This cylindrical roller bearing guides loads through a double row of full complement cylindrical rollers running on a particularly thick-walled outer ring and an inner ring, with the outer ring axially guided by the rolling elements themselves. Bore diameter is 20.0 mm, outside diameter 47.0 mm, and net mass 244.0 g. Sealing is provided on both sides by labyrinth seals (2LB), keeping contamination out while allowing the rolling elements to maintain axial guidance. The thick-walled outer ring and full complement roller set give NUTR20-A a high load-carrying capacity for its size, while the double row layout supports both radial forces and the axial guidance function inherent to yoke type track rollers. The labyrinth seals on both sides protect the internal rolling elements without contact friction, making the bearing suitable for applications where the outer ring itself acts as the running surface and axial guidance is required directly from the bearing construction.
