Passenger Car Axle Half-shaft

The Passenger car axle half-shaft is the most critical torque-transmitting part in a vehicle's drivetrain. It must survive acceleration, bumps, and heavy loads without ever snapping. At Kangding Machinery, we manufacture each Passenger car axle half-shaft using premium 40Cr or 42CrMo alloy steel, forged and heat-treated in our 27,000sqm workshop. Since 2011, we've focused on "High-Quality Supplier" standards, ensuring our shafts deliver a nominal torque capacity up to 8000N·m. Our shafts are built to provide a stable, vibration-free ride for the most demanding passenger car applications.

Precision splining is what makes our Passenger car axle half-shaft superior. We use our 200+ wire-cutting machines and 40+ CNC units to ensure that every spline meets IT6-IT7 grade accuracy. This guarantees a perfect fit with the differential and the wheel hub, eliminating backlash and operational noise. Every shaft is balanced to perfection and protected with a blacking or phosphating finish to resist corrosion. We understand that on the road, safety is paramount; that's why we perform 100% inspections on the heat-treated hardness and dimensions to ensure your fleet stays rolling safely.
