Product Descreiption
The Dongfeng Truck K37M0 Front Wheel Hub is a critical component designed for the front axle assembly of Dongfeng’s medium- and heavy-duty commercial vehicles. Engineered to deliver exceptional strength, durability, and reliability, this wheel hub ensures smooth wheel rotation, precise steering control, and load-bearing stability under demanding operating conditions. Ideal for trucks, buses, construction machinery, and municipal vehicles, the K37M0 front wheel hub combines advanced materials and precision manufacturing to meet the rigorous demands of modern logistics, transportation, and industrial applications.
Key Specifications
- Application Compatibility:
- Vehicle Models: Fits Dongfeng’s DFL, DFH, Tianlong, KR, and other series trucks (e.g., 4×2, 6×4, and 8×4 configurations), including cargo trucks, dump trucks, tractors, and specialized vehicles (e.g., fire trucks, garbage trucks).
- Axle Type: Designed for Dongfeng’s front steering axles (e.g., 5-ton or 7-ton capacity), commonly used in medium-duty to heavy-haul applications.
- Material & Construction:
- Hub Body: High-strength nodular cast iron (e.g., QT450-10) or forged alloy steel for superior load-bearing capacity and impact resistance.
- Bearings: Double-row tapered roller bearings (e.g., 32200 series) pre-lubricated with high-temperature grease for smooth operation and extended service life.
- Seals: Heavy-duty rubber or metal-clad seals to prevent contamination from dust, water, and debris.
- Dimensions:
- Outer Diameter: ~220–240 mm (8.66–9.45 inches) (varies by configuration).
- Bolt Circle Diameter (PCD): 10 x 225 mm (10-bolt pattern, 225 mm pitch circle diameter) or 8 x 220 mm (customizable for specific models).
- Center Bore: ~120–130 mm (4.72–5.12 inches).
- Hub Width: ~150–170 mm (5.91–6.69 inches).
- Weight: ~18–22 kg (39.7–48.5 lbs) (depending on material and design).
- Load Rating:
- Static Load Capacity: Up to 7,000 kg (15,432 lbs) per hub (designed for GAWR ≤14,000 kg front axles).
- Dynamic Load Rating: Compliant with ISO 28580:2018 standards for commercial vehicle wheel hubs.
- 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
- High Load-Bearing Capacity:
- Reinforced design with optimized rib patterns to distribute stress evenly and prevent deformation under heavy loads.
- Suitable for applications with frequent starts/stops, uneven terrain, or overloading risks.
- Enhanced Durability:
- Corrosion-resistant coatings (e.g., zinc plating or epoxy paint) 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.
- Precision Engineering:
- Tight tolerances (≤0.02 mm runout) ensure smooth wheel rotation and reduced vibration.
- Compatible with ABS (Anti-lock Braking System) sensors for improved safety and braking performance.
- 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.
