Select a cylinder, prolong its life by reducing wear, and trigger automated processes with sensors.
Tie Rod Air Cylinders
 |
Rods along the barrel of these cylinders secure the end caps and shield the barrel from impact.
Sensor Ready—Sensor-ready cylinders have a magnetic piston that can trigger one or more sensors (sold separately) to activate relays and controllers.
Adjustable Cushion—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.
