About the Airtac SE80 Standard Cylinder SE80X50FTC
The AirTAC SE80X50FTC is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty positioning. It generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, utilizing an 80 mm bore and a 50 mm stroke. The extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant body that simplifies mounting and reduces debris accumulation in tight machine cells.
This specific SKU is configured with an FTC mounting accessory and a standard PT3/8 port. Because it lacks the -S magnet suffix, it is built without a built-in position sensor, relying on external limit switches or mechanical stops for end-position confirmation. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration, protecting the 25 mm hard-chrome rod from impact shock.

Where the Airtac SE80 Standard Cylinder SE80X50FTC Is Used
Press-Fit Pin Insertion
Drives dowel pins and alignment shafts into heavy steel fixtures, utilizing the 2513 N push force at 0.5 MPa to overcome insertion friction without stalling.
Corrugated Box Flap Folding
Actuates mechanical arms to fold heavy double-wall corrugated carton flaps, where the 80 mm bore provides the torque necessary to crease thick materials cleanly.
Injection Mold Platen Ejector
Pushes molded plastic parts off core pins during ejection cycles, relying on the adjustable air cushion to decelerate the 25 mm rod smoothly before the end cap.
Is the Airtac SE80 Standard Cylinder SE80X50FTC the Right Cylinder?
Selecting this 80 mm bore makes sense when your application requires substantial thrust, such as 2513 N push at 0.5 MPa, but you must verify if stepping down is viable. A 63 mm bore offers 1559 N of push at 0.5 MPa, which may suffice for lighter loads, whereas stepping up to a 100 mm bore yields 3927 N of push at 0.5 MPa for heavier tooling. This model uses an FTC mount and PT3/8 ports, ensuring it is dimensionally interchangeable with other ISO 15552 cylinders for seamless retrofits.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. If your fixture requires fail-safe load holding, you must integrate an external pilot-operated check valve or transition to a BSE rod-lock variant. At a 50 mm stroke, side-loading on the rod bearing is minimal, so an external guide is typically unnecessary.
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 SE80X50FTC FAQ
This 80 mm bore cylinder features a PT3/8 port and a 25 mm rod. At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N. The maximum push force is 513 kgf at 1.0 MPa.
Yes, the SE80X50FTC is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing FTC mounting footprints and use standard hardware. Note that because this specific SKU lacks the -S magnet, it will not trigger AirTAC CMSE or DMSE electronic position sensors without modifying the piston.
