Backed by 15+ years of automotive driveline expertise, our drive shafts are engineered to meet Chery’s original specifications, ensuring seamless integration with its propulsion systems. Crafted from high-strength 42CrMo alloy steel, each unit undergoes precision cold-forging and 200-hour heat treatment, achieving an anti-torsion strength of 1,200MPa—critical for maintaining power transfer efficiency under heavy loads.
Certified to ISO/TS 16949 (automotive quality management), we validate durability via 2-million-cycle fatigue testing and salt-spray corrosion resistance checks (500hrs). Designed for low-vibration operation, our shafts reduce driveline noise by 15% compared to generic aftermarket alternatives, extending component lifespan by 30%.
Trusted by global Chery repair networks, we combine technical precision with rigorous validation to deliver reliable, long-term performance.
With 15+ years of automotive driveline R&D experience, our drive shafts are crafted to match Chery’s original design parameters with ±0.05mm dimensional tolerance—ensuring plug-and-play installation without modifications. Leveraging CNC machining centers and robotic assembly lines, we achieve consistent part-to-part precision, reducing fitment errors by 92% compared to generic aftermarket alternatives. This engineering rigor makes our shafts the preferred choice for 500+ global Chery repair networks, where "no rework" is non-negotiable.
Constructed from 42CrMo alloy steel (a material certified for automotive driveline applications), each shaft undergoes 200-hour vacuum heat treatment and shot peening, elevating its anti-torsion strength to 1,200MPa—25% higher than industry-standard 35# steel. This ensures it withstands torque spikes up to 8,000N·m (common in Chery’s turbocharged models) without deformation. Independent lab tests confirm a service life exceeding 150,000 km under heavy-duty conditions, making it ideal for commercial fleets or high-mileage users.
Backed by ISO/TS 16949 certification (the gold standard for automotive components), our production line adheres to strict process controls—from raw material inspection (100% chemical composition testing) to final validation. Each shaft is subjected to:
2-million-cycle fatigue testing (simulating 10 years of daily use) to guarantee no cracks;
500-hour salt-spray corrosion test (exceeding marine-grade requirements) for coastal regions;
Dynamic balance calibration (G1.0 precision) to minimize vibration.
These protocols have earned us trust from 30+ international aftermarket distributors, who prioritize "test-proven reliability" over low-cost alternatives.
Unlike generic shafts that often introduce 8-12dB of driveline noise, our products feature helical gear teeth and optimized weight distribution, reducing vibration by 15% (tested at 60km/h). This not only enhances driver comfort but also extends the lifespan of connected components (e.g., differential gears) by 30%, as validated by SGS tribology reports. For fleet operators, this translates to lower maintenance costs—an average $200/year saved per vehicle.
| Parameter Category | Specification | Significance |
| Material | 42CrMo alloy steel (ASTM A1021 Grade 42CrMo4) | High-strength, low-alloy steel optimized for torsional fatigue resistance; widely used in automotive drivelines per SAE standards. |
| Manufacturing Process | CNC cold forging → Robotic welding (MIG) → 200hr vacuum heat treatment → Shot peening → Dynamic balancing | Cold forging preserves grain structure (enhancing strength); vacuum heat treatment eliminates surface decarburization; shot peening reduces surface stress (extending fatigue life). |
| Dimensional Tolerance | ±0.05mm (critical dimensions: journal diameter, spline pitch, overall length) | Ensures plug-and-play compatibility with Chery’s original driveline components; exceeds ISO 2768-mK (general engineering tolerance class). |
| Mechanical Strength | - Tensile strength: ≥1,200MPa - Yield strength: ≥1,000MPa - Torsional strength: ≥800MPa | Withstands peak torque up to 8,000N·m (common in commercial/light truck applications); 25% higher than industry-standard 35# steel. |
| Fatigue Resistance | 2,000,000+ cycles (ASTM E466-17 standard) | Simulates 10+ years of daily use (50km/day, 5 days/week); validated via servo-hydraulic testing machine. |
| Corrosion Resistance | 500hr salt-spray test (ASTM B117) → Rating: 9 (no visible rust; pitting ≤0.1mm) | Exceeds marine-grade requirements (typically 300hr); suitable for coastal regions or high-humidity environments. |
| Dynamic Balance | G1.0 precision (ISO 1940-1:2016) | Reduces driveline vibration by 15% at 60km/h (vs. G2.5 generic parts); minimizes wear on differential/gearbox. |
| Certifications | ISO/TS 16949:2016 (automotive quality management) SGS Material Compliance Report | Certified for use in automotive OEM/aftermarket supply chains; guarantees consistent process control. |
Here are specific application scenarios of drive shaft:
Designed for daily urban use, our drive shaft excels in scenarios with frequent acceleration/braking (e.g., taxi fleets, delivery vehicles). Its 42CrMo alloy steel construction absorbs 30% more torsional shock than standard 35# steel, reducing wear during stop-and-go traffic. Validated via 100,000 start-stop cycles (simulating 5 years of urban commuting), it maintains <0.1mm backlash in spline connections—ensuring consistent power transfer without costly repairs.
Ideal for intercity logistics, our shafts endure extended high-load driving (e.g., 8-hour daily routes with 5-ton cargo). With a 2,000,000-cycle fatigue resistance (ASTM E466-17), they withstand 150,000+ km of continuous use—outperforming generic aftermarket parts by 40% in lifespan. This reduces downtime for fleet operators, cutting annual maintenance costs by ~$1,500 per vehicle.
For regions with high humidity, salt exposure, or occasional rain (e.g., port logistics, island delivery), our drive shaft’s 500-hour salt-spray resistance (ASTM B117) prevents surface rust and internal pitting. Independent SGS tests confirm 9/10 corrosion resistance rating—ensuring reliable performance even after 3 years of coastal use, where standard shafts fail within 18 months.
Trusted by 300+ independent repair shops, our drive shafts serve as OE replacements for light commercial vehicles (e.g., small trucks, utility vans). With ISO/TS 16949 certification and ±0.05mm dimensional precision, they eliminate fitment issues—enabling workshops to complete repairs in 1.5 hours (vs. 3+ hours for ill-fitting generic parts), boosting customer satisfaction and turnover.
Verify dimensional alignment with original equipment specs using a caliper (tolerance: ±0.05mm). Clean contact surfaces with ISO 46 hydraulic oil to remove debris—prevents 90% of fitment errors (based on 10,000+ installation cases).
Secure splines with a calibrated torque wrench (120-150N·m per SAE J2971). Over-tightening risks shaft deformation; under-tightening causes vibration—our R&D team validated this range for 500,000+ load cycles.
Run the driveline at 30-60km/h (20-35mph) for 5 minutes, then measure vibration with a laser tachometer. Optimal vibration amplitude: ≤0.5mm/s (G1.0 balance per ISO 1940). Adjust mounting bolts if exceeding limits.
Lubricate universal joints every 5,000km (3,100 miles) with SAE 75W-90 gear oil. Inspect for corrosion/pitting monthly—if pitting exceeds 0.1mm depth, replace immediately (per ASTM A1021 standards).
