EX55/EX400 HRC53-57 8-12MM Bulldozer Track Roller For Undercarriage Parts 9129347

The track roller is a crucial element in tracked engineering machinery, serving as an indispensable component that guarantees stable machinery operation and efficient performance.

High precision:

The production of the supporting wheel commences with the welding of its body, followed by a detailed machining process carried out using a specialized vertical CNC lathe exclusively for this part. This precise methodology ensures accurate concentricity of the wheel body, leading to significant enhancements in quality when compared to wheel bodies that only undergo limited machining post-welding.

High lifespan:

• This methodology ensures even contact and smooth functioning within the wheel, effectively minimizing problems of localized wear acceleration. As a result, it is essential in substantially enhancing the overall lifespan of the product.

Sealing and lubrication:

Engineered to withstand both tropical and cold climates, the product features high-quality, standardized floating oil seals and lubrication systems. These components allow the supporting wheels to maintain a superior seal without the need for maintenance, even in harsh operational conditions or across a wide temperature range from -45°C to 120°C.
