This carrier roller for Komatsu PC200-7 and PC200-8 excavators is designed to maintain proper track alignment and support the upper track chain during operation. As a critical top roller in excavator undercarriage systems, it helps guide the track smoothly, reducing vibration and minimizing uneven wear across the track chain and other components. As a high-quality replacement carrier roller for Komatsu PC200 series excavators, it plays a key role in stabilizing the track, maintaining correct chain tension, and extending overall undercarriage service life—especially in demanding conditions such as rocky, muddy, or sloped terrain. While bottom rollers carry the machine’s weight, this upper roller assembly for excavator track system ensures efficient track routing and improved operational control.
Premium Materials & Forging Technology for Longevity
To ensure maximum strength and wear resistance, each PC200-7 / PC200-8 carrier roller is crafted from high-grade 50Mn or 40Mn2 steel. Through one-piece hot forging and CNC machining, the roller body achieves excellent dimensional accuracy and toughness. The surface undergoes high-frequency induction hardening to reach HRC 52–58, giving it exceptional resistance to impact, abrasion, and deformation.
The internal shaft, seals, and bushings are also manufactured from hardened alloy steel, ensuring smooth rotation and oil retention throughout the roller’s service life.
High-Strength Materials and Heat-Treated Components
Every unit is built under a rigorous manufacturing protocol to guarantee reliability and performance:
- Forging and heat treatment to enhance core strength
- Precision CNC machining for dimensional accuracy
- Automated welding for shaft assembly and sealing zones
- Induction hardening of tread surfaces
- Grease filling, shaft assembly, and dual oil seal installation
- Full quality testing, including rotation resistance, hardness, and sealing
Our carrier rollers are tested under real-load simulations before leaving the factory to ensure performance in challenging field conditions.
