Product Descreiption
The Dongfeng Truck Bearing Series is a premium line of high-performance bearings engineered to meet the demanding requirements of Dongfeng’s commercial vehicles, including heavy-duty trucks, buses, and special-purpose vehicles. Designed for critical applications such as wheel hubs, steering systems, transmissions, and engines, these bearings ensure smooth operation, reduced friction, and extended service life under extreme loads, high speeds, and harsh environmental conditions. Manufactured to Dongfeng’s OEM specifications, this series combines advanced materials, precision engineering, and robust design to deliver unmatched reliability.
Key Applications
- Vehicle Systems:
- Wheel Hubs & Axles: Supporting radial and axial loads in front and rear axles.
- Steering Systems: Reducing friction in steering knuckles and tie-rod ends.
- Transmissions & Differentials: Enabling efficient power transfer in gearboxes and drive shafts.
- Engine Components: Supporting crankshafts, camshafts, and water pumps.
- Compatible Dongfeng Models:
- EQ140, EQ145, EQ153, EQ1168, EQ1250, EQ2102, and other medium- to heavy-duty trucks.
- Industrial Use:
- Fleet maintenance, aftermarket upgrades, and industrial machinery applications.
Technical Specifications
- Bearing Types:
- Tapered Roller Bearings: For high radial and axial loads (e.g., wheel hubs).
- Deep Groove Ball Bearings: For low-friction, high-speed applications (e.g., engine accessories).
- Cylindrical Roller Bearings: For heavy radial loads (e.g., transmission gearboxes).
- Spherical Roller Bearings: For misalignment tolerance (e.g., suspension systems).
- Needle Roller Bearings: For compact spaces (e.g., steering systems).
- Materials & Coatings:
- Inner & Outer Rings:
- High-Carbon Chromium Steel (GCr15 or equivalent): Hardened to 60–65 HRC for wear resistance.
- Rolling Elements:
- Case-Hardened Steel for durability.
