A single-acting cylinder with spring return is a common component in vehicle technology and many other fields. But what exactly is behind this term? In this article, we will explain everything you need to know about single-acting cylinders with spring return – from their function and application examples to important tips for their use.
What is a Single-Acting Cylinder with Spring Return?
A single-acting cylinder with spring return is a type of hydraulic or pneumatic linear actuator that converts force into linear motion. Unlike a double-acting cylinder, it has only one port for the pressure medium (e.g., hydraulic oil or compressed air).

The movement of the cylinder takes place in two steps:
- Extension: The pressure medium flows through the port into the cylinder and pushes the piston out. The resulting force depends on the pressure of the medium and the piston area.
- Retraction: When the pressure is released, an integrated spring ensures that the piston is pushed back into its starting position.
Where are Single-Acting Cylinders with Spring Return Used?
Thanks to their simple design and functionality, single-acting cylinders with spring return are found in a variety of applications, including:
- Vehicle technology: In brakes, clutches, and other vehicle components where a defined return force is required.
- Mechanical engineering: In presses, lifting devices, and clamping tools where simple and reliable motion control is needed.
- Automation technology: In sorting systems, robotic arms, and other automated processes where fast and precise movement is required.
Advantages of Single-Acting Cylinders with Spring Return
The use of single-acting cylinders with spring return offers several advantages:
- Simple construction: Fewer components compared to double-acting cylinders, resulting in lower costs and reduced maintenance.
- Reliable return: The integrated spring ensures reliable retraction of the piston, even in the event of pressure drop.
- Compact design: Allows for use in confined spaces.
What to Consider When Choosing?
When selecting a single-acting cylinder with spring return, the following points should be considered:
- Stroke: The maximum distance the piston can travel.
- Force: The force that the cylinder can generate.
- Pressure range: The permissible operating pressure of the medium.
- Port size: The diameter of the port for the pressure medium.
Tips for Use
- Ensure the correct spring stiffness is selected to guarantee the desired return force.
- Provide regular maintenance and lubrication of the cylinder to extend its service life.
- Avoid overloading and impacts to prevent damage.
