Servo actuator
* Maximum stroke: ±75mm (total stroke 150mm);
* Special dynamic servo actuator for dynamic and static test;
* Double-out rod, the surface of the piston rod is treated with special technology, and special technology is adopted for
high-quality finish treatment, which is suitable for long-term dynamic test;
* The high-speed sealing element (German Trelleborg Servo Glyd ring, Sterling) is used to seal between the piston and the
cylinder body, the piston rod and the end cover. And choose high-speed wear-resistant support ring (German Trelleborg) support, which makes the actuator rigid,
* Strong anti-direction finding ability;
* The actuator has built-in displacement sensor, external electro-hydraulic servo valve and force sensor, with two closed-loop control loops of force and displacement;
* The force sensor is placed on the head of the piston rod, and the prestressing ring is installed and configured, which can
fully ensure the safety and reliability of the connection during the dynamic test;
