Select a cylinder, prolong its life by reducing wear, and trigger automated processes with sensors.
About Gas Springs
Gas springs are typically used to assist in opening lids, covers, windows, conveyors, and seats—similar to a hatchback opening on a car.

Impact-Resistant Round Body Air Cylinders
Built to withstand hard knocks, these cylinders have a thick barrel wall for more durability than standard air cylinders. They combine the form of a round body air cylinder with the rugged construction of a tie-rod body air cylinder. All are double acting; they use air to exert force in both directions.
Face/pivot-mount cylinders have mounting holes on both ends, so you can install in a fixed position or in a pivoting mount. Sensor-ready cylinders have a magnetic piston to activate relays and controllers. When the piston moves past the sensor (sold separately), the sensor activates. You can use multiple sensors. Attach one for each action you want to trigger.

Tie Rod Air Cylinders
Rods along the barrel of these cylinders secure the end caps and shield the barrel from impact.
Sensor-ready cylinders have a magnetic piston that can trigger one or more sensors (sold separately) to activate relays and controllers.
Cushioned cylinders have adjustable air cushions that absorb piston impact to minimize wear and noise. Turn the screws at each port to adjust the amount of cushion.

NFPA Tie Rod Air Cylinders

Made to fit the most common mounting footprint, these cylinders have an NFPA (National Fluid Power Association) industry-standard footprint, ensuring easy interchangeability. They have a magnetic piston, so you can use sensors (sold separately) to activate relays and controllers.
Cushioned cylinders have adjustable air cushions that absorb piston impact to minimize wear and noise. Turn the screws at each port to adjust the amount of cushion.

Connect these mounts to an air cylinder to create linear, pivot, or arc movements. These mounts are compatible with NFPA tie rod air cylinders.
Front or rear flanges are for straight, back-and-forth movements. These flanges mount to either end of your cylinder.
Pivot brackets and clevis brackets work together to allow the rear portion of cylinders to pivot back and forth. Use either with a clevis rod end to create arcing movements. Rod clevises allow the front portion of cylinders to pivot.

Connect these mounts to an air cylinder to create linear, pivot, or arc movements. These mounts are compatible with NFPA tie rod air cylinders.
Front or rear flanges are for straight, back-and-forth movements. These flanges mount to either end of your cylinder.
Pivot brackets and clevis brackets work together to allow the rear portion of cylinders to pivot back and forth. Use either with a clevis rod end to create arcing movements. Rod clevises allow the front portion of cylinders to pivot.

Washdown NFPA Tie Rod Air Cylinders
Made with an NFPA industry standard footprint and a stainless steel body, these cylinders are easily interchanged with the most common mounting footprint and withstand chemicals, corrosive solutions, and washdowns. They have a rod wiper that keeps contaminants out. These cylinders contain a magnetic piston that can activate relays and controllers when you attach one or multiple sensors (not included). Use one sensor for each action you want to trigger. When the piston moves past the sensor, the sensor activates. These cylinders have self-adjusting cushions that automatically compensate for changes in load and speed.

Rodless Air Slides
With no external moving parts, these air slides provide a long stroke, but have a static footprint—only the carriage on top moves. They have a magnetic piston so you can use them with sensors (not included) to activate relays and controllers.
Sensor-ready slides have adjustable air cushions that absorb piston impact to minimize wear and noise. Turn the screws to adjust the amount of cushion. Barrel, end caps, and slide are aluminum.
Sensor-ready low-profile slides have a shorter height than standard slides to fit in tight locations. Barrel is aluminum and end caps and carriage are plastic.

High-Load Rodless Air Slides
Move heavy loads back and forth—these air slides have over twice the capacity as standard rodless ones. They are often used for high-volume diverting and sorting. Only the carriage moves, so they provide a long stroke but have a static footprint.
The piston is magnetic, so you can use these slides 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.

Corrosion-Resistant Reducible-Force Gas Springs with Eyelet Fittings



Made from stainless steel for excellent corrosion resistance in damp environments. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements. They come charged to their maximum force. Use the included tool to open the valve and bleed off the gas—there's no disassembly required. Release gas in very small increments and then test your application. Once gas is released, the force is permanently reduced. Gas springs have an eyelet end fitting on each end; requires an eyelet mounting bracket (sold separately) for mounting.
Rod protectors (sold separately) prevent impact damage.
Regulator kits (sold separately) indicate how much gas you’re releasing. Kits contain fittings to connect to your gas spring, a pressure gauge, a manifold, and instructions.

Remote-Release Gas Springs
Pair one of these gas springs with a release control to stop and release the gas spring anywhere along the stroke with the push of a button or lever. A valve on the rod end controls extension and compression and is operated with a release control (sold separately). Gas springs have a ball socket end fitting and ball stud on one end for mounting. The ball socket end fitting rotates in any direction on the ball stud to compensate for misalignment.
Release controls (sold separately) thread onto the rod end of the gas spring. They have an integral eyelet fitting for mounting the gas spring. Push-button release control requires an eyelet mounting bracket (not included) to mount the gas spring. Lever release control requires a bolt or pin (not included) to mount the gas spring.
