NUKR62-X-A is a stud type track roller built as a double row cylindrical roller bearing with a full complement cylindrical roller set and a particularly thick-walled outer ring. Outside diameter is 62.0 mm, width 80.0 mm, and net mass is 0.756 kg. The roller stud is solid, fitted with a fixing thread and a mounting aid, and the outer ring is guided axially by the rolling elements rather than by an eccentric collar. Sealing is provided by labyrinth seals (2LB) on both sides. The full complement roller set gives high radial load capacity within the compact envelope defined by the stated diameter and width, while the thick-walled outer ring withstands the surface loading typical of direct rolling contact on a track. Axial guidance through the rolling elements keeps the outer ring centered without an additional flange ring, and the double-sided labyrinth seals limit contamination ingress while retaining grease inside the roller.
