This cylindrical roller bearing carries a bore diameter of 45.0 mm and an outside diameter of 100.0 mm, with a net mass of 1.389 kg. It is built as a double row cylindrical roller bearing with a particularly thick-walled outer ring and a full complement cylindrical roller set running against an inner ring; the outer ring is guided axially by the rolling elements themselves, and sealing is provided on both sides by labyrinth seals (2LB). Because axial guidance comes directly from the roller set rather than a separate flange arrangement, the outer ring runs true under radial load while the double row layout adds load-carrying capacity across the full roller length. The labyrinth seals on both faces keep contaminants out of the raceway without adding contact friction, which supports continuous operation where the roller surface itself acts as the running track.
