This cylindrical roller bearing carries the design NU, with two ribs on the outer ring and a smooth inner ring, allowing axial displacement between the rings and making it a non-locating bearing. Bore diameter is 65.0 mm, outside diameter 140.0 mm, width 48.0 mm, and net mass is 3.58 kg. The bearing is fitted with an M1 cage and built to the E design. Limiting speed is 8800 1/min, reference speed 4000 1/min, and running accuracy corresponds to class P6. Radial internal clearance falls within CN (Group N), suitable where standard clearance is required without additional axial preload. The non-locating construction allows the bearing to accommodate axial displacement of the shaft relative to the housing, which is useful where thermal expansion or shaft length changes must be compensated. The P6 accuracy class supports applications requiring tighter running tolerances than standard class, while the smooth inner ring design permits smooth axial sliding of the rollers against the inner raceway.
