Servohydraulic Testing Actuators

Servo-hydraulic testing actuators are used in materials and component testing to reproduce precise, pre-determined forces and travel. They cope equally well with periodic or random signals and with loadings ranging from static to continuous. These actuators can be integrated into a load frame (Models HA, HB, HC) or used as a single testing actuator on a platform.

• Available in various versions for test loads from 5 to 2500 kN.
• Standard testing actuator stroke is 40, 100, 250 or 400 mm. 
• System design pressure of 210 or 280 bar. 
• Robust, fatigue-resistant design. 
• Double-end rod cylinder with equal piston surface area for tension and compression.
• Hydrostatic piston rod bearing guarantees quasi-frictionless operation and  high transverse force absorption.
• Hydraulic end-position damping allows high piston speeds.
• Integrated displacement transducer. 
• Top or bottom-mounting.
