VIVI40 40Mn2 HRC53-57 Track Bottom Roller Lower Roller Bulldozer Track Roller For Undercarriage Parts

High precision:

The manufacturing of the supporting wheel entails welding the wheel body first, and subsequently, precise machining is conducted on this singular component using a vertical CNC lathe. This meticulous process guarantees impeccable concentricity of the wheel body, thereby providing substantial quality advancements over wheel bodies that have undergone only partial machining after welding.

High lifespan:

This approach guarantees uniform contact and seamless operation within the wheel, thereby effectively preventing issues of localized accelerated wear. Consequently, it plays a crucial role in substantially enhancing the overall longevity 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 enable the supporting wheels to maintain a perfect seal without requiring maintenance, even in severe working conditions or across temperature extremes ranging from -45°C to 120°C.
