About the Airtac SE80 Standard Cylinder SE80AX120S
The AirTAC SE80AX120S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a robust 2513 N push force at 0.5 MPa. It features a 120 mm stroke and uses a 25 mm SUS420J2 stainless steel rod, making it highly suitable for corrosive or washdown environments where a standard carbon steel rod would fail. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames.
This model includes a built-in magnet (S code) for position sensing alongside field-adjustable air cushioning at both ends. The cushion screws allow you to tune end-of-stroke deceleration precisely, softening hard impacts when cycling at speeds up to 30-800 mm/s. It operates reliably between 0.15-1.0 MPa, integrating seamlessly into existing pneumatic setups via its PT3/8 ports.

Where the Airtac SE80 Standard Cylinder SE80AX120S Is Used
Corrugated Box Flap Folding
Provides the 2513 N push at 0.5 MPa required to cleanly fold heavy double-wall corrugated carton flaps during high-speed case sealing, utilizing the SUS420J2 rod to withstand occasional washdowns.
CNC Fixture Clamping
Secures heavy cast iron engine blocks on a machining center, using the 120 mm stroke to clear the workpiece during loading while the adjustable cushion softens the clamp impact to protect part integrity.
Pallet Diverting Gate
Actuates a heavy diverter arm on a packaging line, where the 3518 N push at 0.7 MPa easily redirects loaded wooden pallets and the no-tie-rod profile prevents debris accumulation.
Is the Airtac SE80 Standard Cylinder SE80AX120S the Right Cylinder?
Choosing this 80 mm bore makes sense when you need substantial thrust without stepping up to a larger footprint. If 2513 N push at 0.5 MPa is excessive, stepping down to the 63 mm bore yields 1559 N; conversely, scaling up to the 100 mm bore provides 3927 N. Because this is a double-acting cylinder, it will drift if air pressure is lost or the valve is centered, so a BSE rod lock variant is required if the application demands fail-safe load holding.
For ISO 15552 dimensional interchangeability, you can specify this exact 80 mm bore, 120 mm stroke, PT3/8 porting, and your desired mounting accessory to guarantee a drop-in replacement for other ISO 15552 cylinders. The integrated -S magnet enables direct mounting of CMSE reed or DMSE electronic sensors along the body's multiple sensor grooves without requiring additional brackets.
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 SE80AX120S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force due to the single-rod design. At 0.7 MPa, the push force increases to 3518 N. The absolute maximum push capacity is 513 kgf when operated at the maximum rated pressure of 1.0 MPa.
Yes, the SE80AX120S is dimensionally interchangeable per ISO 15552, meaning it serves as a drop-in replacement for other standard ISO 15552 profile cylinders using the same mounting footprint. Additionally, the built-in magnet is specifically designed to work with AirTAC CMSE reed switches and DMSE electronic sensors.
