The RNU210 SKF is a single-row cylindrical roller bearing with cage. This bearing consists of a solid outer ring with cylindrical rollers in a cage. This cage prevents contact between the cylinder rollers, so this bearing type can support higher speeds than full-complement cylinder roller bearings. Also, single-row cylindrical roller bearings with cages are very rigid and they can take high radial forces. Applications of single-row cylindrical roller bearings include gearboxes, agricultural machinery, pumps, compressors, and electric motors.
The RNU210 SKF is a single-row cylindrical bearing with RNU design. RNU bearings are NU bearings without inner rings. The outer ring has two rigid ribs. RNU bearings can only support radial forces and are easy to install. They are suitable for applications with shafts on hardened and polished raceways. The absence of an inner ring allows a larger shaft diameter for stronger, more rigid constructions. In addition, any axial displacement of the shaft relative to the housing is limited only by the width of the raceway on the shaft.
