Why is Rotary Actuator Important in Robotics Manufacturing?

Robots defy the meaning of technology. It gives us so many benefits related to work and improves the performance of manufacturing industries. Factories that utilize robotic automation integrate industrial machinery such as welding, assembly, and rotary actuator. In this article, we are going to discuss the importance of the rotary actuator and the application towards manufacturing industries.  To learn more about the rotary actuator, visit InteLiDrives

Importance of Robot Automation in Manufacturing Industry

By implementing the automation system in manufacturing, it will give many advantages, including:

  • Saves money
  • Enhanced labor production
  • Reduce cycle time
  • Space saver
  • Produce high-quality parts
  • Reduce waste disposal and
  • Lower production cost

Rotary Actuator

The rotary actuator is a device that converts energy in the form of rotation. The force was being applied from a distance away to its origin of rotation, which causes a turning movement.

Rotary actuators can be used either manually, electrical, or hydraulic powered devices.

  1. Manual Rotary Actuators

Manual rotary actuators referred to as “gear operators” in the valve industry, these actuators often use large handwheels to enhance the application of torque further.

  1. Electric Rotary Actuators

Unlike manual rotary actuators, electric rotary actuators use distributed control systems. It drives using a worm-gear reducer. Lastly, electric rotary actuators use reversible motors to move the valves in an open and closed position.

  1. Hydraulic-Powered Rotary Actuators

It uses the application of fluid power or hydraulic oil to move rack-and-pinion assembly.

Also, it includes a cylinder and a set of helical gears to convert straight line input to a rotary output.

How to Select the Rotary Actuator

Before you start working with any rotary actuators, make sure to know where to use it. Here are some essential things to consider:

  1. Rotation: You need to know what angle of rotation you need to apply.
  2. Torque: The torque depends on the force being applied to an object. Make sure you know how much torque is required.
  3. Size:  You need to know the torque and the angle of rotation for you to decide what size of rotary actuators you will need.

Application of Rotary Actuators to Automation

Combining the rotary actuators in factory automation will increase in the line of production, powering method, and improves the mechanical characteristics of machines. Below are some of the significant applications of rotary actuators.

  1. Drag and Drop Application

You can apply the rotary actuators to pick-and-place clamps or handlers of the robot machines. You can apply using either electric or even hydraulic-powered actuators.

  1. Miniature Application

Miniature actuators are capable of moving in a small confined space. One best example of it is using a solenoid valve, which produces oscillating motion through the power of magnetic fields.

  1. Automobile Construction-Equipment Industry

One of the significant usages of rotary actuators, especially using hydraulic-powered robot equipment. Actuators are being used where the rotary motion is less, and a compact solution is required.

  1. Welding Robots Application

Welding robots provide a wide range of intelligent functions. It offers efficiency, load capacity, and speed for welding parts of all sizes and shapes. These welding robots primarily use a rotary actuator to perform its function effectively. Also, it allows the welding robots to extend its full range of motion.

  1. Assembly Robots

When it comes to assembling parts, we cannot deny the fact that robots can move faster than humans. Also, they have higher precision and can produce 100% efficiency of output in a short time. Like welding robots, this kind of automation also uses rotary actuators.


Rotary actuators can always combine with the application of robotics. It will generate high levels of power and torque, which is needed to produce top standard products. As a result, it enables manufacturing industries to run with a lesser workforce. Still, it yields a higher profit to the manufacturing industries.
