Airtac SAU Standard Air Cylinder SAU80X200S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X200S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 200mm 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 SAU80X200S
The AirTAC SAU80X200S is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is purposefully shorter than an ISO 15552 cylinder of the same bore, yielding a space advantage in dense machinery layouts. Delivering a robust 2513 N push force at 0.5 MPa, it utilizes a 3/8" port and a 25 mm piston rod with an M20x1.5 thread.
Because this SKU includes the -S magnet, it readily accepts CMSG, DMSG, or EMSG switches directly in the profile groove for precise position detection. For practical sizing, plan for a safe working load of roughly 1508 N, which accounts for seal friction and smooth travel. In a vertical lift scenario with a 2:1 safety margin, it can lift about 128 kg. If your environment exceeds standard limits, the Viton H seal option elevates the operating temperature range to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X200S Is Used
Injection Mold Clamping
Provides reliable 2513 N clamping force on mid-sized injection molding platens where a shorter overall envelope prevents interference with the safety gate.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop gate in high-throughput logistics conveyors, using the integrated magnet to confirm gate position for the PLC.
Case Erector Forming
Drives the folding mechanism on automated corrugated box erectors, delivering enough thrust to square heavy cardboard blanks at high cycle rates.
Is the Airtac SAU Standard Air Cylinder SAU80X200S the Right Cylinder?
When sizing this actuator, compare its output against adjacent bores: the 63 mm variant provides 1559 N push at 0.5 MPa, while the 100 mm option steps up to 3927 N. If air pressure drops or the valve is centered, the piston will drift because the standard air cushion only decelerates the rod near stroke end rather than locking it; integrate a pilot-operated check valve or external rod lock to sustain a suspended mass. Mounting hardware matches the AirTAC SC series, allowing you to use standard LB foot brackets, FA/FB flanges, or CA/CB clevises. The 200 mm stroke is well within standard limits, keeping the assembly compact without requiring extended guide rods to counter side-load bending.
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 SAU80X200S FAQ
This 80 mm bore cylinder features a 3/8" port and generates 2513 N push and 2268 N pull 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.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore while sharing mounting dimensions with the AirTAC SC series. The -S suffix denotes a built-in piston magnet, allowing you to drop CMSG, DMSG, or EMSG switches directly into the barrel groove.
