The INA RNA RSR line covers single-row cylindrical roller bearings that run without an inner ring. The outer ring is thick-walled, so the roller sits straight on a hardened pin or shaft and the raceway is formed on that surface. Typical duty is radial: cam actuation, guidance and conveying, with either back-and-forth or steady rotation. The RSR seal keeps grease in place and helps where dust or moderate humidity is present.

Reading the code is the quickest way to know what you are holding. RNA means there is no inner ring, so the shaft itself becomes the inner raceway. The figure in the middle, as in RNA22/6-2RSR or RNA2205-2RSR, sets the size and the dimension series. The 2RSR ending tells you the roller carries lip seals on both sides. That same pattern runs through the whole series: RNA, a size number, then the sealing suffix.

You will find these rollers on actuating cams, linear guides, roller conveyors, packaging machinery, printing units and other reciprocating mechanisms. Food production lines, bottling plants, machine tools and lifting equipment also use them. Mounted one way they act as a cam follower; mounted another way they work as a yoke roller. Either way, the job is to take radial load against a shaft.

Selection starts with the pin or shaft. Because the inner raceway is created on that surface, it has to be ground and hard enough for the duty. The 2RSR seals are the right choice when dust, chips or humidity are present. Grease applied at the factory can be supplemented to suit the operating conditions. Check that the shaft is aligned, and keep axial forces off the roller, since it is built for radial load.

INA yoke rollers can be replaced by rollers from other makers that use the same dimensional nomenclature, provided outer diameter, width and shaft diameter line up. SKF, FAG and NTN are examples of brands that follow that system. RNA with the 2RSR suffix appears across several manufacturers, so confirm the equivalence by part number before you swap anything. MR supplies INA and can help you check interchangeability.
