Designed for robust drivetrain performance, our Chery Drive Shafts deliver reliable torque transfer in demanding conditions. Crafted from 42CrMo high-strength alloy steel (ASTM A1084, tensile strength ≥1,200 MPa), they undergo precision machining (±0.05mm tolerance) and dynamic balancing (ISO 1940 G2.5 class) to minimize vibration at speeds up to 12,000 RPM. Validated via SAE J2521 fatigue testing (1 million+ stress cycles), they resist deformation under heavy loads. Zinc-nickel plated (ASTM B117) for corrosion resistance, paired with IATF 16949 certification, these shafts ensure 150,000+ km service life – a 20% upgrade over standard aftermarket alternatives.
Forged from 42CrMo high-strength alloy steel (ASTM A1084, tensile strength ≥1,200 MPa), our drive shafts undergo a dual heat treatment: core quenching to HRC 58+ (vs. industry avg. HRC 54) for wear resistance, and surface induction hardening to 52 HRC for impact toughness. This reduces spline wear by 35% under 10,000 N·m torque (ASTM D5656 tested), extending service life to 150,000+ km – 25% longer than generic aftermarket shafts.
Machined to ±0.03mm tolerance (tighter than ISO 1940 G3.0 standards), our shafts feature splines, journals, and couplings with roundness ≤0.005mm. Paired with dynamic balancing to G2.5 class (ISO 1940), vibration at 12,000 RPM is reduced by 28% vs. unbalanced shafts (tested via laser vibrometer). This ensures smooth drivetrain operation and lowers noise to ≤62dB at 100km/h – critical for driver comfort.
Validated via 1 million+ stress cycles (SAE J2521), our shafts resist cracking or deformation under repeated heavy loads (e.g., towing, off-roading). Salt-spray testing (ASTM B117) confirms 500+ hours of corrosion resistance, even in coastal or winter conditions (road salt exposure). Field data from 500+ commercial fleets shows 99% survival rate after 2 years of daily use.
Designed with a universal profile (spline count: 24-32, diameter: 25-35mm, length: 600-1,200mm), our shafts match 95% of mainstream vehicle driveline specs (non-OEM-specific). Pre-machined splines and pre-lubricated U-joints reduce installation time to ≤20 minutes (vs. 45+ minutes for OEM-specific parts, per 30+ repair shop trials), cutting labor costs for installers.

Here are specific application scenarios of drive shaft:
Ideal for urban vehicles with frequent starts/stops, our drive shafts minimize vibration by 28% (ISO 1940 G2.5 balanced) and reduce noise to ≤62dB at 80km/h (laser vibrometer tested). This ensures driver comfort even after 50,000+ km of daily commuting, validated by 3rd-party simulations of typical city routes (e.g., 30 accelerations/decelerations per hour).
Designed for delivery trucks and cargo vehicles, the shafts handle dynamic torques up to 10,000 N·m (SAE J2521) and static loads of 15,000 N. Field tests with 50+ logistics fleets show 99% survival rate after 12 months of 10-hour/day, 5-day/week use (100,000+ km), outperforming generic shafts by 30% in fatigue resistance.
Suited for cold winters or coastal regions, the shafts operate reliably from -40℃ to +150℃ (ASTM D2306) and resist salt spray for 500+ hours (ASTM B117). Thermal imaging confirms no thermal expansion issues at 120km/h, critical for de-iced roads or desert routes.
Built for towing, farming, or off-road vehicles, the shafts resist torque spikes up to 12,000 N·m (SAE J2521) and absorb 30% more impact energy than industry averages (impact test per ASTM E23). This prevents cracking during sharp turns or heavy loads (e.g., trailer towing).
With a universal design (spline count: 24-32, diameter: 25-35mm), our shafts match 95% of mainstream driveline specs (non-OEM-specific). Installers report 30% faster replacement vs. OEM parts (50+ repair shop trials), reducing labor costs and inventory complexity for wholesalers.
Clean the hub and shaft interfaces with isopropyl alcohol (remove debris/oil); inspect splines for wear (replace if >0.1mm damage, per SAE J533). Ensure shaft length matches driveline specs (tolerance: ±1mm).
Use a calibrated torque wrench (±3% accuracy). Tighten mounting bolts in a star pattern to 95-115 N·m (final recheck after 50km: 105-125 N·m, ISO 16130).
Apply 30-40g of NLGI 2 lithium-complex grease (ASTM D2265) to splines/joints (avoid overfilling – excess causes heat buildup).
Drive 50km at ≤80km/h initially. Check for noise (>62dB indicates misalignment) or vibration (accelerometer >0.5g requires re-torque).
