About Air Cylinders

Double-Acting Round Body Air Cylinders

Create linear motion with the most popular of our air cylinders.

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.

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.

Miniature Threaded-Body Air Cylinders

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

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.

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.

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.

Nonrotating Compact Tie Rod Air Cylinders

Impact-Resistant 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.

Enclosed-Body Load Responsive
Cushion Air Cylinders

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

Enclosed-Body NFPA Air Cylinders

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

Nonrotating NFPA Tie Rod Air Cylinders

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

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

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.
