Electric Cylinder Actuator Components And Materials Guide

The working principle of electric cylinder actuator is that it integrates a motor and a travelling nut screw jack, converting rotation of the motor shaft into linear motion of the piston rod of the electric linear actuator. We provide the high quality materials that meets the international standards, typically produce the best-performing electric cylinders.

Below is a summary of the various materials used in electric cylinders construction.
