Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The carrier roller, also known as the upper roller, is an important part of the Kubota U25 undercarriage system. While bottom rollers support the machine’s weight on the ground, the carrier roller is mounted above the track to:
- Guide the track chain and keep it in proper alignment.
- Reduce track sagging for smoother movement.
- Minimize uneven wear on the track links.
- Improve operator comfort by reducing vibration and noise.
Without a strong and properly functioning carrier roller, the excavator risks higher track wear, misalignment, and increased undercarriage maintenance costs.
