    About Air Cylinders
    industrial info icon

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

    Double-Acting Round Body Air Cylinders

    Push and pull light duty loads. These air cylinders use compressed air to both extend and retract, so they operate at nearly full force in either direction. 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.
    Instead of attaching your round body air cylinder directly to equipment, add a mount to best suit your application.
    Universal Mount
    Image of Product. Front orientation. Contains Annotated. Air Cylinders. Double-Acting Round Body Air Cylinders, Universal Mount.
    Universal-mount cylinders have mounting threads on both ends. The back end has a pivot bushing, which allows for more mounting options than nose-mount cylinders.
    Sensor Ready—Sensor-ready cylinders have a magnetic piston that can activate relays and controllers when used with a sensor (sold separately). When the piston moves past the sensor, the sensor activates. You can use multiple sensors—attach one for each action to trigger.
    Adjustable Cushion—Cylinders with an adjustable cushion absorb piston impact to minimize wear and noise. Turn the screws to adjust the level of cushioning.

    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.
