Product Descreiption
The Dongfeng T38A0 Rear Wheel Hub is a high-performance, heavy-duty component engineered for the rear axle systems of Dongfeng’s medium- and heavy-duty commercial trucks. Designed to withstand extreme loads, harsh operating conditions, and rigorous daily use, the T38A0 wheel hub ensures reliable power transmission, precise wheel alignment, and extended service life. Built to Dongfeng’s strict OEM standards, this wheel hub combines robust materials, precision manufacturing, and advanced engineering to deliver exceptional durability, safety, and operational efficiency.
Key Specifications
- Application Compatibility:
- Vehicle Models: Fits Dongfeng’s popular truck series, including the DFL5160, DFL5250, Tianlong KL, KR, and D7 models (4×2, 6×4, and 8×4 configurations).
- Axle Type: Designed for rear drive axles with 10-ton to 16-ton capacity, compatible with Dongfeng’s standard rear axle assemblies.
- Material & Construction:
- Hub Body: High-strength nodular cast iron (e.g., QT450-10 or FCD450) for superior tensile strength and impact resistance.
- Bearings: Double-row tapered roller bearings (e.g., 32218 or equivalent) pre-loaded for optimal load distribution and reduced friction.
- Sealing: Triple-lip oil seals and dust caps to prevent contamination and extend bearing life.
- Surface Treatment: Anti-corrosion coating (e.g., zinc phosphate or electro-deposition paint) for rust resistance in harsh environments.
- Dimensions:
- Outer Diameter: ~380–400 mm (14.96–15.75 inches) (hub flange diameter).
- 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) (matches axle spindle diameter).
- Width (Hub Face to Flange): ~180–200 mm (7.09–7.87 inches).
- Weight: ~30–40 kg (66.1–88.2 lbs) (depending on configuration).
- Load & Torque Ratings:
- Static Load Capacity: Up to 16,000 kg (35,274 lbs) per hub (designed for GVWR ≤32,000 kg rear axles).
- Dynamic Load Rating: Meets ISO 8643:2011 and GB/T 12230 standards for heavy-duty commercial vehicle wheel hubs.
- Maximum Torque: 12,000–15,000 N·m (8,850–11,060 lb·ft) (depending on axle ratio).
Technical Features
- Enhanced Durability:
- Nodular cast iron construction resists cracking and deformation under heavy loads.
- Heat-treated bearing races and rollers ensure long-term reliability under high-speed rotation.
- Precision Engineering:
- Tight tolerances (≤0.05 mm runout) ensure smooth wheel rotation and reduced vibration.
- Pre-assembled bearings with optimal preload settings minimize maintenance requirements.
- Sealing & Lubrication:
- Triple-lip seals retain high-viscosity gear oil (e.g., GL-5 85W-140) for extended bearing life.
- Drain and fill plugs for easy lubricant maintenance.
- Easy Installation & Maintenance:
- Direct OEM replacement for part number T38A0, ensuring seamless fitment.
- Modular design allows for quick bearing replacement without disassembling the entire hub.
