The NG-SHM Class DP – Servo Hydraulic Testing Machine features a piston and piston rod constructed as a one-body forging, which provides superior structural strength and impact resistance. This one-piece design removes connection points prone to stress and wear in multi-part assemblies. As a result, the system benefits from more reliable force transmission, reduced mechanical failure risk, and enhanced durability during repeated testing under high loads.

Additionally, the piston is equipped with a high-performance sealing ring capable of withstanding pressures up to 70 MPa. This robust seal prevents hydraulic fluid leakage even under extreme operating conditions, maintaining pressure integrity throughout each test. The combination of one-body forging and high-pressure sealing guarantees that the hydraulic system functions with precision, delivering accurate test forces while maintaining long-term reliability.
