About the Airtac SE80 Standard Cylinder SE80BX125S
The AirTAC SE80BX125S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a robust 2513 N push force at 0.5 MPa (3518 N at 0.7 MPa) across a 125 mm stroke. Equipped with a SUS304 stainless steel rod (code B), it is purpose-built for corrosive environments and washdown duty where standard carbon steel rods would fail.
The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machinery. Integrated sensor grooves on three sides accept CMSE reed and DMSE electronic switches via the built-in -S magnet. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration, softening hard impacts during high-speed 30-800 mm/s cycles.

Where the Airtac SE80 Standard Cylinder SE80BX125S Is Used
Corrugated Box Flap Folding
Drives folding mechanisms on packaging lines, using the 2513 N push force to crease and close heavy corrugated flaps while the SUS304 rod resists humid washdown environments.
Bottling Line Diverter Gate
Actuates heavy lane dividers to sort glass or PET bottles, relying on the 125 mm stroke and adjustable end-cushions to soften stops at high 30-800 mm/s cycling speeds.
CNC Chip Blower Station
Pushes a rigid blast nozzle into the machining zone to clear metal chips, where the stainless steel rod prevents coolant corrosion and the square barrel mounts flush to the guard.
Is the Airtac SE80 Standard Cylinder SE80BX125S the Right Cylinder?
At 0.5 MPa, this 80 mm bore generates 2513 N of push force. If your application requires less force, the 63 mm bore offers 1559 N push; if you need more power, the 100 mm bore provides 3927 N push. Because this is a double-acting cylinder, it does not hold its position if air pressure is lost or the valve is centered—the piston will drift. For fail-safe load holding, consider the AirTAC BSE rod lock series or an external pilot-operated check valve. For dimensionally interchangeable ISO 15552 retrofits, match the 125 mm stroke, PT3/8 port, and your required mounting accessory.
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 SE80BX125S FAQ
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa, the push force is 3518 N. The maximum push force is 513 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes. The SE80BX125S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 80 mm bore, 125 mm stroke, PT3/8 port, and mounting hardware.
