This cylindrical roller bearing carries radial loads while allowing free axial displacement of the shaft in one direction, since the outer ring has two ribs and the inner ring runs smooth (type NU), making it a non-locating bearing. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 43.0 mm, with a net mass of 2.374 kg. Limiting speed reaches 10400 1/min, reference speed 4500 1/min, and the design follows the E series with an M1 cage. The C3 radial internal clearance compensates for thermal expansion and interference fit effects, keeping the bearing suitable for applications with elevated operating temperatures or tight shaft fits. Running accuracy is held to P6, giving tighter dimensional and running tolerances than standard class, which supports smoother rotation at higher speeds. As a single-row separable bearing with cage, it permits mounting and dismounting of the inner and outer rings independently, simplifying installation where axial displacement of the non-locating side is required.
