This cylindrical roller bearing carries radial loads through a double row of full complement cylindrical rollers running between a particularly thick-walled outer ring and an inner ring. The outer ring is guided axially by the rolling elements themselves, giving the bearing its track roller function. Bore diameter is 15.0 mm, outside diameter 35.0 mm, and net mass 99.0 g. Sealing is provided by labyrinth seals on both sides, designation 2LB. The thick-walled outer ring gives the raceway surface enough material to withstand rolling contact under radial load while running directly as a track surface. The full complement roller set increases the number of load-carrying elements compared to a caged design, raising radial load capacity for a given envelope size. The labyrinth seals on both sides keep contaminants out of the raceway without adding contact friction, which suits continuous rolling operation where the outer ring surface itself serves as the running track.
