Double-Acting Round Body Air Cylinders
Push and pull light duty loads. These air cylinders use compressed air to both extend and retract, so they operate at nearly full force in either direction. They have a round body—the most common style of air cylinder—making them more compact and better suited for tight spaces than cylinders with external tie rods.
Universal-mount cylinders have mounting threads on both ends. The back end has a pivot bushing, which allows for more mounting options than nose-mount cylinders. Nose-mount cylinders only have mounting threads on the front end, so they’re shorter than universal-mount cylinders.
Sensor-ready cylinders have a magnetic piston that can activate relays and controllers when used with a sensor (sold separately). When the piston moves past the sensor, the sensor activates. You can use multiple sensors—attach one for each action to trigger.

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.
Air-extend cylinders, also known as push style, use air to extend the rod. Air-retract cylinders, also known as pull style, use air to retract the rod.
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.
Nose-mount cylinders have threads on the front of the cylinder and install in a fixed position.

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. A common use for them is creating coordinated motion between two gates—opening one while the other closes. These cylinders are not repairable, so just swap in new ones when they wear out.
