Product Description

E303/E345 Track Roller Yellow Color Bulldozer Spare Parts

The track roller plays a vital role in tracked engineering machinery, being an indispensable key component that ensures stable operation and efficient performance of the machinery.

High precision:

The manufacturing process of the supporting wheel begins with welding the wheel body, which is then subjected to a meticulous machining procedure utilizing a dedicated vertical CNC lathe solely for this component. This meticulous approach guarantees precise concentricity of the wheel body, resulting in substantial quality improvements compared to wheel bodies that only undergo partial machining after welding.

High lifespan:

This approach guarantees uniform contact and seamless operation within the wheel, thereby effectively reducing issues of accelerated localized wear. Consequently, it plays a crucial role in significantly extending the overall durability of the product.

Sealing and lubrication:

Designed to endure both tropical and cold climates, the product incorporates high-quality, standardized floating oil seals and lubrication systems. These components empower the supporting wheels to maintain an excellent seal without the requirement for maintenance, even in demanding operational conditions or within a broad temperature spectrum ranging from -45°C to 120°C.
