This single-row cylindrical roller bearing, type NU, has two ribs on the outer ring and a smooth inner ring, which makes it a non-locating bearing allowing free axial displacement between inner and outer ring. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 29.0 mm, and net mass is 1.45 kg. It is built with a polyamide TVP2 cage and E design for increased load capacity, and runs to P6 accuracy. Limiting speed is 8000 1/min, reference speed 5500 1/min, with CN (Group N) radial internal clearance. The non-locating design allows the bearing to accommodate axial shaft expansion without generating additional axial load, while the smooth inner ring raceway permits sliding of the rollers relative to the ring during such movement. The P6 running accuracy suits applications requiring tighter shaft alignment and rotational precision, and the CN clearance corresponds to standard operating conditions without special fit or temperature compensation requirements. The open design without integrated seals requires external sealing and a separate lubrication arrangement suited to the operating speed range.
