This single-row cylindrical roller bearing has a bore diameter of 80.0 mm, outside diameter of 170.0 mm, and width of 58.0 mm, with a net mass of 5.863 kg. The design features two ribs on the outer ring and one rib on the inner ring, type NJ, allowing axial displacement of the shaft in one direction while the other bearing on the shaft provides axial location, making it a semi-locating bearing. The polymer cage (TVP2) guides the rollers, and the E design provides an enhanced load rating within the standard envelope dimensions. Limiting speed is rated at 5500 1/min, with a reference speed of 3450 1/min. Radial internal clearance corresponds to CN (Group N), the standard clearance class, suitable for typical fit and temperature conditions without additional preload considerations. The one-directional axial displacement capability of this NJ-type design allows compensation for thermal expansion of the shaft when paired with a locating bearing elsewhere in the arrangement. The cage design supports stable roller guidance at the stated speed ratings, and the bearing is intended for grease or oil lubrication as suited to the operating speed and load conditions defined by the above parameters.
