INA RNA RSR series yoke rollers are single-row cylindrical roller bearings with a thick-walled outer ring and no inner ring, mounted directly on a hardened shaft or pin. They are used as cam followers or yoke rollers in guiding, cam and conveying systems, where the load is radial and the motion is reciprocating or continuous. Their compact design and RSR sealing make them suitable for environments with dust or moderate humidity.

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 the dimension series. The suffix 2RSR indicates lip seals on both sides, which retain lubrication and block the entry of contaminants. In the examples of the series, that combination is repeated: RNA with a number and the 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 carry radial loads on a shaft, with the possibility of rotating on an outer raceway that acts as a yoke roller or cam follower 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 sealing is convenient in environments with dust, chips or humidity. Factory lubrication can be supplemented according to the operating conditions. Verify shaft alignment and avoid axial loads, because the roller is designed for radial forces.

INA yoke 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 the 2RSR suffix is common to several manufacturers, but it is advisable to confirm the equivalence by part number before replacing. MR Accesorios Industriales sells INA and can advise you on interchangeability.
