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 for the Komatsu D60 bulldozer plays a key role in maintaining the stability of the undercarriage system. Positioned above the track chain, it supports the upper track links, prevents track sagging, and ensures smooth machine operation. Without a reliable carrier roller, the track chain would be exposed to uneven wear, leading to increased maintenance costs and reduced bulldozer productivity. A strong, well-engineered carrier roller extends the life of both the track chain and the entire undercarriage assembly.
Material and Heat Treatment
To ensure maximum durability, the Komatsu D60 carrier roller is made from high-strength alloy steel. The roller surface undergoes deep heat treatment to achieve hardness of HRC 52–58, improving resistance to wear and impact. At the same time, the core remains tough enough to absorb shocks during heavy dozing operations.
Key steps include:
- Forged steel body for structural strength.
- Advanced heat treatment for extended service life.
- CNC machining for precise dimensions and accurate fit.
- High-quality seals to keep lubricant inside and contaminants out.
