What is a double-acting cylinder?

A double-acting cylinder is designed to utilize hydraulic or pneumatic pressure to create force in both extending and retracting motions. This means that it has two ports for fluid entry and exit, allowing for controlled movement in both directions. When fluid is directed into one side of the cylinder, it forces the piston to extend, and when the fluid is redirected, it allows the piston to retract.

This feature is critical for applications requiring precise control over the movements of machinery, as it enables tasks like lifting, pushing, and pulling to be performed efficiently. The ability to exert force in both directions enhances the versatility and effectiveness of the cylinder in various fluid power systems, making it a vital component in fields such as manufacturing and robotics.
