Double-acting actuators with single-sided piston rod – the key to efficiency in modern pneumatic technology

Pneumatic actuators, the heart of modern manufacturing automation, play a key role in many industries. But have you ever wondered what the differences are between different types of actuators and how they affect production efficiency? [Find out more]

Variety of pneumatic actuators

Not all actuators are the same. Among them, we distinguish actuators that perform rectilinear motion:

  • single-acting (pushing, pulling),
  • double-acting;

and actuators performing rotary motion:

  • swinging SWH series,
  • rotary ADA and ASR series.

Construction and operation of pneumatic actuators

A pneumatic actuator consists of a piston and a piston rod that move in a closed cylinder. It is the piston that performs the desired movement, driven by compressed air. In single-acting actuators we are dealing with a single connection through which air is introduced, the return of the piston is carried out by a spring. On the other hand, in the case of double-acting actuators, we have two connections – one for extending and the other for retracting the piston. Important components of any actuator are seals, which are responsible for proper operation (tightness and resistance to movement). [Read more about actuator maintenance]

Advantages of double-acting actuators

Double-acting actuators with a single-sided piston rod feature greater control over movement. With two ports through which air flows, faster and more precise operation is possible. They are also more efficient and consume less energy. This makes them applicable to more complex systems where greater precision and speed are required.

Application of double-acting actuators

These actuators are widely used in many industries (chemical, mining, wood, plastics, food, rail), robotics, medicine or even space programs. They are used to open and close doors, lift and move goods from conveyor belts or in earth-moving machinery.

Further consideration of pneumatic actuators

Pneumatic actuators, especially those double-acting with a single-sided piston rod, are the result of years of research and development in pneumatic technology. Their advanced design and functionality make them indispensable in many industrial applications.

History of pneumatic actuators

The history of pneumatic actuators goes back centuries. The first prototypes were simple and mainly used for basic applications. However, over time, due to technological advances, actuators became more advanced and began to be used in more complex systems. [History]

The technology behind the actuators

The advanced technology behind double-acting actuators with single-sided piston rods allows for precise motion control. As a result, they are able to operate under extreme conditions, such as high temperatures or pressures.

Future applications

The application possibilities for pneumatic actuators are almost limitless. In the future, we can expect them to be used in even more advanced systems, such as autonomous vehicles and industrial robots.

Summary

Choosing the right actuator depends on a number of factors, such as the type of task, operating environment and temperature, budget or precision required. Double-acting actuators with a single-sided piston rod offer a number of advantages that make them a popular choice for professionals in various industries. If you are considering choosing the right actuator for your project, this type of device is worth considering. Contact us at CPP “PREMA” S.A. to learn more.
