This cylindrical roller bearing carries radial loads while allowing free axial displacement between shaft and housing, functioning as a non-locating bearing. It is a single row design of type NU, with two ribs on the outer ring and a smooth (rib-free) inner ring, bore diameter 45.0 mm, outside diameter 85.0 mm, width 23.0 mm, mass 0.516 kg. Limiting speed is 11800 1/min, reference speed 5800 1/min. The bearing uses a polyamide cage (TVP2) and the reinforced E design for increased load rating. Radial internal clearance is C3, suited for applications where thermal expansion or interference fits require additional clearance beyond normal. Running accuracy is manufactured to P6 tolerance class, allowing tighter shaft positioning than standard P0. The open design without integrated sealing requires external sealing and separate lubrication, either grease or oil, matched to the operating speed range.
