This cylindrical roller bearing carries one row of rollers guided by a polyamide cage (TVP2) between two ribs on the outer ring, while the inner ring runs smooth without ribs, allowing free axial displacement and making it a non-locating bearing. Bore diameter is 50.0 mm, outside diameter 90.0 mm, width 23.0 mm, net mass 0.553 kg. The E design provides increased load carrying capacity, limiting speed reaches 11100 1/min and reference speed is 5300 1/min, with running accuracy to P6. Radial internal clearance is C3 (Group 3), giving extra clearance to compensate for thermal expansion during operation. The smooth inner ring allows axial movement to accommodate shaft expansion or misalignment, making this bearing suitable as a non-locating position in a shaft arrangement. No integrated seals are present, so external sealing and separate lubrication with grease or oil must be provided according to the operating conditions.
