Airtac SAU Standard Air Cylinder SAU80X160S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X160S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 160mm 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 SAU80X160S
The AirTAC SAU80X160S is a double-acting profile-type cylinder engineered for heavy automation. Its extruded aluminum barrel makes it shorter and more compact than a standard ISO 15552 unit of the same bore, saving valuable machine space. 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 a 25 mm rod and M20x1.5 thread.
For practical sizing, plan for a safe working load of about 1508 N (60% of the 0.5 MPa push force) to account for seal friction. Vertically, it lifts about 128 kg with a 2:1 safety margin. The -S suffix means a piston magnet is built in, allowing CMSG, DMSG, or EMSG switches to clip directly into the profile groove for position sensing. If your environment exceeds 70 C, specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X160S Is Used
Press Fit Assembly
Drives bearings into heavy cast housings on an automotive line, utilizing the 2513 N push force to seat parts accurately within a compact machinery envelope.
Pallet Dispenser
Pushes empty pallets into a high-speed conveyor lane, where the shorter profile length prevents interference with adjacent transfer rails.
Heavy Box Flap Folder
Folds thick cardboard flaps on large industrial cartons, using the 160 mm stroke and integrated magnet for precise mid-stroke position confirmation.
Is the Airtac SAU Standard Air Cylinder SAU80X160S the Right Cylinder?
When sizing this 80 mm bore, compare it to its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. Choose this model when your application requires roughly 2513 N of push force within a tight footprint. The 160 mm stroke is standard, but always guide the load to prevent rod bending. Mounting is straightforward using AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets.
Remember that a standard cylinder drifts when air is lost or the valve is centered; the adjustable 28 mm air cushions only decelerate the piston near stroke end and do not function as a brake. To hold a load securely, install 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 SAU80X160S FAQ
This 80 mm bore cylinder has a 25 mm rod, M20x1.5 thread, and a 3/8" port. It delivers 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 max of 513 kgf at 1.0 MPa. It features 28 mm adjustable air cushions at both ends and operates at 30-800 mm/s.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, so you can use SC LB, FA, FB, CA, and CB accessories. The -S suffix indicates a built-in magnet, allowing CMSG, DMSG, or EMSG switches to fit directly into the barrel profile groove for sensing.
