About the Airtac SAU Standard Air Cylinder SAU80X25
The AirTAC SAU80X25 is a double-acting profile-type cylinder engineered for high force in tight machinery envelopes. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, while sharing AirTAC SC-series mounting accessories. It delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, utilizing a 3/8" port and an M20x1.5 rod thread.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches. The standard TPU seals support temperatures from -20 to +70 C, though a Viton H option extends this to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X25 Is Used
Injection Mold Clamping
Provides high 2513 N clamping force to secure injection mold halves within a compact machinery frame.
Heavy Press Ejection
Ejects dense metal stampings from a press bed, using the short 25 mm stroke for rapid, heavy-duty ejection cycles.
Pallet Stopper Gate
Acts as a robust pneumatic stopper block on heavy-duty conveyor lines to halt loaded pallets securely.
Is the Airtac SAU Standard Air Cylinder SAU80X25 the Right Cylinder?
When sizing this 80 mm bore, compare it to its neighbors: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. Choose the SAU80X25 when you need substantial thrust in a compact footprint. For mounting, use SC-series LB foot brackets, FA/FB flanges, CA/CB clevises, or I/Y/F/U knuckles. Since this specific unit has no -S magnet, position sensing is not possible without modifying the assembly. If your application requires the load to stay put when air is removed, note that the adjustable air cushion only decelerates the piston near stroke end and acts purely as a shock absorber, never a lock. You must add an external rod lock or a pilot-operated check valve to prevent drifting.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAU Standard Air Cylinder SAU80X25 FAQ
The SAU80X25 features a 3/8" port and generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa the push force is 3518 N, and the theoretical maximum force is 513 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder. It is a compact profile cylinder that is shorter than ISO standards. Mounting compatibility is strictly with the AirTAC SC series, using LB, FA, FB, CA, or CB brackets.
