What is the Sitrak VGD71 Front Wheel End Assembly(Φ335,ABS)

  • Sitrak VGD71 Front Wheel End Assembly (Φ335, ABS): Heavy-Duty Performance with Advanced Safety Integration​
  • Engineered for commercial vehicles demanding precision, durability, and safety, the Sitrak VGD71 Front Wheel End Assembly (Φ335, ABS) is a premium solution designed to deliver seamless wheel support, efficient braking, and anti-lock braking system (ABS) compatibility. With a 335mm diameter optimized for heavy payloads, this assembly integrates high-quality components to ensure reliable operation in the most challenging road conditions.​
  • Core Components for Robust Wheel Support​
  • The Front hub assembly (ABS), forged from high-strength alloy steel, forms the structural backbone, providing a secure mounting platform for the wheel and brake system. It houses Tapered roller bearings (double-row design), heat-treated to withstand extreme radial and axial loads while minimizing friction during high-speed rotation. These bearings, lubricated with HP-R grease, offer superior anti-wear properties, extending service life by up to 20% compared to standard greases, even under continuous heavy-duty use.​
  • Reliable Braking and ABS Integration​
  • A cast-iron Brake drum (Φ335mm) ensures consistent stopping power, its heat-resistant surface minimizing brake fade during prolonged use. Cross recessed countersunk head screws and Hexagon head bolts M8 (zinc-plated for corrosion resistance) secure the drum to the hub, with torque-controlled installation ensuring uniform contact and reduced vibration. The hub’s integrated ABS ring (compatible with front axle wheel speed sensors) enables real-time wheel speed monitoring, critical for preventing lockup and enhancing stability on wet, icy, or uneven terrain.​
  • Sealing and Protection for Longevity​
  • A Hub Oil Seal, constructed from oil-resistant NBR rubber with a steel reinforcing ring, creates an airtight barrier against lubricant leakage and contaminant ingress, protecting bearings from dust, water, and road debris. Sealing washers at flange connections further ensure leak-free operation, while the Hub end cap (aluminum alloy with a corrosion-resistant coating) shields the hub’s inner components from external impacts and environmental damage.​
  • Secure Fastening and Adjustment​
  • Lock nuts and Cotter pins provide a fail-safe mechanism to secure the hub to the axle, eliminating axial play and preventing accidental disassembly during aggressive maneuvers. Thrust washers distribute clamping force evenly across bearing races, reducing stress concentrations, while Tapered roller bearing adjustments (via precision shims, not shown) ensure optimal preload for smooth rotation. These components, all rated for 10.9-grade strength, meet OEM specifications for safety and reliability.​
  • Design for Maintenance Efficiency​
  • The assembly’s modular architecture allows for straightforward component replacement, with accessible grease nipples enabling routine lubrication without disassembling the hub. The brake drum’s friction surface is precision-machined to OE tolerances, ensuring compatibility with standard brake shoes and minimizing installation time. This design is ideal for fleet managers prioritizing minimal downtime and cost-effective maintenance.​
  • SEO-Optimized Features for Commercial Relevance​
  • Keyword Precision: Prioritizes “VGD71 Front Wheel End Assembly”, “Φ335”, “ABS”, and component names to target exact-match searches in parts catalogs and technical databases.​
  • Technical Depth: Highlights material science (alloy steel, NBR seals), lubrication technology (HP-R grease), and safety features (ABS integration) to attract mechanical professionals and fleet engineers.​
  • Benefit-Driven Messaging: Emphasizes load-bearing capacity, corrosion resistance, and maintenance ease, addressing core concerns for commercial vehicle operators.​
  • In summary, the Sitrak VGD71 Front Wheel End Assembly (Φ335, ABS) combines rugged engineering with advanced safety features, delivering unmatched performance for trucks, buses, and industrial machinery. Trust in its precision-manufactured components and ABS compatibility to ensure stable wheel operation, efficient braking, and long-term durability—backed by Sitrak’s commitment to excellence in commercial vehicle solutions.
