2000 Working Hours HRC53-57 50mn Undercarriage Parts Bulldozer Track Roller For Hengte 120

The track roller is a vital part in tracked engineering machinery, guaranteeing stable machinery operation and boosting its overall efficiency.

High precision:

The manufacturing of the supporting wheel initiates with the welding of its body. Afterward, it undergoes a meticulous machining procedure utilizing a specialized vertical CNC lathe designated solely for this component. This precise approach guarantees accurate concentric alignment of the wheel body, resulting in notable quality advancements compared to wheel bodies that only undergo minimal machining after welding.

High lifespan:

• This approach guarantees continuous wheel engagement and seamless operation, effectively resolving issues related to accelerated localized wear. Consequently, it plays a vital role in significantly boosting the overall durability of the product.

Sealing and lubrication:

Engineered for reliable performance across both tropical and cold environments, the product boasts high-quality floating oil seals and superior lubrication mechanisms. These features enable the supporting wheels to maintain an excellent seal without the need for maintenance, even under extreme operational conditions or within a broad temperature spectrum ranging from -45°C to 120°C.
