This cylindrical roller bearing carries a bore diameter of 45.0 mm, an outside diameter of 100.0 mm and a net mass of 1.387 kg. The design features a particularly thick-walled outer ring guided axially by the rolling elements, a double row of full complement cylindrical rollers, and an inner ring. Sealing is provided on both sides by labyrinth seals (2LB), protecting the raceways from contamination without adding friction from contact seals. The thick-walled outer ring and full complement roller set give this bearing a high load carrying capacity for its size, while the axial guidance of the outer ring through the rolling elements allows it to run directly on a track surface without a separate guiding flange. The double-sided labyrinth sealing supports operation under grease lubrication in applications where the outer ring surface itself acts as the rolling contact path.
