Key Applications
- Dongfeng EQ153 Series Trucks: Including cargo trucks, dump trucks, tankers, and special-purpose vehicles.
- Compatible Models: Dongfeng EQ145, EQ153, EQ1141, and similar chassis variants.
- Industrial Use: Construction fleets, mining logistics, municipal service vehicles, and agricultural machinery conversions.
Technical Specifications
- Material & Construction:
- Primary Material: High-strength forged alloy steel (40Cr or equivalent) for superior tensile strength and fatigue resistance.
- Surface Treatment:
- Hot-dip galvanizing for corrosion resistance in harsh environments.
- Shot peening to enhance surface hardness and reduce stress cracking.
- Heat Treatment: Quenched and tempered to achieve Rockwell hardness (HRC) 28–35 for optimal wear resistance.
- Key Dimensions (Example: Dongfeng 153 Standard Variant):
- Overall Height: ~320–350 mm (12.6–13.8 inches).
- Kingpin Bore Diameter: ~60–65 mm (2.36–2.56 inches).
- Wheel Hub Mounting Diameter: ~180–200 mm (7.09–7.87 inches).
- Weight: ~12–15 kg (26.5–33.1 lbs).

- Brake Caliper Bracket: Welded or bolt-on design for compatibility with drum or disc brake systems.
- Load & Performance Ratings:
- Maximum Vertical Load: ~8–10 tons (depending on truck configuration).
- Operating Temperature Range: -40°C to +120°C (-40°F to +248°F).
- Fatigue Life: >500,000 cycles under full load (tested per ISO 16750-3 standards).
Key Features
- Enhanced Durability:
- Forged steel construction resists cracking and deformation under heavy loads and off-road impacts.
- Corrosion-resistant coatings extend service life in salt, mud, and chemical exposure.
- Precision Steering Control:
- Tight tolerances in kingpin and ball joint mounting ensure minimal play and smooth steering response.
- Compatible with OEM steering systems for seamless integration.
- Easy Installation & Maintenance:
- Direct OEM replacement for part numbers DF-153-SK-XXXX (refer to vehicle manuals for exact references).
- Modular design allows quick replacement without disassembling the entire steering system.
