Low Vibration Recirculating Ball Steering Box DZ9114470080 Black Anti-Corrosion Coated Power Steering Gear For Long Haul Trucks

Product Description

The DZ9114470080 recirculating ball power steering gear box serves as the core steering control component for heavy-duty trucks, adopting mature recirculating ball transmission structure to convert hydraulic pressure output from the steering pump into steering torque. It effectively lightens driver steering effort and delivers stable, responsive steering control under full vehicle load. The housing is integrally cast from high-strength cast iron with uniform black anti-rust coating, equipped with multiple standardized mounting lugs for frame fixation. The splined input shaft matches the original steering column perfectly, while internal precision ball circulation pairs reduce friction loss. This unit is fully pre-tested at factory; all hydraulic ports, mounting hole positions and spline parameters comply with OEM standards to support direct replacement without extra adjustment during steering system overhaul.

Key Product Advantages

• Robust cast iron one-piece housing with excellent compressive and shock resistance, resistant to chassis impact and heavy load deformation.
• Precision recirculating ball internal structure minimizes mechanical friction, achieving smooth steering, low noise and sensitive wheel response.
• Multi-position symmetrical mounting flange holes allow stable fixed installation, preventing steering box displacement during bumpy road travel.
• Sealed internal hydraulic chamber with high-performance rubber oil seals, effectively stopping power steering fluid leakage and extending service life.
• Standard splined input shaft with precise tooth profile, seamless matching with original steering column to eliminate abnormal rattling during turning.
