Carrier roller

There are mainly two types of carrier rollers, flange type and flat type. The flange type roller is used for medium and large size bulldozers, and dozer shovels. The flat type roller is used for small size hydraulic excavators.

Since the carrier rollers support only the shoe assembly, the structure is less complicated compared to the track rollers. However, the accumulation of sand and soil around the carrier rollers will also cause higher wear. when operating a machine at a high speed. This will cause the track links to hit the carrier rollers strongly and as a result, it will shorten the life of both items. The bearing and the shaft in the carrier roller are lubricated with oil.
