LINEAR ACTUATORS – SERIES

At STEP Lab, we have designed three series of testing machines based on electric linear actuators:

UD Series: ideal for continuous dynamic testing with millions of cycles.
HUD Series: suitable for endurance testing due to high dynamic forces.
XUD Series: dedicated to short-term tests with higher accelerations.

These machines, all based on linear actuators, follow our tradition and consequently offer all the distinctive advantages of electrical technologies.

Features of STEP Lab systems

Closed-loop force and displacement control via Test Center controller
High-resolution data acquisition in 24bit
Can be installed on any type of structure
Up to 8 controlled and synchronised axes
Control station in separate and independent position
Simple and flexible test management via a graphical Test Center interface
Wide variety of grips, dedicated test accessories, and load cells
Integration with extensometers and climatic chambers
Wide operating range, manageable speeds from 0.01mm/s up to 2,000mm/s, and high stroke of 100mm

FEATURES

No maintenance

High reliability

High efficiency

Wide range of use
