Function and Working Principle of R80-7 Track Rollers
The track roller (bottom roller) for Hyundai R80-7 excavators plays a crucial role in bearing the full weight of the equipment while ensuring smooth track movement. It maintains track tension and guides the undercarriage system during operation.
- It directly supports the track chain to ensure even ground contact.
- It stabilizes the excavator body during travel and digging operations.
- It reduces track vibration and wear by distributing load forces evenly.
High-Strength Materials & Heat Treatment
Our R80-7 track rollers are manufactured using premium 45# steel or 40Cr alloy steel. The roller surface undergoes high-frequency induction hardening to achieve a hardness level of HRC 52–58, ensuring excellent wear resistance and fatigue strength.
