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 maintenance-free, 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,...

Lead screw Precision rolled ball screws Roller screws Precision rolled ball screws Roller 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...

Product range comparison Force and speed capabilities The graph below (⮑ diagram 1) provides a quick overview about the continuous force, peak load capabilities and the speed of the high performance actuators with servo motors. Use this graph to quickly evaluate which actuator could fit best in your application. The continuous force describes the force the actuator can push or pull continuously without overheating. The peak load is the maximum force an actuator can push or pull for a short time (peak) at low speed, without being mechanically destroyed or by overheating. The vmax is the maximum...
