DY Series Electro Hydraulic Servo Testing System – Precision Fatigue Testing Solution
SINOTEST DY series electro hydraulic servo testing system is specially designed for tensile, compression, bending, and shear tests of high-strength materials. Specifically, this electro hydraulic servo fatigue testing system can meet the mechanical testing needs of multiple fields—from complex thermo-mechanical fatigue research to standard tension or compression fatigue tests. As a result, it provides accurate and reproducible test results across a wide range of applications.
Furthermore, the DY series system adopts SINOTEST’s self-produced MCT PL series hydrostatic bearing actuator. Consequently, it greatly extends its service life compared to traditional chrome-plated sealing actuators, ensuring long-term reliability and consistent performance. Our quality management system is certified to ISO 9001:2015, guaranteeing manufacturing excellence.
