This cylindrical roller bearing is a single-row locating bearing with a rib arrangement of 2 ribs on the outer ring and 1 rib on the inner ring, plus an internal rib washer, corresponding to design NUP. Bore diameter is 50.0 mm, outside diameter 90.0 mm, width 20.0 mm, and net mass is 0.463 kg. The cage is a glass-fibre reinforced polyamide cage, type TVP2, and the bearing features the reinforced E design for increased load carrying capacity. Limiting speed is 11100 1/min, reference speed 6600 1/min. Radial internal clearance corresponds to CN (Group N), suitable for standard fit conditions without additional preload requirements. The rib configuration allows the bearing to carry axial loads in one direction while acting as a locating bearing on the shaft, fixing its position. The polyamide cage design supports smooth roller guidance at the given speed range, and the separable inner ring construction simplifies mounting and dismounting during service.
