About Air Cylinders

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.

The magnetic piston inside these cylinders can activate relays and controllers when used with a sensor (not included). When the piston moves past the sensor, the sensor activates. You can use multiple sensors—attach one for each action to trigger.

Cylinders are universal mount, so they have threads on both ends to mount in a fixed position or you can use the hole on the back end to pivot mount.

Cushioned Round Body Air Cylinders

Designed to keep the piston from slamming against the cylinder body, these cylinders have adjustable air cushions at each end to minimize wear and noise. Turn the screws to adjust the amount of cushion.

Cylinders are universal mount, so they have threads on both ends to mount in a fixed position or you can use the hole on the back end to pivot mount.

Enclosed-Body Load Responsive Cushion Tie Rod Air Cylinders

Ensure the correct cushioning, even with changing loads. These cylinders have self-adjusting cushions that automatically compensate for changes in load and speed. They have an extruded-aluminum body so there's no open spaces for debris to collect. All have a magnetic piston so you can use them with sensors (sold separately) to activate relays and controllers.

Enclosed-Body NFPA Tie Rod Air Cylinders

Cylinder

An extruded-aluminum body means these cylinders have no open spaces for debris to collect. They have an NFPA (National Fluid Power Association) or ISO industry-standard footprint for easy interchangeability. They’re cushioned to absorb piston impact to minimize wear and noise—cylinders have a screw at each port so you can adjust the amount of cushion. All have a magnetic piston so you can use them with sensors (sold separately) to activate relays and controllers.

Load-Stopping Air Cylinders

When the rod extends, the load stops.

Control the movement of loads on your conveyor—the rod on these air cylinders extends to stop loads and retracts to let them pass. While standard air cylinders have a weaker rod that will bend with side impact, these air cylinders have a thick carbon steel rod that won’t bend. The rod is also chrome plated, so it won’t corrode in wet environments.

To activate relays and controllers using these air cylinders, add a sensor (sold separately).
