This cylindrical roller bearing is a single-row non-locating design with a smooth inner ring (0 ribs) and 2 ribs on the outer ring, type NU, allowing free axial displacement between inner and outer ring within the bearing. Bore diameter is 120.0 mm, outside diameter 260.0 mm, width 55.0 mm, and net mass 15.8 kg. The bearing carries an M1 cage and is manufactured to running accuracy class P6, with limiting speed of 4550.0 1/min and reference speed of 2650.0 1/min. Radial internal clearance falls in group C3, giving additional play suited to compensate thermal expansion during operation. The non-locating configuration permits axial shaft movement while maintaining radial support, making this bearing suitable for mounting positions where the shaft requires freedom of axial displacement. The P6 accuracy class supports applications demanding tighter running tolerances than standard class, and the E design provides increased load carrying capacity within the given envelope dimensions.
