The function of the track roller is to convey the weight of an excavator to the ground. When an excavator is run on uneven ground, track rollers carry a tremendous impact. Therefore, the support of track rollers is huge. Moreover, if it is of poor quality and is often dusty, it needs a very good sealing to prevent dirt, sand, and water from damaging it.
