131401020703B Middle Axle Sany SAT40C Articulated Dump Truck spare parts

This product is a dedicated center axle assembly for dump trucks, a core component for chassis stress and transmission. It can distribute heavy loads across the vehicle, smoothly transmit driving power, and constrain chassis deformation. It effectively improves issues such as vehicle misalignment, chassis swaying, transmission noise, and driving vibration, stabilizing chassis conditions and ensuring smooth and safe heavy-load driving and unloading operations.
The central axle is precision forged from high-strength alloy structural steel, and treated with tempering hardening, precision grinding, and stress relief processes. This results in a rigid and dense axle with excellent resistance to torsion, impact, and fatigue, making it resistant to bending, deformation, and fracture under long-term alternating heavy loads. The surface is treated with rust-proof and weather-resistant materials to resist corrosion from construction site mud, water, and dust, allowing for continuous, high-intensity operation in all weather conditions. Precision machining at the original factory ensures dimensions and assembly accuracy perfectly match the original vehicle standards, resulting in a tight fit and balanced stress distribution, eliminating the need for grinding, modification, or secondary adjustments. This avoids chassis failures caused by assembly deviations, reduces maintenance downtime, and is suitable for the repair, refurbishment, and bulk stocking of Sany mining dump trucks.
