The track roller occupies a crucial role in tracked engineering machinery, serving as an essential element that guarantees stable machinery operation and enhances overall efficiency.

High precision:

The production of the supporting wheel begins with the welding of its body, followed by a meticulous machining process carried out using a specialized vertical CNC lathe exclusively for this part. This precise methodology ensures that the wheel body is accurately aligned concentrically, leading to significant quality enhancements compared to wheel bodies that only undergo minimal machining post-welding.

High lifespan:

• This methodology ensures consistent contact and smooth functioning of the wheel, efficiently mitigating problems associated with rapid localized wear. As a result, it is crucial in substantially prolonging the overall lifespan of the product.

Sealing and lubrication:

Crafted for dependable performance across both tropical and cold climates, the product features top-tier floating oil seals and lubrication systems of exceptional quality. These attributes allow the supporting wheels to maintain a superior seal with zero maintenance requirements, even when subjected to extreme operational conditions or within a wide temperature spectrum ranging from -45°C to 120°C.
