Product Introduction

The WG9725470082 power steering gear box is a hydraulic steering system component designed for SINOTRUK HOWO 8×4 dump trucks. It converts steering wheel input into precise hydraulic-assisted movement, ensuring stable and accurate steering control under heavy-load and off-road working conditions.

This model is widely used in construction and mining dump truck applications, where vehicles operate under extreme payloads and frequent low-speed maneuvering. The hydraulic system significantly reduces steering effort while maintaining strong directional stability and control.

The housing is manufactured from high-strength cast iron material, providing excellent resistance to pressure, impact, and long-term hydraulic load. Internal precision-machined components ensure smooth steering response and reliable performance in harsh environments.

Each unit is strictly tested for hydraulic sealing, pressure endurance, steering accuracy, and durability to meet OEM standards for heavy-duty truck applications.
