Rodless Electro-Mechanical Actuators
Precise, Efficient Electric Motion for Space-Constrained Automation
Tolomatic rodless electro-mechanical actuators provide programmable linear motion for automated equipment where precise positioning, flexible speed control, and efficient operation are important. Available in both screw-driven and belt-driven designs, these electric linear actuators offer a range of bearing styles and configurations to accommodate different loads, speeds, stroke lengths, and application requirements.
Unlike pneumatic actuators, which depend on compressed air, electric actuators use motor-driven motion for precise and programmable control. The rodless design keeps the moving load within the actuator’s overall profile, helping conserve machine space while supporting long strokes and flexible machine layouts. Depending on the actuator design, applications can benefit from accurate positioning, adjustable speed and acceleration, repeatable motion, and reduced dependence on compressed air.
Rodless electro-mechanical actuators are well suited for material handling, pick-and-place, packaging, assembly, machine automation, and other applications requiring controlled linear motion.
