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

Miniature Threaded-Body Air Cylinders
These cylinders thread directly into your equipment, taking minimal space.
Single-acting cylinders are push style—air extends the rod and cylinders have a spring that returns the rod to its original position.
Double-acting cylinders exert force in both directions.

Hydraulic Cylinders
For easy interchangeability, the mounting footprint of these cylinders meets NFPA and JIC (Joint Industrial Congress) industry standards. All have two hydraulic ports: one to extend the piston rod and another to retract it. Cylinders with no cushion have a compact size.

Weather-Resistant Replaceable-Cylinder Padlocks


Simplify keying and rekeying around your facility, both indoors 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).
Padlocks with a dual-locking shackle prevent attempts to break them open from prying, shimming, or tapping because both ends of the shackle lock inside the padlock body.
Brass-body locks resist corrosion better than hardened-steel body locks. Those that are chrome plated have an added layer of corrosion protection and strength.
Brass shackles are more corrosion resistant than hardened-steel shackles, but they’re not as strong. Hardened-steel shackles are plated with a combination of copper, nickel, and chrome for corrosion resistance and strength. Stainless steel shackles resist corrosion better than both hardened steel and brass shackles.
