This single-row cylindrical roller bearing carries a bore of 50.0 mm, outside diameter of 110.0 mm and width of 27.0 mm, with a net mass of 1.147 kg. The outer ring has two ribs and the inner ring has one rib, giving the NJ design its semi-locating function that allows axial displacement in one direction while guiding the shaft in the other. It runs with a polyamide cage (TVP2), reinforced E design for higher load capacity, and normal radial internal clearance (CN, Group N). Limiting speed is rated at 8900 1/min, reference speed at 6000 1/min. The semi-locating layout makes this bearing suitable for supporting a shaft where axial fixation is needed on one side while allowing thermal expansion on the other. The E design increases the number and size of rolling elements for higher radial load capacity within the same envelope dimensions. Standard CN clearance and the TVP2 cage support operation at the stated reference and limiting speeds without special lubrication requirements beyond normal grease or oil lubrication practice for this bearing class.
