This track roller guides along a mating track through a particularly thick-walled outer ring, with axial guidance of the outer ring provided by the balls themselves. The single row ball and cage assembly runs between the outer ring and inner ring, with a bore diameter of 10.0 mm, outside diameter of 32.0 mm, and height of 9.0 mm. Net mass is 0.05 kg. Sealing is designated 2RSR, with lip seals fitted on both sides. The thick-walled outer ring allows the roller to carry direct rolling contact loads while the integrated ball set handles axial positioning without a separate guiding element. The 2RSR sealing arrangement combines axial and radial sealing action, keeping contaminants out of the raceway and retaining the internal lubricant fill during operation along the guide track.
