Product Descreiption

The Dongfeng Kinlong KC Rear Wheel Hub is a premium-grade component engineered for the rear axle of Dongfeng’s medium- and heavy-duty commercial vehicles, including trucks, buses, and specialized transport equipment. Designed to deliver exceptional load-bearing capacity, durability, and smooth operation, this wheel hub is a critical element in ensuring vehicle stability, safety, and longevity. Built to Dongfeng’s rigorous OEM standards, the Kinlong KC rear wheel hub combines advanced materials, precision manufacturing, and optimized design to meet the demands of modern logistics, construction, and industrial applications.

Key Specifications

  1. Application Compatibility:
    • Vehicle Models: Fits Dongfeng’s Kinlong series trucks (e.g., DFL5251, DFH5311), as well as other heavy-duty models like Tianlong, KR, and D9 series (6×4, 8×4, and 4×2 configurations).
    • Axle Type: Designed for rear drive axles with drum or disc brake systems (e.g., 13-ton or 16-ton capacity axles).
  2. Material & Construction:
    • Hub Body: High-strength nodular cast iron (e.g., QT500-7) or forged alloy steel for superior load distribution and impact resistance.
    • Bearings: Double-row tapered roller bearings (e.g., 32300 series) pre-lubricated with high-performance grease for low-friction operation and extended service life.
    • Seals: Heavy-duty triple-lip rubber seals or metal-clad seals to prevent contamination from dust, water, and debris.
  3. Dimensions:
    • Outer Diameter: ~280–300 mm (11.02–11.81 inches) (varies by configuration).
    • Bolt Circle Diameter (PCD): 10 x 285 mm (10-bolt pattern, 285 mm pitch circle diameter) or 8 x 275 mm (customizable for specific axles).
    • Center Bore: ~160–170 mm (6.30–6.69 inches).
    • Hub Width: ~180–200 mm (7.09–7.87 inches).
    • Weight: ~35–45 kg (77.2–99.2 lbs) (depending on material and design).
  4. Load Rating:
    • Static Load Capacity: Up to 16,000 kg (35,274 lbs) per hub (designed for GAWR ≤32,000 kg rear axles).
    • Dynamic Load Rating: Compliant with ISO 28580:2018 and GB/T 5920 standards for commercial vehicle wheel hubs.
  5. Lubrication:
    • Grease Compatibility: Recommended NLGI Grade 2 lithium-complex grease for high-temperature and water-resistant performance.
    • Grease Fitting: Zerk-type fitting for easy maintenance and re-lubrication.

Technical Features

  1. High Load-Bearing & Impact Resistance:
    • Reinforced rib design and optimized cross-section reduce stress concentration, preventing deformation under heavy loads or uneven terrain.
    • Suitable for applications with frequent starts/stops, overloading risks, or off-road use.
  2. Enhanced Durability:
    • Corrosion-resistant coatings (e.g., zinc plating or epoxy primer) protect against rust in harsh environments (e.g., coastal regions, construction sites).
    • Heat-treated bearing races and rollers resist fatigue and wear, extending service intervals.
  3. Precision Engineering:
    • Tight tolerances (≤0.02 mm runout) ensure smooth wheel rotation and reduced vibration.
    • Compatible with ABS (Anti-lock Braking System) or EBS (Electronic Braking System) sensors for improved safety and braking control.
  4. Easy Maintenance:
    • Modular design allows for quick bearing and seal replacement without hub disassembly (in some configurations).
    • Pre-installed bearings and seals reduce installation time and labor costs.
