Select a cylinder, prolong its life by reducing wear, and trigger automated processes with sensors.
NFPA Tie Rod Air Cylinders

Made to fit the most common mounting footprint, these cylinders have an NFPA (National Fluid Power Association) industry-standard footprint, ensuring easy interchangeability. They have a magnetic piston, so you can use sensors (sold separately) to activate relays and controllers.

Connect these mounts to an air cylinder to create linear, pivot, or arc movements. These mounts are compatible with NFPA tie rod air cylinders.
Front or rear flanges are for straight, back-and-forth movements. These flanges mount to either end of your cylinder.
Pivot brackets and clevis brackets work together to allow the rear portion of cylinders to pivot back and forth. Use either with a clevis rod end to create arcing movements. Rod clevises allow the front portion of cylinders to pivot.

Tie Rod Air Cylinders
Rods along the barrel of these cylinders secure the end caps and shield the barrel from impact.
Sensor-ready cylinders have a magnetic piston that can trigger one or more sensors (sold separately) to activate relays and controllers.
Cushioned cylinders have adjustable air cushions that absorb piston impact to minimize wear and noise. Turn the screws at each port to adjust the amount of cushion.
