Airtac SAU Standard Air Cylinder SAU80X15
The AirTAC Airtac SAU Standard Air Cylinder SAU80X15 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 SAU80X15
The AirTAC SAU80X15 is a double-acting profile-type cylinder engineered for high force in tight machinery envelopes. Its extruded aluminum barrel makes it shorter 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, operating on a 3/8" port with an M20x1.5 rod thread.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For real-world sizing, plan for a safe working load of about 1508 N (60 percent of the 0.5 MPa push figure) to account for seal friction. In a vertical lift scenario with a 2:1 safety margin, it lifts about 128 kg. The standard TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X15 Is Used
Short-Stroke Stamping
Applies 2513 N of clamping force in compact metal stamping presses where a 15 mm stroke secures the workpiece.
Heavy Part Ejection
Ejects dense molded components from tight injection molding cavities using a brief, high-force 15 mm push.
Pneumatic Riveting
Squeezes rivets in automated assembly lines where a short 15 mm stroke and 80 mm bore provide rapid, heavy compression.
Is the Airtac SAU Standard Air Cylinder SAU80X15 the Right Cylinder?
This 80 mm bore sits between the 63 mm class (1559 N push at 0.5 MPa) and the 100 mm class (3927 N push at 0.5 MPa). Choose the SAU80X15 when the 63 mm lacks thrust but the 100 mm is too bulky. The 15 mm stroke is ideal for short clamping or ejecting motions. Since this model has no -S magnet, position sensing is unavailable. The adjustable 28 mm air cushions at both ends only decelerate the piston near stroke end; they do not act as a brake. If your application must hold a load vertically during air loss, add an external rod lock or a pilot-operated check valve to prevent drift.
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 SAU80X15 FAQ
The SAU80X15 features a 3/8" port and an M20x1.5 rod thread. It delivers 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 dimensions with the AirTAC SC series, accepting LB foot, FA/FB flange, and CA/CB clevis accessories. Additionally, this specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG magnetic sensors.
