Dust-Resistant Round Body Air Cylinders
Push and pull light duty loads in areas constantly exposed to dust and powders as fine as flour. With lubricant retainers around their piston to block particles, these cylinders last up to four times longer in dusty environments than standard air cylinders. They’re often used in ceramics and paper manufacturing facilities. 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. All are universal mount, so they have threads on both ends. The back end has a pivot bushing, which allows for more mounting options than nose-mount cylinders.
These air cylinders have a magnetic piston that can activate relays and controllers when used with a sensor (sold separately). When the piston moves past a sensor, the sensor activates. You can use multiple sensors—attach one for each action to trigger.

Rotary Clamping Air Cylinders


Clamp items in place to complete a step in your manufacturing process. These air cylinders rotate while actuating, so you can position, assemble, and inspect items. The body of these air cylinders has threaded through-holes on the face and sides, so you can mount them directly to equipment and thread accessories on. The rod is internally threaded, allowing you to attach an arm as needed for your application.
The piston is magnetic, so you can use these slides with sensors (not included) 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.

Locking Tie Rod Air Cylinders
Halt actuation at a moment’s notice—these air cylinders have an end lock that acts as an emergency stop. If there's a sudden loss of air pressure, the end lock engages to safely hold the load. You can also set them to stop anywhere along the stroke length as a simpler alternative to electric actuators. Rods along the barrel secure the end caps and shield the barrel from impact. These air cylinders are double acting, meaning they extend and retract with nearly equal force. All have adjustable air cushions that absorb piston impact to minimize wear and noise.
The magnetic piston inside these cylinders 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.

Load-Stopping Air Cylinders

Control the movement of loads on your conveyor—the rod on these air cylinders extends to stop loads and retracts to let them pass. While standard air cylinders have a weaker rod that will bend with side impact, these air cylinders have a thick carbon steel rod that won’t bend. The rod is also chrome plated, so it won’t corrode in wet environments.
To activate relays and controllers using these air cylinders, add a sensor (sold separately).




Heavy-Duty Load-Stopping Air Cylinders

Stop heavy material in its tracks. With the same footprint as regular load-stopping air cylinders, these air cylinders have a lever end that absorbs 30% more force. Plus, they’re tested to withstand twice as many cycles. Made of carbon steel, the rod extends to stop loads and retracts to let them pass. Even if material jams into the rod from an angle, it won’t bend or snap. Choose them for high-volume lines carrying heavy material, such as pallet conveyors.
To activate relays and controllers using these air cylinders, add a sensor (sold separately).
