Airtac SAU Standard Air Cylinder SAU80X260
The AirTAC Airtac SAU Standard Air Cylinder SAU80X260 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 260mm 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 SAU80X260
The AirTAC SAU80X260 is a double-acting profile-type cylinder built around an extruded aluminum barrel. By eliminating external tie rods, it achieves a shorter overall length than an ISO 15552 cylinder of the same 80 mm bore, saving valuable machine space. It delivers a robust 2513 N of push force at 0.5 MPa, utilizing a 25 mm carbon steel rod and a 3/8" port for high flow.
For practical sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa to account for seal friction and smooth travel. Vertically, this translates to lifting about 128 kg with a 2:1 safety margin. The standard TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C. Note that because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU80X260 Is Used
Press Ejection
Ejects formed metal parts from a 100-ton stamping press, using the 2513 N push force to reliably clear heavy dies without slowing the cycle time.
Pallet Diversion
Actuates a heavy-duty diverter arm on a packaging line to route loaded pallets, relying on the compact profile to fit within tight conveyor frame gaps.
Vertical Lift Gate
Raises a 120 kg security gate in a logistics facility, staying safely within the 128 kg vertical lift capacity while benefiting from adjustable end cushions.
Is the Airtac SAU Standard Air Cylinder SAU80X260 the Right Cylinder?
When sizing this 80 mm bore, compare it to its neighbors: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N at the same pressure. This SAU80X260 fits perfectly in the middle for medium-heavy tasks. It shares mounting dimensions with the AirTAC SC series, so you can easily source LB foot brackets, FA/FB flanges, or CA/CB clevises. If your mechanism requires position feedback, you must select the -S magnet variant instead of this base model.
Because air pressure alone cannot maintain a stationary load, this cylinder will drift if air is lost or the valve is centered; the adjustable 28 mm air cushions only decelerate the piston near stroke ends. For vertical or suspended loads, integrate an external rod lock or a pilot-operated check valve. Furthermore, at this 260 mm stroke length, ensure your mechanical guide rails support the load to prevent rod bending and premature seal wear.
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 SAU80X260 FAQ
The 80 mm bore generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N, and the theoretical maximum force is 513 kgf at 1.0 MPa. It uses a 3/8" air port, a 25 mm rod, and features 28 mm adjustable air cushions at both ends.
No, the SAU is not an ISO 15552 cylinder and does not share that footprint. However, it is designed to share mounting accessories with the AirTAC SC series, allowing you to use standard SC LB, FA, FB, CA, and CB brackets. Also, this specific SKU lacks the -S magnet, so it cannot host magnetic sensors.
