EWELLIX A Schaeffler Company Linear solutions for spot welding Compact, robust, and modular solutions Electrical actuators in automated lines help to enhance the welding assembly process by being reliable and programmable. Automotive manufacturers strategically work on vehicle weight reduction to meet regulatory and market demands. New high-strength materials demand consistent, high-quality joints. Servo actuators offer efficient and reliable welding processes to follow market trends. Ewellix electromechanical actuators are more reliable and energy efficient than the old-style pneumatic versions. They combine a best-inclass roller screw mechanism powered by a brushless servomotor and offer great benefits. Ewellix mechatronic solutions integrated into assembly lines offer: • Reliability • Consistency in the welding process • Minimal maintenance • Reduced downtime • Improved total cost of ownership Besides improvements and the evolution of the vehicle itself, companies are actively looking for a more diverse, flexible, and reduced assembly line footprint that will positively impact the environment. Ewellix has a long-standing tradition of technical expertise. We support customers in improving automotive manufacturing equipment for joining and welding processes that run faster, longer, and safer sustainably. Planetary roller screw technology benefits • Power density • Robustness • Long service life • Efficiency and energy reduction

Linear solutions for spot welding Ewellix core technology for assembly automation Ewellix is a pioneer in the technology of roller screws and offers high quality, high performance and the most comprehensive assortment of roller screws available on the market. In addition, planetary technology helps improve screw performances following market needs in power density. 6 Ball screw Roller screw *On an equivalent screw diameter Comparison of ball screws and roller screws performances Application examples X welding gun frame Function • Electrical actuators actuate both gun arms as a scissor mechanism...

Linear solutions for spot welding Ewellix CEMC modularity Water cooling option Following increased market productivity needs, the optional water-cooling system allows water to circulate the motor stator, reducing the actuator's running temperature while operating higher duty cycles. When the actuator has to self-move without any other guidance to complete its function, the Ewellix integrated anti-rotation device is the ideal solution. The robust, no-play embedded system prevents push rod from rotating with minimal maintenance needs (over actuator lifetime). Water inlet Water outlet • Consistent...
