Product Function and Working Principle of PC700 Track Roller
The bottom roller plays a critical role in the undercarriage system of the Komatsu PC700 excavator. It supports the entire weight of the machine while facilitating the movement of the track chain over rough terrain. By reducing friction and absorbing ground shock, it ensures operational stability and extends the life of the undercarriage system.
Track Roller Materials Used and Manufacturing Craftsmanship
Our PC700 track rollers are made from high-strength alloy steel, typically 45# steel or 42CrMo. Key processes include:
- Forged Roller Body: Ensures core strength and resistance to deformation.
- Surface Induction Hardening: Achieves HRC 52–58 hardness, enhancing wear resistance.
- Precision Machining: Guarantees tight dimensional tolerance and smooth operation under high load.
Advanced Manufacturing Process of PC700 Bottom Roller
To ensure consistency and performance, each Komatsu PC700 track roller undergoes a step-by-step manufacturing process: standards. This ensures dependable performance in high-load excavation environments.
