STEP Lab's test systems based on high-performance electromechanical actuators offer outstanding flexibility, making them ideal for both static and dynamic testing, and especially well suited to fatigue testing applications. Covering a load range from 200 N to 268 kN, these machines offer a wide choice of speeds, high-quality load frames and intelligent drive systems.
Certified to ISO, EN and ASTM standards, these electromechanical machines guarantee high performance through advanced measurement and control systems. Far more than simple electromechanical actuators, they are genuine electric machines for any application requiring high performance: used in material test laboratories, product quality certification laboratories, and for repetitive testing on the production line, even in 24/7 applications.
- Five models: EA025 / EA050 / EA100 / EA200 — dynamic force range from 20 kN to 200 kN (EA05 available on request for special applications)
- Designed for dynamic and fatigue testing across billions of cycles
- Improved actuator size-to-force ratio
- Can operate in single- or multi-actuator mode
- Maintenance-free, low energy consumption, easy installation
- EA025 — next-generation actuator alternative to hydraulic systems, with 25 kN dynamic capacity, 1600 mm/s test speed and 30 Hz frequency
EA025 — New Electric Actuator
The new 'EA025' actuator is designed to replace hydraulic systems: it offers high performance, low maintenance cost and durability across billions of cycles. With a dynamic load capacity of up to 25 kN, a 1600 mm/s test speed and 30 Hz frequency, it is ideal for material testing, fatigue testing and static testing. A wide range of accessories — extensometers, climate chambers, torsion actuators and grips — lets it be adapted to any test need.

Use Cases
| Area | Description |
|---|---|
| Material test laboratories | Used together with standard test setups and the Test Center controller and software to build highly reliable, flexible test machines for the static and dynamic characterization of any material. |
| Quality certification laboratories | Together with the Test Center controller and software, complex product tests can be run standalone or mounted alongside other actuators on frames built by Steplab or the customer. |
| Production line | For press-fit or quality-control purposes; the combination of advanced control, dedicated QC software and high-precision mechanical components makes it ideal for repetitive high-cycle testing, even in 24/7 applications. |
