The track roller plays a vital role in tracked engineering machinery, ensuring stable operation of the machine and boosting its overall performance efficiency.

High precision:

The production of the supporting wheel initiates with the welding of its body. Subsequently, it undergoes precise machining using a specialized vertical CNC lathe tailored for this component. This meticulous process ensures accurate and concentric alignment of the wheel body, leading to substantial quality improvements compared to wheel bodies that receive minimal machining post-welding.

High lifespan:

• This method ensures constant wheel engagement and smooth operation, effectively addressing problems associated with rapid localized wear. As a result, it plays a crucial role in significantly enhancing the overall durability of the product.

Sealing and lubrication:

Designed to provide dependable performance in both tropical and cold environments, the product features high-quality floating oil seals and sophisticated lubrication systems. These attributes allow the supporting wheels to retain an exceptional seal without the requirement for maintenance, even when exposed to extreme operational conditions or temperatures spanning from -45°C to 120°C.
