This cylindrical roller bearing carries a bore diameter of 20.0 mm, an outside diameter of 47.0 mm and a net mass of 0.239 kg. It is built as a double row full complement cylindrical roller set with a particularly thick-walled outer ring featuring a central rib, which guides the outer ring axially together with the rolling elements, and a separate inner ring. Sealing is provided by protected lip seals on both sides (2RS), and the design follows the X-life concept, indicated by the XL suffix. The thick-walled outer ring with integral central guiding rib makes this bearing suitable for applications where the outer ring itself acts as a track roller running directly on a mating surface, with axial guidance built into the bearing rather than requiring external flanges. The full complement roller set increases the number of load-carrying elements compared to a caged design, raising the load capacity within the same envelope dimensions. The two-sided lip seals keep contaminants out and retain lubricant, allowing the bearing to run with grease lubrication in exposed positions without additional external sealing.
