Track roller

There are single flange type and double flange type rollers which are installed to a track frame. The rollers roll on the track link assembly under heavy load of machine weight. Track rollers are installed, not to warp the link, but to bear the machine weight and distribute evenly over the track shoes.

Bushing and roller shaft are lubricated by oil. Track rollers installed near idler and sprocket are single flange rollers. The order of installation of single or double flange rollers are decided depends upon machine size. The flange of the track roller guides the track link assembly to prevent it from moving in a 'zig-zag' manner. The hardness of the flange has to be improved for abrasion resistant because the flange rubs against the side of the track links.
