This cylindrical roller bearing accommodates axial displacement of the shaft in one direction, acting as a non-locating bearing within a bearing arrangement. It is a single row design of type NU, with two ribs on the outer ring and a smooth inner ring, allowing free axial movement between the rings. Bore diameter is 40.0 mm, outside diameter 80.0 mm, and width 18.0 mm, with a net mass of 0.365 kg. The limiting speed is 12500 1/min, with a reference speed of 7500 1/min. The bearing features a polyamide cage (TVP2) and the reinforced E design, offering increased load capacity within the same envelope dimensions. Radial internal clearance corresponds to C3 (Group 3), providing additional clearance to compensate for thermal expansion during operation. Running accuracy is manufactured to P6 tolerance class, suitable for applications requiring precise shaft guidance and axial freedom under radial load.
