About Air Cylinders

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

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. 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.

Universal Mount

Universal-mount cylinders have threads on both ends to mount in a fixed position, or you can use the hole on the back end to pivot mount. They come with two nuts and a pivot pin with retaining rings.

Sensor-Ready Nose Mount

Image of Product. Front orientation. Contains Annotated. Air Cylinders. Impact-Resistant Round Body Air Cylinders, Nose 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.

Nose-mount cylinders have threads and a nut on the front of the cylinder and install in a fixed position horizontally or vertically.

Weather-Resistant Replaceable-Cylinder Padlocks


Style A

Simplify keying and rekeying around your facility, both indoor and out. Instead of replacing the entire lock, just slot your own cylinder into these padlocks. Use them to match existing keying when expanding your facility, even if the key number isn’t common. Made from materials that resist corrosion from rain and snow, use them to secure outdoor equipment and gates. They accept easy-change lock cylinders, which are also called small format interchangeable core (SFIC) cylinders. To install and remove a cylinder, you'll need a control key that matches the cylinder (not included).

Brass Body with Brass Shackle—Both the body and shackle are brass, so these locks withstand corrosion better than locks with a steel body or shackle. However, they're not as strong.

Brass Body with Hardened Steel Shackle—With a brass body, these locks resist corrosion better than steel and zinc locks. Their shackle is hardened steel to withstand cutting and prying.

Brass Body with Stainless Steel Shackle—Made of brass, these locks withstand corrosion better than steel locks. Their shackle is stainless steel, the most corrosion-resistant shackle material we offer.

Chrome-Plated Brass Body with Hardened Steel Shackle—The shackle is hardened steel to withstand cutting and prying. With a brass body, these locks resist corrosion better than steel locks. A chrome plating adds an extra layer of protection against rain and snow.
