This cylindrical roller bearing carries a double row of full complement cylindrical rollers running against a particularly thick-walled outer ring, with a separate inner ring mounted on the shaft. The outer ring is guided axially directly by the rolling elements, giving the unit its yoke type track roller function. Bore diameter is 40.0 mm, outside diameter 80.0 mm, and net mass is 0.816 kg. Sealing on both sides is of the 2LB labyrinth type. The thick-walled outer ring combined with the full complement roller set gives this bearing a high radial load capacity relative to its envelope size, while the axial guidance provided by the rollers themselves eliminates the need for a separate flange for that function. The labyrinth seals on both sides restrict ingress of contaminants while allowing continuous relubrication with grease, making the bearing suitable for track roller applications where the outer ring rolls along a rail or cam surface under radial loading.
