1.Product Description
The automotive high-reliability double universal joint shaft is made of high-strength alloy steel and precision manufacturing processes, designed for demanding applications such as mining vehicles and special-purpose vehicles. With its double cross-joint + reinforced half-shaft structure, it can withstand 11,000 N·m continuous torque and 20,000 N·m instantaneous impact torque while maintaining exceptional performance in high-temperature, high-humidity, and high-dust environments. With a failure rate below 0.01%, it is the ultimate replacement for traditional driveshafts.
