Key Information

The upper roller is responsible for supporting the weight of the track chain between the idler and the sprocket, preventing the track from sagging excessively and ensuring smooth, stable movement of the crawler assembly.

It maintains proper track tension and alignment. By supporting the upper run of the track, it reduces friction and prevents the track chain from hitting the track frame, which protects both the chain links and the frame structure.
