1. This tester is a new generation of fatigue testing machine, specially designed for low cycle and high cycle fatigue testing of spring & bellows.
2. The computer controlled electro-hydraulic servo bellows fatigue testing machine is mainly used in large-scale precision spiral spring, disk spring, annular corrugated hose, widely used in flexible piping enterprises and spring factories.
3. Electro-hydraulic servo bellows fatigue testing machine consisted of one set host ( overhead type 50KN servo linear actuator ), constant pressure servo pump station ( flow 40L/min, system pressure 21MPa),hydraulic chuck, hydraulic drive module, full digital single channel servo controller, computer and printer.
