This single row cylindrical roller bearing has two ribs on the outer ring and one rib on the inner ring, with a loose rib washer fitted internally, corresponding to design type NUP. The design allows axial displacement in one direction while the opposite direction is fixed, making it suitable as a locating bearing. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 29.0 mm, net mass 1.7 kg. Limiting speed is rated at 10400 1/min, reference speed at 5500 1/min. The bearing is fitted with an M1 cage and features the E design, providing increased roller complement and load carrying capacity within the same envelope dimensions. Radial internal clearance corresponds to CN (Group N), suitable for standard fit and load conditions without special clearance requirements. The construction supports high radial loads combined with defined axial guidance in one direction, and the open design requires separate sealing and lubrication arrangements at the point of installation.
