About the system
Servo-hydraulic linear actuators are the core force-generating element of road simulators, fatigue benches and custom test systems. The polymer-bearing series covers 15–1000 kN, while the low-friction hydrostatic-bearing series handles high-speed dynamic applications up to 3.6 m/s. They are supplied with integrated LVDT, servo valve and manifold, and long-stroke, swinging and heavy-duty versions are available.
Technical scope
- 15–1000 kN
- Stroke up to 400 mm; long-stroke variants
- Up to 3.6 m/s
- High-speed, swinging and heavy-duty cylinders
