Discover the enhanced stability and non-rotating precision of our double rod cylinders. Designed for applications requiring balanced force output and resistance to side loads, these cylinders offer superior performance and reliability for your demanding automation tasks.
With piston rods extending from both ends, these cylinders provide equal force and speed in both directions of travel, ideal for push-pull applications.
The dual rod design inherently prevents piston rod rotation, ensuring accurate alignment and positioning for tasks requiring non-rotational movement.
Offers increased resistance to side loads and bending moments compared to single rod cylinders, leading to greater stability and longer service life.
Double rod cylinders feature a single piston with two piston rods extending in opposite directions from the cylinder body. This design provides inherent stability and allows for work to be performed at both ends simultaneously or alternately.
High-tensile strength piston rods with hard chrome plating for superior wear resistance and smooth operation.
Utilizing advanced sealing materials and design to minimize friction, prevent leakage, and ensure extended operational life.
Some series offer integrated guide bushings or options for external guides to further enhance stability against side loads and moments.
We offer customization for stroke length, mounting styles, and materials to meet specific application requirements.

Offering balanced clamping force from two sides, ideal for securing workpieces during machining or assembly.
Providing smooth and controlled motion for opening and closing automated doors, gates, or hatches.
Ensuring precise, non-rotating movement for applicator heads or print heads.
Where two points need to be actuated simultaneously with balanced force, e.g., lifting platforms.
Adhering to proper installation and maintenance practices will maximize the performance and lifespan of your double rod cylinders.
Choose a double rod cylinder when your application requires one or more of the following:
Not exactly. A double rod cylinder has a single piston. The force output is determined by the air pressure acting on the area of this piston.
Since both rods are typically the same diameter, the effective area for extension and retraction is very similar, leading to balanced forces. However, it doesn’t provide “twice the force” of a single rod cylinder of the same bore size. The primary benefit is not doubled force, but rather balanced force, non-rotation, and improved stability.
The stroke length for a double rod cylinder is defined as the total distance the piston travels from one extreme end position to the other. This means it’s the distance one rod end moves relative to the cylinder body when the piston moves fully from one end cap to the other.
It’s important to note that because there are rods extending from both ends, the overall length of the cylinder assembly (body + fully extended rods) will be greater than a single rod cylinder with the same stroke. However, the “working envelope” or the space required for the moving parts might be different depending on how the load is attached and where the cylinder body is fixed.
Controlling double rod cylinders is generally similar to controlling standard double-acting single rod cylinders. You would typically use a 5-port, 2-position (5/2) or 5-port, 3-position (5/3) directional control valve.
Key considerations include:
Standard double rod cylinders typically feature piston rods of the same diameter and equal extension from the center of the piston to achieve balanced performance. This is the most common configuration.
However, for specific applications, customized versions might be possible, though less common:
If you have such a unique requirement, it’s best to discuss it with our engineering team. We can explore the feasibility and potential design implications for a custom solution.
