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.
Compact Tie Rod Air Cylinders
Get the power and stroke of other tie rod cylinders in less than half the space. Cylinders have holes for mounting; one end must be mounted against a solid surface.
Sensor-ready cylinders have a magnetic piston that can trigger one or more sensors (sold separately) to activate relays and controllers.

Nonrotating Compact Tie Rod Air Cylinders

These cylinders have two parallel piston rods that prevent the head from twisting as they extend and retract. They pack force into a smaller footprint than our other tie rod cylinders. Cylinders have holes for mounting; the back end must be mounted against a solid surface.
Sensor-ready cylinders have a magnetic piston that can activate relays and controllers when used with one or more sensors (sold separately).

Dust-Resistant Air Slides
Move grippers, printing heads, and other devices in areas constantly exposed to dust and powders as fine as flour. These slides last up to six times longer than standard air slides in extremely dirty, dusty environments, such as ceramics and paper manufacturing facilities. They have scrapers that wipe the rods clean and lubricant retainers that block particles. The air slide guide rods keep the head from twisting as it extends and retracts for steadier motion than air cylinders. They also have a larger mounting area, which makes it easier to mount devices you want to actuate to the end of the slide.
The piston is magnetic, so you can use these slides with sensors (sold separately) to activate relays and controllers. When the piston moves past a sensor, the sensor activates. You can use multiple sensors—one for each action you want to trigger.
