The track roller serves as a crucial element in tracked engineering machinery, guaranteeing stable machine operation and enhancing its overall performance efficiency.

High precision:

The manufacturing of the supporting wheel begins with the welding of its body. Following this, it undergoes precise machining using a dedicated vertical CNC lathe specifically designed for this component. This meticulous approach guarantees accurate and concentric alignment of the wheel body, resulting in significant quality enhancements compared to wheel bodies that undergo minimal machining after welding.

High lifespan:

• This approach guarantees consistent wheel engagement and seamless operation, effectively tackling issues related to rapid localized wear. Consequently, it plays a vital role in substantially boosting the overall durability of the product.

Sealing and lubrication:

Engineered for reliable performance across both tropical and cold climates, the product boasts high-quality floating oil seals and advanced lubrication systems. These features enable the supporting wheels to maintain an exceptional seal without the need for maintenance, even when subjected to extreme operational conditions or temperatures ranging from -45°C to 120°C.
