Product overview Linear actuators Electromechanical linear actuators enable precise, controlled, and repeatable push/pull movements in linear drive applications. Linear actuators serve as efficient, virtually maintenancefree, and environmentally friendly alternatives to hydraulic or pneumatic types. Actuators with a modular design and open architecture offer opportunities to choose and integrate components to achieve customized solutions within existing envelopes. Application potential expands with the introduction of technologies for specific purposes, such as hall sensors, limit switches, potentiometers,...

Lifting columns enable precise, controlled, and repeatable lifting movements of in linear drive applications including with those with torsion and off set loads. Lifting columns with a modular design and open architecture offer opportunities to choose and integrate components like linear actuators or drive to achieve customized solutions within existing aluminum profiles. Application potential expands with the introduction of technologies for specific pur- poses, such as hall sensors, limit switches but also Integrated Circuits for switch mode power supply and motor control. Equipped with brushes...

Lead screw Screws Ball and roller screws are key components to build electric cylinders. They transfer rotary movements of the motor into linear movements. Their efficiency and their load and speed capabilities have a very big influence on the performance of electric cylinders. Thanks to decades of experience with manufacturing ball and roller screws and continuous product and process development, Ewellix builds electric cylinders with precision screw solutions that fulfill the most demanding applications in terms of efficiency, precision, durability and value. All screws are made of high-strength...
