Mid Roller

Under this category, BOLTRAC Midrollers  (also known as Boggie wheels or Track Rollers)serve as the core load-bearing components of the undercarriage system for tracked agricultural machinery, specifically engineered for high-horsepower tractors, combines, and forage harvesters. Their primary role is to manage vehicle weight distribution and ensure precise track guidance, maintaining stable travel and excellent tracking performance during field operations.

We offer a full range of OEM-standard and heavy-duty midrollers, including single-flange, double-flange, and rubber-coated configurations, widely compatible with major tracked agricultural machinery brands. Whether it's the bottom carrier rollers for John Deere 8RT/9RT series tractors, the intermediate midrollers for Case IH Quadtrac, the track support rollers for CLAAS Lexion harvesters, or the undercarriage guide rollers for New Holland CR series combines, there is a corresponding midroller solution available, ensuring seamless replacement and precise matching.
