About the Airtac SE80 Standard Cylinder SE80AX425S
The AirTAC SE80AX425S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics. It generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, utilizing an 80 mm bore and a 25 mm rod. The barrel is a square extruded aluminum profile without external tie rods, which keeps the body compact, corrosion-resistant, and easy to mount flush against machine frames.
This specific configuration includes a SUS420J2 stainless steel rod (code A) for superior resistance to corrosion and washdown environments. The built-in magnet (code S) enables seamless position sensing with AirTAC CMSE reed and DMSE electronic switches fitted into the sensor grooves on three sides of the body. The field-adjustable air cushioning at both ends allows you to tune end-of-stroke deceleration precisely, preventing hard impacts during high-speed 30-800 mm/s cycling.

Where the Airtac SE80 Standard Cylinder SE80AX425S Is Used
Palletizer Pusher
Uses the 2513 N push force at 0.5 MPa to index filled pallets onto a wrapping station, relying on the SUS420J2 rod to withstand occasional washdowns.
Injection Mold Ejection
Drives a mold ejection plate over the 425 mm stroke, utilizing the adjustable pneumatic cushions to soften the rapid retraction of heavy plastic parts.
Metal Press Leveling
Applies up to 513 kgf of clamping pressure to flatten stamped sheet metal components, with the built-in magnet triggering a DMSE sensor to confirm press closure.
Is the Airtac SE80 Standard Cylinder SE80AX425S the Right Cylinder?
If your application requires less force, stepping down to the 63 mm bore yields a 1559 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides a 3927 N push. At 425 mm of stroke, the unsupported rod length is significant; the 25 mm rod and M20x1.5 thread can carry substantial side loads, but you must use an external guide to prevent rod-bearing bending and premature seal failure. As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, allowing you to use standardized mounting accessories (like FA or TC hardware) for quick retrofits.
Remember that a standard SE cylinder does not hold its position or load if air pressure is lost or the valve is centered; the piston will drift. If your machine requires mechanical position holding without live pressure, consider the BSE rod-lock variant 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 SE80AX425S FAQ
The 80 mm bore generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa, the push force is 3518 N, with a maximum push of 513 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
Yes, the SE80AX425S is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards, meaning it shares the exact mounting footprint and PT3/8 port locations of other standard ISO 15552 profile cylinders for drop-in replacement.
