The hydraulic power unit in the NG-SHM Class DP – Servo Hydraulic Testing Machine is engineered to maintain excellent axial alignment, which avoids lateral loading during testing operations. Axial alignment ensures that the force applied through the hydraulic system is directed precisely along the intended vertical axis of the specimen. This precise alignment reduces side forces that can cause bending, uneven stress distribution, or inaccurate test results.

Avoiding lateral loading protects the specimen from unintended deformation but also reduces wear on internal components such as seals and pistons. It ensures smooth actuator movement and consistent force delivery, both of which are vital for generating accurate and repeatable results. This alignment also contributes to the equipment’s longevity, as it minimizes stress on mechanical parts.
