OEM Kato HD400SE/HD450SE/HD550 Excavator Top Roller Excavator Upper Roller

Traction: The carrier roller guides the track chain and helps to maintain optimal tension, which improves traction and allows the excavator to move easily over rough or uneven terrain. A damaged or worn-out carrier roller can reduce traction, making it more difficult to operate the excavator.

Efficiency: A properly functioning carrier roller helps to reduce friction between the track chain and the undercarriage, which improves efficiency and reduces fuel consumption. This can result in lower operating costs and improved productivity.
