How Electric Rod Actuators Work

Electric rod actuators, also known as electric linear actuators, operate by converting electrical energy into linear motion through a motor-driven mechanism — typically a ball or planetary roller screw — translating rotational motion into precise and controlled linear displacement.

The Benefits of Using
Electric Rod Actuators 

Electric rod actuators are often preferred over other options due to their precise and efficient linear motion capabilities, offering enhanced control and flexibility in various applications.

  • Clean and Energy Efficient. With electric rod actuators there are no air leaks from pneumatics and no oil leaks from hydraulics. Electric linear motion eliminates risk of leaks that are inherent to fluid power systems.
  • Continuous, High Duty Cycle Performance. Provides 24 x 7 reliability for high duty cycle applications. Tolomatic’s Endurance Technology™ designs are built to last. Need high force capabilities? Take a closer look at the RSX family of actuators.
  • Control to Get The Job Done Right. Tolomatic electric rod actuators provide adjustable, precise linear motion for improved efficiency, quality and yield in applications.
