Airtac SAU Standard Air Cylinder SAU80X700S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X700S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 700mm 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 SAU80X700S
The AirTAC SAU80X700S is a double-acting profile-type cylinder featuring a 700 mm stroke and a 3/8" port. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, saving valuable machine space. It delivers a robust 2513 N push force at 0.5 MPa, alongside a 2268 N pull force.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction. Vertically, this translates to lifting about 128 kg with a 2:1 safety margin. The included -S magnet enables CMSG, DMSG, or EMSG sensors in the profile groove, and a Viton H seal option extends operation to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X700S Is Used
Pallet Diversion
Pushes heavy pallets across transfer lines using the 2513 N push force at 0.5 MPa, fitting into tight conveyor frames thanks to the compact profile barrel.
Vertical Lift Gate
Raises loading dock gates with a 700 mm stroke, safely lifting around 128 kg vertically when applying a 2:1 safety margin to the 0.5 MPa output.
Injection Mold Ejection
Drives long-stroke ejection pins on large molding presses, relying on the M20x1.5 rod thread and 28 mm adjustable air cushions to soften end-of-travel impacts.
Is the Airtac SAU Standard Air Cylinder SAU80X700S the Right Cylinder?
If you need less force, the 63 mm bore provides 1559 N push at 0.5 MPa; for heavier loads, the 100 mm bore offers 3927 N. This 700 mm stroke requires an external guide to prevent rod bending and absorb side loads. The adjustable air cushion only decelerates the piston near stroke end; it will not hold a load if air is lost. Use an external rod lock or pilot-operated check valve for position holding. Mounting uses AirTAC SC-series accessories like LB foot or FA flange.
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 SAU80X700S FAQ
The 3/8" ported 80 mm bore yields 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
It is not dimensionally interchangeable with ISO 15552 standards, but it shares mounting accessories with the AirTAC SC series. The -S magnet allows CMSG, DMSG, and EMSG switches to fit directly into the barrel groove.
