Carries pure radial loads and axially locates the shaft in one direction, thanks to the two ribs on the outer ring and single rib on the inner ring characteristic of the NJ design. The single-row cylindrical roller set with polyamide TVP2 cage and E design allows the bore of 25.0 mm, outside diameter of 52.0 mm and width of 18.0 mm to carry a limiting speed of 19800 1/min and a reference speed of 9600 1/min, with a net mass of 0.164 kg. The inner ring can be displaced axially relative to the outer ring, since the rollers are only guided by the ribs on one side, making this bearing suitable as a non-locating support where free axial movement must be accommodated while radial guidance is maintained. Radial internal clearance is CN (Group N), giving standard running clearance without additional preload, and the cage design supports operation up to the stated limiting speed without external reinforcement.
