This track roller carries load through a single row of self-retaining balls running between a particularly thick-walled outer ring and an inner ring, with the ball and cage assembly guiding the outer ring axially against the balls. Bore diameter is 25.0 mm, outside diameter 62.0 mm, height 15.0 mm, and net mass 0.23 kg. Sealing on both sides is provided by lip seals (2RSR), combining axial and radial sealing action. The thick-walled outer ring gives the roller a running surface able to withstand direct rolling contact loads, while the built-in axial guidance through the ball set keeps the outer ring positioned without extra retaining components. The double-sided lip seals restrict ingress of contaminants and retain internal lubricant, making the bearing suitable for direct mounting as a cam or track follower where a shaft-mounted rolling element is required.
