This is a single row cylindrical roller bearing, type NJ, with two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function within the bearing arrangement. The bore diameter is 35.0 mm, outside diameter 72.0 mm, width 17.0 mm, and net mass is 0.295 kg. It uses a TVP2 polymer cage and an E design for increased load rating. Limiting speed is 14100 1/min, reference speed 8100 1/min. Radial internal clearance is C3, allowing for tighter fits or thermal expansion during operation without loss of running accuracy. The one-piece rib configuration permits the inner ring to be axially displaced relative to the outer ring, which supports free axial movement in one direction while providing radial guidance. The bearing is supplied without seals, so lubrication (grease or oil) and sealing must be arranged externally according to the application requirements.
