This single row cylindrical roller bearing carries radial loads through a configuration with two ribs on the outer ring and one rib on the inner ring, giving it the semi-locating function typical of type NJ construction. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 43.0 mm, and net mass 2.46 kg. The limiting speed is rated at 10400 1/min, with a reference speed of 4500 1/min. Design E denotes an optimized internal geometry for increased load rating. The bearing is fitted with an M1 solid brass cage, suited for higher speed operation and stable roller guidance. Radial internal clearance falls into C3 (Group 3), compensating for tighter fits or thermal expansion during operation. Due to the one rib on the inner ring and two ribs on the outer ring, the bearing allows limited axial displacement of the shaft in one direction, making it suitable as a semi-locating position in a shaft arrangement where controlled axial guidance combined with radial load capacity is required.
