Machine Description
Spring Fatigue Testing Machine is a high-
performance, precision-engineered system
designed to evaluate the endurance and
lifespan of compression, tension, and torsion
springs under repetitive cyclic loading. This
machine simulates real-world stress conditions
by subjecting springs to controlled, high-speed
cyclic loads over extended periods—making it
essential for automotive, aerospace, railway,
and industrial spring manufacturers focused
on quality assurance and durability testing.
Features
• Suitable for compression, tension, and torsion springs
• High-speed cyclic loading for accelerated fatigue testing
• Adjustable stroke length, load, and test frequency
• Test capacity from light-duty springs to heavy industrial types
• Cycle counter with failure detection and auto-stop function
• Digital display or PLC+HMI interface for test monitoring
• Rugged frame for vibration-free long-duration operation
• Safety enclosure and overload protection
• Customizable fixtures for various spring sizes and types
