About Air Cylinders

Select a cylinder, prolong its life by reducing wear, and trigger automated processes with sensors.

Enclosed-Body ISO Air Cylinders

An extruded-aluminum body means these cylinders have no open spaces for debris to collect. They have an ISO industry-standard footprint to match common mounting patterns for easy interchangeability. These cylinders are double-acting, so they exert force in both directions. To minimize wear and reduce noise, they cushion the impact of the piston with air. Adjust the amount of cushion with a screw at each port. All have a magnetic piston so, you can use them with sensors (sold separately) to activate relays and controllers. You can use multiple sensors—attach one for each action you want to trigger.

Connect mounts to an air cylinder to create linear, pivot, or arc movements. Mounts are compatible with ISO tie rod air cylinders.

Enclosed-Body Load Responsive Cushion 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.

Clean Room Round Body Air Cylinders

Minimize the release of particles that can damage electronics or contaminate batches as you push and pull light loads. These air cylinders are designed with seals and caps that prevent particles from escaping. A rod seal wipes grease particles off the rod as it moves back and forth. The seal is polyurethane, which is slippery, so it wears more slowly than standard seals, releasing fewer particles. These cylinders also have tightly crimped end caps to stop air from leaking.

With no tie rods on the outside, these round-body cylinders fit in tight spaces. They have an ISO industry-standard footprint that fits common mounting patterns for easy interchangeability. As universal-mount cylinders, they have mounting threads on both ends, giving you more mounting options than nose-mount cylinders. You can also pivot mount them with the through-hole on the back. They’re double acting, meaning they push and pull loads with equal force.

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.

Instead of attaching your round body air cylinder directly to equipment, add a mount to best suit your application.

Corrosion-Resistant ISO Tie Rod Air Cylinders

Our most corrosion-resistant air cylinders, these cylinders are made of stainless steel for use in wet environments. Rods secure the end caps and shield the barrel from impact. These air cylinders are double acting, meaning they push and pull loads with nearly equal force. They have an ISO industry-standard footprint to match common mounting patterns, so they’re easy to switch in and out across equipment.

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