This cylindrical roller bearing carries rolling elements guided by a cage, single row, with two ribs on the outer ring and one rib on the inner ring, type NJ, functioning as a semi-locating bearing. Bore diameter is 150.0 mm, outside diameter 320.0 mm, width 108.0 mm, and net mass 43.02 kg. Limiting speed is rated at 3650.0 1/min, with a reference speed of 1460.0 1/min, and the design corresponds to the E series. The rib arrangement allows axial displacement in one direction while the opposite side of the assembly is fixed, which lets the bearing accommodate thermal expansion of the shaft without introducing axial preload. The C3 internal clearance provides additional room to compensate for temperature rise during operation, and the reinforced E design increases load carrying capacity relative to standard internal geometry. The MCA cage guides the rollers securely at the stated speed range, making the bearing suitable for radial loads combined with limited axial guidance on one side of the shaft.
