engraved part number and we will compare it with the available options.
