This yoke type track roller functions as a cylindrical roller bearing with a particularly thick-walled outer ring, a full complement cylindrical roller set and an inner ring. Bore diameter is 17.0 mm, outside diameter 40.0 mm, net mass 0.147 kg. The outer ring is guided axially directly by the rolling elements, and both sides are closed with 2LB labyrinth seals, as specified for NUTR17-X-A. The full complement roller set gives higher radial load capacity for the given envelope, while axial guidance by the rolling elements keeps the outer ring track running true without a separate flange. The labyrinth seals on both faces protect the roller set from contamination, and the inner ring allows direct shaft mounting.
