About the Airtac SE80 Standard Cylinder SE80X250S
The AirTAC SE80X250S is a double-acting single-rod profile cylinder built to the ISO 15552 dimensional standard. It delivers a substantial 2513 N push force at 0.5 MPa and features a 250 mm stroke, making it well suited for heavy-duty positioning tasks. The extruded aluminum barrel lacks external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific unit includes a built-in magnet (-S) for non-contact position sensing with AirTAC CMSE reed or DMSE electronic switches. To protect payloads at high cycling speeds, field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw rather than relying on a fixed rubber bumper.

Where the Airtac SE80 Standard Cylinder SE80X250S Is Used
CNC Lathe Chucking
Actuates heavy tailstock or pneumatic chuck clamping mechanisms, utilizing the 2513 N push force to secure large steel billets during high-torque turning operations.
Pallet Diverter Gate
Drives a robust routing arm on a 250 mm stroke to redirect heavy-duty pallets between adjacent roller conveyor lines without stalling under high friction loads.
Corrugated Box Flap Folder
Executes rapid folding motions on large format corrugated carton flaps, where the adjustable end cushions absorb kinetic energy to prevent tearing the board at high speeds.
Is the Airtac SE80 Standard Cylinder SE80X250S 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 moving up to the 100 mm bore provides 3927 N of thrust. Keep in mind that a standard SE cylinder relies on continuous air pressure to hold its position; if air is lost or the valve centers, the piston will drift. For critical load-holding without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve. Additionally, with a 250 mm stroke and a 25 mm rod, the bending moment on the rod bearing increases under heavy side loads, so utilizing an external guide rail is recommended to prevent premature wear.
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 SE80X250S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force is 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
Yes. The SE80X250S is manufactured to the ISO 15552 profile standard, meaning its mounting interface and physical dimensions are fully interchangeable with other ISO 15552 cylinders. It uses a PT3/8 port and an M20x1.5 rod thread, and the built-in magnet supports AirTAC CMSE and DMSE sensors.
