    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.

    Thin-Profile Flexible-Mount Nonrotating Air Cylinders

    Image of Product. Front orientation. Air Cylinders. Thin-Profile Flexible-Mount Nonrotating Air Cylinders.
    Mount these cylinders wherever you need them—cylinders have holes on each side and the front, add attachments (not included) to provide many mounting options. These cylinders also have a non-rotating oval piston that prevents twisting as the piston rod extends and retracts. Piston is magnetic, so you can use these cylinders with sensors (not included) to activate relays and controllers.

    Washdown Round Body Air Cylinders

    Image of Product. Front orientation. Contains Annotated. Air Cylinders. Washdown Round Body Air Cylinders.
    Able to resist corrosive solutions and chemical environments, these cylinders withstand washdown conditions. 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. Since they’re double-acting, they use air to both extend and retract light duty loads at nearly full force in either direction. 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.
    Instead of attaching your round body air cylinder directly to equipment, add a mount to best suit your application.
    Universal Mount
    Universal-mount cylinders have a rod wiper to keep contaminants out.

    Impact-Resistant Round Body Air Cylinders

    Built to withstand hard knocks, these cylinders have a thick barrel wall for more durability than standard air cylinders. They combine the form of a round body air cylinder with the rugged construction of a tie-rod body air cylinder. All are double acting; they use air to exert force in both directions.
    Sensor-Ready Face/Pivot Mount
    Image of Product. Front orientation. Contains Annotated. Air Cylinders. Impact-Resistant Round Body Air Cylinders, Pivot Mount.
    Sensor-ready cylinders have a magnetic piston to activate relays and controllers. When the piston moves past the sensor (sold separately), the sensor activates. You can use multiple sensors. Attach one for each action you want to trigger.
    Face/pivot-mount cylinders have mounting holes on both ends, so you can install in a fixed position or in a pivoting mount.
