About Air Cylinders

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

Round Body Air Cylinders

Double-Acting Round Body Air Cylinders

Push and pull light duty loads. These air cylinders use compressed air to both extend and retract, so they operate at nearly full force in either direction.

Single-Acting Round Body Air Cylinders

More basic and cost effective than double-acting cylinders, these single-acting cylinders exert force in one direction and have a spring to return the rod to its original position.

Mounts for Round Body Air Cylinders

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

Round Body Air Cylinders for Narrow Spaces

Also known as pancake cylinders, these deliver as much force as other cylinders, but with a shorter stroke to function in small spaces.

Miniature Threaded-Body Air Cylinders

These cylinders thread directly into your equipment, taking minimal space.

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.

Subminiature Round Body Air Cylinders

At less than two inches in length, these cylinders actuate small devices in spots where other cylinders don’t fit.

Double-Ended Round Body Air Cylinders

Unlike other air cylinders that push and pull one object, these double-ended cylinders push one object while pulling another.

Short-Stroke Clamping Air Cylinders

Also known as air clamps, these cylinders are used to apply force in holding applications.

Washdown Round Body Air Cylinders

Able to resist corrosive solutions and chemical environments, these cylinders withstand washdown conditions.

Nonrotating Round Body Air Cylinders

Keep tools from twisting while moving them back and forth.

Rotary Clamping Air Cylinders

Clamp items in place to complete a step in your manufacturing process.

Multiple-Stroke Round Body Air Cylinders

Move loads between three positions instead of two.

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.

Through-Hole Double-Ended
Round Body Air Cylinders

Simplify your setup by running fluid or air through the hollow piston in these air cylinders. The rod extends from both ends, so they can push an object and pull another at the same time, unlike standard air cylinders.

Dust-Resistant Round Body Air Cylinders

Push and pull light duty loads in areas constantly exposed to dust and powders as fine as flour.

Tie Rod Air Cylinders

Rods along the barrel of these cylinders secure the end caps and shield the barrel from impact.

Compact Tie Rod Air Cylinders

Get the power and stroke of other tie rod cylinders in less than half the space.

Impact-Resistant Compact Tie Rod Air Cylinders

Nonrotating Compact Tie Rod Air Cylinders

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.

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.

Mounts for NFPA Tie Rod Air Cylinders

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

Enclosed-Body Load Responsive
Cushion Air Cylinders

These cylinders have self-adjusting cushions that automatically compensate for changes in load and speed.

Nonrotating NFPA Tie Rod Air Cylinders

Cylinders have two parallel piston rods that prevent twisting as they extend and retract.

Enclosed-Body NFPA Air Cylinders

An extruded-aluminum body means these cylinders have no open spaces for debris to collect.

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.

Mounts for ISO Tie Rod Air Cylinders

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

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.

Locking Tie Rod Air Cylinders

Halt actuation at a moment’s notice—these air cylinders have an end lock that acts as an emergency stop. If there's a sudden loss of air pressure, the end lock engages to safely hold the load.

Rod Locks for NFPA Tie Rod Air Cylinders

Hold your piston's position during an emergency stop or power loss to keep your load safely in place. These rod locks also prevent your piston from drifting past its stopped position as it wears and loses precision.

Flexible-Mount Air Cylinders

Threaded through-holes in each corner allow you to mount these cylinders directly to equipment or mount with attachments.

Thin-Profile Flexible-Mount Nonrotating Air Cylinders

Clean Room Flexible-Mount Air Cylinders

Mount these cylinders directly to equipment in environments where contamination is a concern, such as electronics manufacturing.

Flexible-Mount ISO Air Cylinders

For multiple mounting options, these air cylinders match an industry standard ISO footprint and have threaded holes on the face and sides.

Vacuum Lifting Air Cylinders

Combine the lifting power of a vacuum with the actuation of an air cylinder to automate processes such as pick and place. With a hollow rod that’s threaded to connect to a vacuum pad, these cylinders let you move items with suction.

Easy-Install Flexible-Mount Air Cylinders

With an integrated valve and multiple mounting options, these air cylinders install quickly, right where you need them, to push and pull light loads.

Load-Stopping Air Cylinders

Control the movement of loads on your conveyor—the rod on these air cylinders extends to stop loads and retracts to let them pass.

Parts Metering Air Cylinders

Space out parts on your conveyor line or vibratory feeder. Also known as escapements, these air cylinders have at least one finger that extends to hold parts and then retracts to release them.

Heavy-Duty Load-Stopping Air Cylinders

Stop heavy material in its tracks. With the same footprint as regular load-stopping air cylinders, these air cylinders have a lever end that absorbs 30% more force.
