Hollow rod cylinders are engineered with a central bore running through the length of the piston rod, allowing them to exert force in two different directions via a single cylinder. This design facilitates pulling applications by passing a tensioning rod through the center, enabling the cylinder to pull a load rather than just pushing it.

They are available in both single-acting (spring return) and double-acting configurations, with the double-acting option providing more controlled retraction.

The cylinders are constructed from durable materials like high-alloy steel or lightweight aluminum, often finished with corrosion-resistant coatings to ensure longevity in harsh environments.

To further enhance their versatility and ease of use, many models feature collar threads for simple fixturing and base mounting holes for secure installation.

Dual wiper seals help protect the internal mechanisms from contaminants and debris, ensuring reliable operation and extending the cylinder’s service life.
