The INA support rollers of the RNA RSR series are single row cylindrical roller bearings with thick-walled outer ring and without inner ring, mounted directly on a hardened shaft or pin. They are used as cam or support rollers in guiding, cam and transport systems, where the load is radial and the movement is alternating or continuous. Their compact design and RSR sealing make them suitable for environments with dust or moderate moisture.

The designation of these rollers is read in parts. The letters RNA indicate that the bearing has no inner ring: the raceway is formed directly on the shaft. The number that follows — as in RNA22/6-2RSR or RNA2205-2RSR — identifies the size and dimension series. The suffix 2RSR indicates lip seals on both sides, which retain lubrication and block the entry of contaminants. In the series examples, this combination is repeated: RNA with number and 2RSR ending.

These rollers are used in actuating cams, linear guides, roller conveyors, packaging machines, printing equipment and reciprocating motion systems. In Argentine industry they appear in food production lines, bottling plants, machine tools and lifting equipment. Their function is to support radial loads on a shaft, with the possibility of rotating on an outer raceway that acts as a support or cam roller depending on the mounting.

To select the correct roller, take into account the diameter and hardness of the shaft or pin: the inner raceway is formed on that surface, so it must be ground and have adequate hardness. The 2RSR seal is convenient in environments with dust, chips or moisture. Factory lubrication can be supplemented according to the operating conditions. Check shaft alignment and avoid axial loads, because the roller is designed for radial forces.

INA support rollers can be interchanged with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG or NTN, as long as the outer diameter, width and shaft diameter match. The RNA designation with 2RSR suffix is common to several manufacturers, but it is advisable to confirm the equivalence by code before replacing. MR Accesorios Industriales supplies INA as an official brand and can guide you on interchangeability.

If you need an INA support or cam roller of the RNA RSR series, send the complete code — for example RNA2205-2RSR — by WhatsApp and we will quote you promptly. MR Accesorios Industriales has more than 80 years in the business and can advise you on the application, mounting and available alternatives for your equipment.
