About the Airtac SAU Standard Air Cylinder SAU80X55S
The AirTAC SAU80X55S is a double-acting profile-type standard cylinder engineered to be shorter than an ISO 15552 unit of the same bore, saving valuable machine space. It features a 25 mm hard-chrome piston rod, M20x1.5 rod-end thread, and a 3/8 inch air port. Delivering a robust 2513 N of push force at 0.5 MPa, it is built for heavy-duty cycling.
Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly into the extruded barrel groove for precise position detection. For practical sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa to account for seal friction. Alternatively, it can vertically lift about 128 kg with a 2:1 safety margin. 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 SAU80X55S Is Used
Injection Mold Clamping
Provides high clamping thrust for securing injection mold halves, utilizing the compact profile to fit within tight press boundaries.
Pallet Stopper Gate
Acts as a heavy-duty stopper arm on high-throughput packaging lines, using the 55 mm stroke to block loaded pallets reliably.
Press Fit Assembly
Drives bearings into heavy housings on automotive assembly lines, capitalizing on 2513 N of push force at 0.5 MPa.
Is the Airtac SAU Standard Air Cylinder SAU80X55S the Right Cylinder?
When sizing this unit, compare it against its neighbors: the 63 mm bore yields 1559 N of push at 0.5 MPa, while the 100 mm bore provides 3927 N. Choose the 80 mm bore to efficiently handle loads requiring that middle-ground thrust. This model uses the same LB foot, FA/FB flange, and CA/CB clevis mounting accessories as the AirTAC SC series. The integrated -S magnet ensures immediate compatibility with your chosen sensors.
Remember that a standard cylinder will drift if air pressure drops or the valve centers; the adjustable 28 mm air cushions only decelerate the piston near the stroke ends and do not function as a locking brake. To suspend a load safely during an emergency stop, add an external rod lock or a pilot-operated check valve to 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 SAU80X55S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa 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 is 0.15-1.0 MPa, speed is 30-800 mm/s, and it uses a 3/8 inch port.
No, it is a compact profile cylinder that is shorter than an ISO 15552 unit. It shares mounting accessories with the AirTAC SC series, such as LB, FA, FB, CA, and CB brackets. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
