Product Descreiption
The 2502ZAC940B Basin Gear is a high-performance crown wheel (ring gear) designed for heavy-duty commercial vehicle differential systems. Engineered to withstand extreme torque, load, and operational stress, this component is a critical part of the rear axle assembly, ensuring smooth power transmission, traction, and durability in demanding applications. Ideal for trucks, buses, construction machinery, and agricultural vehicles, the 2502ZAC940B basin gear combines precision manufacturing with robust materials to deliver reliability and longevity.
Key Specifications
- Application Compatibility:
- Vehicle Types: Fits heavy-duty trucks (e.g., 6×4, 8×4), buses, dump trucks, tractors, and construction equipment.
- Axle Models: Compatible with axle brands such as Dongfeng, FAW, Sinotruk (Howo), and other aftermarket heavy-duty axle systems (e.g., HY160, AC16, or equivalent).
- Gear Ratio:
- Standard Ratio: 4.875:1 (optimized for balanced torque and speed in mixed-use scenarios).
- Optional Ratios: 4.11:1 (high-speed applications), 5.143:1 (enhanced low-end torque), or 5.833:1 (heavy-haul or off-road use).
- Material & Construction:
- Gear Material: High-strength alloy steel (e.g., 20CrMnMo or 22CrMoH) with carburizing and quenching for superior hardness and wear resistance.
- Tooth Profile: Spiral bevel gear design for reduced noise, vibration, and improved load distribution.
- Surface Treatment: Nitriding, shot peening, and anti-corrosion coatings for extended service life.
- Dimensions:
- Outer Diameter: ~320–350 mm (12.6–13.8 inches) (varies by ratio and customization).
- Module: 8–9.5 (metric sizing).
- Face Width: 45–52 mm (1.77–2.05 inches).
- Weight: ~15–18 kg (33–39.7 lbs) (depending on configuration).
- Torque Capacity:
- Maximum Input Torque: Up to 5,000 N·m (3,688 lb·ft) (suitable for engines up to 500 hp).
- Load Rating: Designed for GAWR (Gross Axle Weight Rating) of 13,000–16,000 kg (28,660–35,274 lbs).
- Lubrication:

- Oil Capacity: ~3.0–3.5 liters (0.79–0.92 gallons) for the differential housing.
Technical Features
- High-Strength Power Transmission:
- Optimized tooth geometry minimizes friction and energy loss, improving fuel efficiency by up to 3–4% in heavy-load conditions.
- Helical gear design reduces noise levels to ≤82 dB under full load, enhancing operator comfort.
- Enhanced Durability:
- Heat-treated gears resist pitting, scoring, and fatigue in high-stress applications.
- Corrosion-resistant coatings extend service life in harsh environments (e.g., dust, mud, salt, or extreme temperatures).
- Interchangeability & Customization:
- Direct replacement for OEM part numbers (e.g., 2502ZAC940B or equivalent aftermarket codes).
- Customizable gear ratios and dimensions to fit specific axle or vehicle requirements.
- Easy Maintenance:
- Modular design allows for quick disassembly and inspection.
- Adjustable backlash settings ensure precise gear alignment and longevity.
