Airtac SE80 Standard Cylinder SE80AX350S
The AirTAC Airtac SE80 Standard Cylinder SE80AX350S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø80mm bore and 350mm stroke, PT3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE80 Standard Cylinder SE80AX350S
The AirTAC SE80AX350S is a double-acting single-rod ISO 15552 profile cylinder delivering a robust 2513 N push force at 0.5 MPa. It features a square extruded aluminum barrel without external tie rods, creating a compact, corrosion-resistant body that mounts flush against machine frames. The SUS420J2 stainless steel rod equips this unit for corrosive or washdown environments where standard carbon steel would fail prematurely.
This model includes a built-in magnet (-S) designed to interface directly with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. Field-adjustable air cushions at both ends allow you to tune the end-of-stroke deceleration via a set screw, softening hard impacts when moving heavy loads at speed. Note that this cushion acts only to slow the piston near the end caps; it is not a locking mechanism.

Where the Airtac SE80 Standard Cylinder SE80AX350S Is Used
Bottling Line Diverters
Leverages the 2513 N push force and SUS420J2 stainless rod to reliably divert heavy crate traffic on washdown bottling conveyors without corroding.
Corrugated Box Flap Folding
Uses the 350 mm stroke to reach across wide packaging stations, folding heavy corrugated flaps with precise CMSE sensor feedback for timing.
CNC Lathe Bar Feeder Pusher
Applies the adjustable air cushion to gently decelerate the 3518 N push force at 0.7 MPa when feeding bar stock into CNC lathes, preventing spindle damage.
Is the Airtac SE80 Standard Cylinder SE80AX350S the Right Cylinder?
If 2513 N of push force is more than your application requires, stepping down to a 63mm bore cylinder yields 1559 N at 0.5 MPa, saving valuable space and air consumption. Conversely, if you need to move heavier payloads, the 100mm bore provides 3927 N at 0.5 MPa. Because this is a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standardized mounting hardware like FA front flanges or TC trunnions.
At a 350 mm stroke, the 25 mm rod and M20x1.5 thread carry substantial side-load capacity, but long unsupported strokes inherently induce rod-bearing bending. For heavy off-center loads, you must use an external guide to prevent premature seal wear. Remember that a plain SE cylinder will drift if air pressure is lost or the valve is centered; if your application must hold a vertical load without live pressure, pair it with a BSE rod lock or an external pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE80 Standard Cylinder SE80AX350S FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At 0.7 MPa, the push force is 3518 N. The maximum push force is 513 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
Yes, the SE80AX350S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact same mounting footprint and port dimensions (PT3/8) as other standard profile cylinders, allowing for seamless retrofits without modifying the machine frame.
