Select a cylinder, prolong its life by reducing wear, and trigger automated processes with sensors.
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. They have holes for mounting.

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.
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.

Impact-Resistant Compact Tie Rod Air Cylinders
Small and durable, these cylinders have a high-strength plastic composite barrel that doesn’t dent. Cylinders have holes for mounting; the back end must be mounted against a solid surface.
