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.

Nonrotating NFPA Tie Rod Air Cylinders
 |
Cylinders have two parallel piston rods that prevent twisting as they extend and retract. 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 them with sensors (sold separately) to activate relays and controllers.
