This cylindrical roller bearing carries a double row of full complement cylindrical rollers running against a particularly thick-walled outer ring and an inner ring, with the outer ring guided axially by the rolling elements themselves. Bore diameter is 50.0 mm, outside diameter 90.0 mm, and net mass is 0.954 kg. Sealing is provided on both sides by labyrinth seals (2LB), protecting the raceways from contamination without contact friction. The thick-walled outer ring construction gives the bearing high radial load carrying capacity and the ability to withstand shock loading, while the full complement roller set increases the number of load-bearing elements compared to a caged design. Axial guidance of the outer ring by the roller set allows the bearing to run directly as a track roller without a separate guiding flange arrangement. The double-sided labyrinth sealing permits reliable operation under grease lubrication in applications where the outer ring surface itself acts as the rolling and guiding track.
