Premium Aluminum Casting Parts with Polishing and Deburring Techniques

Automotive Steering Knuckle (Wheel Hub Carrier)

• Casting process: Aluminum Gravity Casting with Sand Core
• Heat treatment: Sand Blast and T6 Heat Treatment
• CNC Precision Machining with Casting parts

Precision-forged from alloy steel, this critical load-bearing component supports sedans, SUVs, and light commercial vehicles. Featuring topology-optimized geometry with a static load capacity ≥12 tons and dynamic fatigue life beyond 500,000 cycles, it ensures steering accuracy and suspension stability. The knuckle's hardened ball joint holes (HRC 45-50) and hub bearing seats fit MacPherson/multi-link suspensions, minimizing chassis noise risks.

Designed to meet OEM standards, this knuckle supports wheel bolt pattern customization (5×108 to 5×130) and ABS sensor ports. Its zinc-nickel coating provides 1000-hour salt spray resistance for harsh environments. The axle knuckle integrates steering linkage and shock absorber mounts, using a lightweight hollow design (25% weight reduction) for enhanced handling responsiveness.
