The track roller, also known as the bottom roller, plays a crucial role in maintaining the stability and mobility of the Yanmar VIO30 mini excavator. It guides the track chain, supports the weight of the machine, and ensures steady movement across uneven or rocky terrain. A well-built track roller minimizes vibration, prevents premature wear on the track system, and improves fuel efficiency during excavation or construction work.
Materials & Heat Treatment
Each Yanmar VIO30 track roller is crafted from high-grade forged alloy steel. After machining, the surface undergoes deep induction hardening, ensuring a hardness of HRC52–58. This process provides excellent wear resistance while maintaining a tough core to absorb shocks. The roller shell and shaft are further treated with precision grinding and anti-rust coating, extending service life even under heavy-duty use.
Manufacturing Process
Our rollers are produced through a strict multi-step process:
Heat Treatment
Machining Process
CNC turning and milling ensure dimensional accuracy
Assembly
Running Test
Simulated load test to verify functionality
Paint Spraying
Anti-rust coating for surface protection
