This cylindrical roller bearing operates as a stud type track roller, built with a particularly thick-walled outer ring and a full complement of double row rollers running without a cage. The outer ring diameter is 52.0 mm and the overall width is 66.0 mm, with a net mass of 0.449 kg. A solid roller stud with a fixing thread and mounting aid forms the inner support, allowing direct bolted installation without a separate housing. The outer ring is guided axially by the rolling elements themselves, and there is no eccentric collar on this version. Sealing is provided by labyrinth seals on both sides (2LB), giving protection against contamination while keeping running resistance low. The full complement roller set increases radial load capacity compared to caged designs, and the thick-walled outer ring gives resistance against surface loading during rolling contact. The fixing thread and mounting aid simplify alignment and tightening during installation, making the roller suitable for direct mounting on flat guide surfaces where axial location by the rolling elements themselves is required.
