This cylindrical roller bearing operates as a stud type track roller with a double row full complement roller set housed in a particularly thick-walled outer ring. A central rib on the outer ring provides axial guidance together with the rolling elements, while a solid roller stud with fixing thread and a mounting aid simplifies installation. Outside diameter is 52.0 mm, width 66.0 mm, and net mass 0.504 kg. The design follows the X-life concept, with no eccentric collar fitted. Sealing is provided on both sides by protected lip seals (2RS), keeping contamination out of the roller path and retaining lubricant within the bearing. The thick-walled outer ring combined with the full complement roller set allows the bearing to carry radial loads through direct rolling contact, and the axial guidance from the central rib eliminates the need for separate axial location of the outer ring. The threaded stud design allows direct mounting without a separate housing.
