About the Airtac SE80 Standard Cylinder SE80X50SFB
The AirTAC SE80X50SFB is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It delivers a substantial 2513 N push force at 0.5 MPa, utilizing an 80 mm bore and a 50 mm stroke. This specific configuration includes a rear flange (FB) mount and a built-in magnet for position sensing.
Its extruded aluminum barrel omits external tie rods, creating a flush, corrosion-resistant profile that simplifies mounting and keeps the unit compact. The field-adjustable air cushioning at both ends allows you to tune end-of-stroke deceleration, softening hard impacts when moving heavy loads at speed. Because it includes the -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac SE80 Standard Cylinder SE80X50SFB Is Used
Press Die Ejection
Provides the 2513 N push force required to eject heavy stamped metal sheets from press dies, utilizing the FB rear flange to securely anchor the cylinder against high reverse shock loads.
Pallet Flap Folding
Drives the mechanical arms that fold large cardboard flaps on automated palletizing lines, where the 50 mm stroke delivers rapid, high-force actuation within a compact footprint.
Heavy Log Stops
Acts as a heavy-duty stopper block on timber processing conveyors, raising a 25 mm rod barrier instantly to halt advancing logs weighing several hundred kilograms.
Is the Airtac SE80 Standard Cylinder SE80X50SFB the Right Cylinder?
This 80 mm bore provides 2513 N of push at 0.5 MPa. If your application requires less force, the neighboring 63 mm bore offers 1559 N of push; if you need more power, stepping up to the 100 mm bore yields 3927 N. As a standard ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, making it a drop-in replacement for retrofits. It uses a PT3/8 port and an M20x1.5 rod thread. Note that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; if your workflow must hold a vertical load without live pressure, consider a BSE rod lock variant.
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.
