This cylindrical roller bearing carries a full complement of double-row cylindrical rollers set within a particularly thick-walled outer ring, giving it high load-carrying capacity relative to its size. The outer ring is guided axially by the rolling elements themselves, and the design includes a solid roller stud with a fixing thread, a mounting aid, and an eccentric collar. Outside diameter is 52.0 mm, width is 66.0 mm, and net mass is 0.487 kg. Sealing is provided on both sides by labyrinth seals (2LB), protecting the rolling elements from contamination while allowing the outer ring to rotate against a track surface. The stud design with fixing thread and eccentric collar allows the roller to be mounted directly onto a shaft end and adjusted for position, while the thick-walled outer ring and full complement roller set support the radial loads typical of track-following applications.
