Airtac SAU Standard Air Cylinder SAU80X30S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X30S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 30mm 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 SAU80X30S
The AirTAC SAU80X30S is a double-acting profile-type cylinder engineered for tight machinery spaces. Its extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same 80 mm bore, while its 30 mm stroke provides rapid, high-force movement in confined envelopes. Operating at 0.15-1.0 MPa, it generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. The unit features a 3/8" port, an M20x1.5 rod thread, and adjustable air cushions of 28 mm at both ends.
Because seal friction and smooth travel reduce actual output, you should plan for a safe working load of about 1508 N at 0.5 MPa. For vertical applications, this translates to lifting roughly 128 kg with a 2:1 safety margin. The built-in -S piston magnet allows you to mount CMSG, DMSG, or EMSG sensors directly into the barrel groove for precise end-of-stroke detection. If your environment exceeds the standard -20 to +70 C range, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X30S Is Used
Stamping Press Ejection
Uses the 2513 N push force at 0.5 MPa to knock heavy stamped metal panels out of a press die within a very short 30 mm travel distance.
Pallet Stopper Gate
Acts as a high-strength physical stop barrier on a heavy-duty packaging conveyor, raising quickly to halt 100+ kg pallets.
Heavy Carton Sealing
Briefly clamps large, heavy shipping cartons in place at a sealing station, utilizing the compact profile to fit within dense conveyor framework.
Is the Airtac SAU Standard Air Cylinder SAU80X30S the Right Cylinder?
When sizing this model, compare it against its neighbors: stepping down to a 63 mm bore yields 1559 N of push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. The SAU80X30S fits perfectly when you need that middle ground of 2513 N within a minimal 30 mm stroke. It shares its mounting footprint with AirTAC SC-series accessories, so you can use standard LB foot brackets, FA/FB flanges, or CA/CB clevises. Keep in mind that a standard cylinder drifts if air pressure drops or the valve is centered; the adjustable cushion only decelerates the piston near the end of stroke rather than locking it. To suspend a load safely during an emergency stop, integrate 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 SAU80X30S FAQ
The SAU80X30S 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, a push force of 3518 N at 0.7 MPa, and a theoretical maximum force of 513 kgf at 1.0 MPa.
Yes, the S in SAU80X30S indicates a built-in piston magnet. This allows you to install CMSG, DMSG, or EMSG electronic or reed switches directly into the sensor groove on the extruded aluminum profile barrel.
