    industrial info icon

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

    NFPA Tie Rod Air Cylinders

    Image of Product. Front orientation. Contains Annotated. Air Cylinders. 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 mounts to an air cylinder to create linear, pivot, or arc movements. Mounts are compatible with NFPA tie rod air cylinders.

    Washdown NFPA Tie Rod Air Cylinders

    Image of Product. Front orientation. Contains Annotated. Air Cylinders. Washdown NFPA Tie Rod Air Cylinders.
    Made with an NFPA industry standard footprint and a stainless steel body, these cylinders are easily interchanged with the most common mounting footprint and withstand chemicals, corrosive solutions, and washdowns. They have a rod wiper that keeps contaminants out. These cylinders contain a magnetic piston that can activate relays and controllers when you attach one or multiple sensors (not included). Use one sensor for each action you want to trigger. When the piston moves past the sensor, the sensor activates. These cylinders have self-adjusting cushions that automatically compensate for changes in load and speed.

    Hold your piston's position during an emergency stop or power loss to keep your load safely in place. These rod locks also prevent your piston from drifting past its stopped position as it wears and loses precision. They fit an NFPA industry-standard footprint, so they’re easy to mount to a cylinder. You can unmount and reuse them as needed. With an anodized housing, they resist wear and corrosion.
