The track roller holds a pivotal position in tracked engineering machinery, functioning as a vital component that ensures stable machinery operation and efficient overall performance.

High precision:

The manufacturing of the supporting wheel starts with welding its body, which is then subjected to a detailed machining process utilizing a specialized vertical CNC lathe dedicated solely to this component. This precise approach guarantees precise concentric alignment of the wheel body, resulting in substantial improvements in quality compared to wheel bodies that undergo only limited machining after welding.

High lifespan:

• This approach guarantees uniform contact and seamless operation within the wheel, effectively reducing issues related to accelerated localized wear. Consequently, it plays a vital role in significantly extending the product's overall lifespan.

Sealing and lubrication:

Designed to perform reliably in both tropical and cold climates, the product incorporates high-standard floating oil seals and lubrication systems of superior quality. These features enable the supporting wheels to maintain an excellent seal without requiring maintenance, even under severe operational conditions or within a broad temperature range spanning from -45°C to 120°C.
