Airtac SAU Standard Air Cylinder SAU80X70S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X70S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 70mm 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 SAU80X70S
The AirTAC SAU80X70S is a double-acting profile-type cylinder with a 80 mm bore and 70 mm stroke. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. It delivers a robust 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 includes the -S magnet, it readily accepts CMSG, DMSG, or EMSG switches in the profile groove for position sensing. For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction, which means it can vertically lift roughly 128 kg with a 2:1 safety margin. If your environment exceeds standard temperatures, you can specify the Viton H seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X70S Is Used
Stamping Press Feed
Pushes metal blanks into a forming die using 2513 N of force, relying on the compact profile to fit within tight press guarding.
Pallet Stopper Gate
Acts as a heavy-duty stop for loaded pallets on a conveyor, lifting up to 128 kg vertically to index loads securely.
Heavy Carton Sealing
Drives a sealing head against large shipping cartons, using the 70 mm stroke and 3/8" port for rapid, high-force actuation.
Is the Airtac SAU Standard Air Cylinder SAU80X70S the Right Cylinder?
When sizing this 80 mm bore unit, compare it to its neighbors: a 63 mm bore gives 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. Choose this model when your application requires the 2513 N output and the 70 mm stroke fits your travel requirement. It shares mounting accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis options.
Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the adjustable 28 mm air cushions only decelerate the piston near the end of travel and do not act as a brake. To hold a load securely, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 SAU80X70S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa the push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, and speed is 30-800 mm/s.
The -S suffix means it has a built-in magnet for CMSG, DMSG, and EMSG switches. It is a compact profile cylinder, not an ISO 15552 unit, but it shares the same mounting accessories as the AirTAC SC series for easy integration.
