Simplify your setup by running fluid or air through the hollow piston in these air cylinders. Use them to move loads while also lubricating equipment or blowing debris off parts with compressed air. The rod extends from both ends, so they can push an object and pull another at the same time, unlike standard air cylinders. For example, they can coordinate motion between two gates by opening one while closing the other. They’re double acting, so they use air to exert force when they both extend and retract.

These cylinders have a round body without external tie rods, so they fit in tight spaces. To mount them, use the threads on the ends of the cylinder.

The piston is magnetic, so you can use these cylinders with sensors (sold separately) to activate relays and controllers. When the piston moves past a sensor, the sensor activates. You can use multiple sensors—one for each action you want to trigger.
