What is the Sitrak Steering Knuckle Arms And Accessories (R282/124-φ30)

  • Sitrak Steering Knuckle Arms And Accessories (R282/124-φ30): Heavy-Duty Precision for Steering Control
  • Engineered to deliver unmatched durability and steering precision, the Sitrak Steering Knuckle Arms And Accessories (R282/124-φ30) are critical components for commercial vehicles, ensuring reliable force transmission and responsive handling in the most demanding environments. Designed for heavy-duty trucks, buses, and industrial machinery, this assembly pairs a robust Steering knuckle arm with high-strength Hexagon head bolts M18*1.5, combining rugged construction with precision engineering to withstand extreme mechanical stress.
  • Core Component: Steering Knuckle Arm
  • The Steering knuckle arm, forged from premium-grade alloy steel, serves as the vital link between the steering tie rod and the wheel knuckle. Its R282/124-φ30 specification denotes a 282mm overall length, 124mm mounting span, and a 30mm bore diameter—precision-engineered to align with the geometry of heavy-duty front axles. The arm’s reinforced I-beam design distributes steering forces evenly, minimizing stress concentrations and resisting bending or fatigue, even under maximum payloads or sharp turns. A shot-peened surface treatment enhances its fatigue resistance by 20%, while a dual-layer epoxy-zinc coating protects against rust and corrosion in salted roads or high-moisture environments.
  • Secure Mounting with Hexagon Head Bolts M18*1.5
  • Included with the assembly are Hexagon head bolts M18*1.5, high-tensile fasteners rated at 10.9-grade strength to ensure a secure, vibration-resistant connection between the steering knuckle arm and wheel knuckle. With an 18mm diameter, 1.5mm pitch, and zinc-nickel plating, these bolts deliver exceptional clamping force while resisting thread stripping and corrosion. Their hexagonal flange design provides a larger bearing surface for uniform load distribution, reducing the risk of stress-induced fractures and ensuring long-term structural integrity.
  • Design for Commercial Vehicle Excellence
  • The R282/124-φ30 assembly is optimized for compatibility with Sitrak VGD-series front axles and steering systems, ensuring seamless integration with components like the VGD71 Steering Shaft Assembly and VGD75 Front Axle Assembly. The steering knuckle arm’s precision-machined spline and bore ensure zero play during steering input, translating to tighter handling and reduced tire wear. This level of engineering is critical for vehicles navigating urban traffic, off-road terrain, or high-speed highways, where precise control and reliability are non-negotiable.
  • SEO-Optimized Features for Professional Users
  • Keyword Precision: Prioritizes product model (R282/124-φ30), component names (Steering knuckle arm, Hexagon head bolts M18*1.5), and technical specs to dominate exact-match searches in parts catalogs and maintenance guides.
  • Technical Benefits: Emphasizes fatigue resistance, corrosion protection, and load distribution to address fleet managers’ key concerns about downtime and maintenance costs.
  • Application Clarity: Explicitly targets heavy-duty trucks, buses, and industrial machinery, appealing to mechanical professionals and OEM buyers seeking proven components.
  • Easy Maintenance and Safety Assurance
  • The assembly’s modular design allows for straightforward installation and torque validation, with clear OEM specifications for tightening sequences. The steering knuckle arm and bolts undergo rigorous magnetic particle inspection to ensure defect-free performance, while the bolt’s thread-locking compound prevents loosening during dynamic maneuvers. These features make the R282/124-φ30 assembly a trusted choice for fleets prioritizing safety, compliance, and operational efficiency.
  • In summary, the Sitrak Steering Knuckle Arms And Accessories (R282/124-φ30) set a standard for heavy-duty steering reliability, combining a rugged alloy steel arm with high-strength fasteners to deliver precise, durable performance. Trust in their engineered excellence to keep your vehicle’s steering system operating at peak efficiency, mile after challenging mile.
