Airtac SAU Standard Air Cylinder SAU80X15S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X15S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 15mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAU Standard Air Cylinder SAU80X15S
The AirTAC SAU80X15S is a double-acting profile-type cylinder engineered for high force in confined spaces. Its extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore, while delivering a push force of 2513 N at 0.5 MPa. It features a 3/8" port, an M20x1.5 rod thread, and an integrated -S piston magnet for use with CMSG, DMSG, or EMSG sensors.
For real-world sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction and smooth travel. This bore can vertically lift roughly 128 kg with a 2:1 safety margin. The standard TPU seals handle -20 to +70 C, but a Viton H option extends heat resistance up to 150 C for demanding environments.

Where the Airtac SAU Standard Air Cylinder SAU80X15S Is Used
Short-Stroke Stamping
Ideal for compact stamping or riveting heads where a brief 15 mm travel applies the full 2513 N push force to seat a bearing in a tight automated assembly cell.
Heavy Clamping Jig
Provides massive holding pressure for machining fixtures, using the minimal stroke to rapidly clamp heavy steel blocks without consuming valuable machine envelope.
Ejector Mechanism
Functions as a high-impact parts ejector on injection molding lines, using the integrated magnet to trigger a CMSG sensor for precise ejection confirmation.
Is the Airtac SAU Standard Air Cylinder SAU80X15S the Right Cylinder?
When sizing this 80 mm bore, compare it against its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. Choose the SAU80X15S when you need substantial force within a minimal footprint. Because this is a short 15 mm stroke, ensure your mounting uses SC-series accessories like an LB foot or FA flange to absorb any direct impacts. The included -S magnet enables precise end-of-stroke sensing.
Remember that a standard double-acting cylinder drifts when air is removed or a valve centers. The adjustable air cushion only decelerates the piston near the end of travel; it does not act as a brake. If your application requires holding a load vertically, add an external rod lock or a pilot-operated check valve.
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 SAU80X15S FAQ
This 80 mm bore cylinder has a 3/8" port and an M20x1.5 rod thread. It 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.
It is not an ISO 15552 cylinder, but it shares mounting accessories with the AirTAC SC series, such as FA flange and LB foot brackets. The -S suffix indicates a built-in magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly into the barrel profile groove.
