This single row cylindrical roller bearing, type NJ, has a bore diameter of 55.0 mm, outside diameter of 120.0 mm and width of 29.0 mm, with a net mass of 1.48 kg. The outer ring has 2 ribs and the inner ring has 1 rib, giving the bearing its semi-locating function that allows axial displacement in one direction while providing axial guidance in the other. Design E denotes the reinforced internal geometry with increased roller load rating, and the bearing runs on a TVP2 cage. Limiting speed is 8000.0 1/min, reference speed 5500.0 1/min. The semi-locating design allows the bearing to accommodate axial expansion of the shaft while still providing guidance in one axial direction, making it suitable for use as one of two bearings supporting a shaft where the other bearing takes up the remaining axial freedom. Radial internal clearance falls in group CN (normal), suitable for standard fit and temperature conditions without additional clearance adjustment. The TVP2 cage, made of glass-fibre reinforced polyamide, guides the rollers with low friction and supports the stated speed ratings; the bearing is supplied without seals or integrated lubrication, requiring lubricant selection and relubrication intervals to be defined separately.
