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

Instead of attaching your round body air cylinder directly to equipment, add a mount to best suit your application.
Foot brackets prevent cylinders from moving back and forth.
Pivot brackets for universal-mount air cylinders allow the rear portion of cylinders to pivot back and forth.
Rod clevises thread to cylinder shafts to allow swiveling.
Rod ends are internally threaded. They have an eyelet and ball that swivel to support angular misalignment and allow for pivoting.
Rod end nuts are internally threaded. They have an eyelet to make pivoting and hinge movements.
Stainless steel mounts are more corrosion resistant than steel and aluminum for use in wet or damp environments.
