Ball Joint Durability Test Rig – Multi-Axis Servo-Hydraulic Test System for Automotive Suspension Components
The Ball Joint Durability Test Rig is a specialized, high-performance testing platform engineered for evaluating the fatigue life, durability, and functional behavior of automotive ball joints under real-world conditions. Designed to support SAE J193 test standards, the rig simulates axial and radial loads experienced during actual driving cycles.
Capable of applying up to 100 kN axial and 50 kN radial loads, the system features servo-hydraulic actuators, precision control, and multi-axis synchronous loading to replicate complex motion patterns and road-induced stress. For advanced testing, the rig can integrate environmental chambers to perform temperature and humidity simulation during test cycles. It is optimized for long-term endurance testing, allowing automated control over millions of load repetitions.
