About the Airtac SE80 Standard Cylinder SE80AX125S
The AirTAC SE80AX125S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics. It delivers a robust 2513 N push force at 0.5 MPa (3518 N at 0.7 MPa) across a 125 mm stroke. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against frames while resisting mechanical snagging.
This specific configuration features a SUS420J2 stainless steel rod (code A) for superior resistance to washdowns and corrosive environments. The built-in magnet (code S) directly supports AirTAC CMSE reed and DMSE electronic position sensing. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to dial in end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s operations.

Where the Airtac SE80 Standard Cylinder SE80AX125S Is Used
Corrugated Box Folding
Drives heavy folding mechanisms on corrugated packaging lines, utilizing the 2513 N push force and SUS420J2 stainless rod to withstand abrasive paper dust and frequent washdowns.
Bottling Line Diverter
Actuates heavy lane diverter gates on high-speed bottling conveyors, relying on the 125 mm stroke and DMSE electronic sensors for rapid, precise routing of glass containers.
Injection Mold Ejection
Provides secondary ejection force for injection molding machines, where the 3518 N thrust at 0.7 MPa safely separates dense plastic parts from stubborn mold cavities.
Is the Airtac SE80 Standard Cylinder SE80AX125S the Right Cylinder?
If 2513 N push at 0.5 MPa is excessive for your load, step down to the 63 mm bore, which yields 1559 N. If you need more thrust, the 100 mm bore provides 3927 N. 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 center trunnions.
The 125 mm stroke is well within standard limits, but note that the plain SE cylinder cannot hold a load or maintain its position if air pressure drops or the valve centers—the piston will drift. For critical load-holding safety, consider the BSE rod-lock variant. The adjustable air cushion only decelerates the piston near stroke end; it does not act as a brake.
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 SE80AX125S FAQ
