The Bobcat 337 Track Roller is a critical part of the undercarriage system, ensuring smooth track movement and stable ground contact. As one of the main load-bearing components, it distributes the machine’s weight, minimizes vibration, and helps maintain efficient traction across different terrains. A strong and durable track roller is essential for keeping your Bobcat 337 operating reliably and reducing long-term maintenance costs.
Material & Manufacturing Process
Our Bobcat 337 track rollers are manufactured from high-strength forged alloy steel, chosen for its toughness and resistance to wear. The roller body undergoes CNC precision machining, ensuring accurate dimensions and a perfect fit with the track chain. Each roller is then induction heat-treated to achieve surface hardness of HRC 52–58, providing excellent resistance against impact, abrasion, and deformation.
The complete manufacturing process includes:
Heat Treatment
Enhances surface hardness and structural integrity
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
