This cylindrical roller bearing carries a double row of full complement cylindrical rollers running against a particularly thick-walled outer ring with a central rib. The rib guides the outer ring axially together with the rolling elements, while an inner ring completes the assembly. Bore diameter is 30.0 mm, outside diameter 72.0 mm, and net mass is 0.68 kg. Sealing is provided by protected lip seals on both sides (2RS), and the design follows the X-life concept. The full complement roller set gives high radial load carrying capacity within the available cross-section, and the thick-walled, rib-guided outer ring allows the bearing to run directly as a track roller without a separate housing guiding the outer race. The double-sided lip seals keep contamination out and retain grease inside the bearing, supporting grease lubrication without additional external sealing measures. The axial guidance through the central rib and rolling elements makes this bearing suitable for applications where the outer ring itself acts as the rolling surface and must be positioned axially by the bearing construction.
