Product Introduction

The 81.46701.6112 power steering gear box is a hydraulic steering system component designed for MAN retrofit and HOWO-compatible heavy-duty truck platforms. It is used to convert steering wheel input into precise hydraulic-assisted steering movement, ensuring stable and accurate control of the front axle under heavy-load and complex operating conditions.

This model is commonly applied in retrofit and export truck configurations where MAN-based steering systems are adapted to HOWO platforms or mixed chassis structures. It provides reliable steering performance under continuous heavy-duty operation, significantly reducing steering effort while maintaining directional stability and responsiveness.

The housing is manufactured from high-strength cast iron material, ensuring resistance to hydraulic pressure, vibration, and long-term mechanical stress. Internal precision-machined components provide smooth hydraulic response, reduced wear, and long service life in demanding environments.

Each unit is strictly tested for hydraulic sealing performance, pressure endurance, steering accuracy, and durability to meet OEM-level standards for heavy commercial vehicle applications.
