This cylindrical roller bearing carries pure radial load and allows free axial displacement of the shaft relative to the housing, functioning as a non-locating bearing. It is a single row NU type with two ribs on the outer ring and a smooth inner ring, bore diameter 80.0 mm, outside diameter 125.0 mm, width 22.0 mm, net mass 0.96 kg. Limiting speed is rated at 10800 1/min, reference speed at 5000 1/min, with a brass cage M1 and running accuracy in class P6. The internal clearance C3 compensates for thermal expansion during operation and permits a tighter fit than standard clearance without risk of overloading the rollers. The smooth inner ring combined with the two-rib outer ring allows axial displacement between the rings, making this design suitable for the floating bearing position on a shaft where axial fixation is provided elsewhere. The P6 accuracy class supports applications requiring tighter running tolerances than standard class bearings.
