This single row cylindrical roller bearing, symbol NJ311-E-XL-TVP2-C3, has a bore diameter of 55.0 mm, an outside diameter of 120.0 mm and a width of 29.0 mm, with a net mass of 1.48 kg. The outer ring carries two ribs and the inner ring one rib, giving the NJ design a semi-locating function that allows axial displacement in one direction while providing guidance in the other. The bearing uses a TVP2 cage and is built to the reinforced E design, with a limiting speed of 8000 1/min and a reference speed of 5500 1/min. The semi-locating configuration lets this bearing accommodate axial displacement between shaft and housing, which is useful where thermal expansion or manufacturing tolerances need to be compensated on one side while the other bearing position provides axial fixation. Radial internal clearance is C3, wider than normal, compensating for interference fits and operating temperature rise. The TVP2 cage is a polymer cage suited to the speeds indicated, and the bearing is intended for grease or oil lubrication as a separate mounted component without integrated sealing.
