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 Komatsu D85 track roller is a vital undercarriage component designed to carry the full weight of the bulldozer and ensure smooth track movement on rough terrains. Built for durability and precision, this bottom roller guarantees high performance even under heavy loads and abrasive working conditions.
Each roller is meticulously engineered to withstand the constant ground contact and impact shocks encountered during dozing and grading operations. Whether the bulldozer is working on rocky soil, clay, or sand, the D85 roller ensures stability and reduces track wear, improving the overall efficiency of the machine.
Material & Heat Treatment
The D85 track roller is made from high-quality 50MN-45 or 50MN-40, known for its exceptional strength and toughness. The outer shell and shaft undergo deep hardening heat treatment, reaching a surface hardness of HRC 52–58 for superior resistance to wear and deformation.
- The roller body is forged and precisely machined to maintain dimensional accuracy.
- The shaft is induction-hardened for enhanced fatigue strength.
- The bushings are made of wear-resistant material to minimize internal friction and extend service life.
This advanced heat treatment process not only enhances wear resistance but also ensures excellent internal toughness, preventing cracking under high-impact operations.
Manufacturing Process of Komatsu D85 Track Rollers
Each Komatsu D85 roller is produced through a rigorous multi-step process to ensure consistent quality and reliability:
Heat Treatment
The roller body and shaft are heat-treated for strength and hardness.
Machining Process
Precision CNC machining ensures a perfect fit and smooth surface finish.
Assembly
Oil seals, shafts, and bushings are assembled under strict quality control standards.
Running Test
Each roller undergoes dynamic testing to confirm smooth rotation and sealing performance.
Paint Spraying
High-quality paint provides corrosion protection and a clean appearance.
Packing
Final inspection and packaging ensure safe transport and easy installation.
This systematic manufacturing process ensures that every roller performs consistently in the field.
