Airtac SAU Standard Air Cylinder SAU80X80
The AirTAC Airtac SAU Standard Air Cylinder SAU80X80 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 80mm 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 SAU80X80
The AirTAC SAU80X80 is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is purposefully shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, providing a distinct spatial advantage in dense machinery layouts. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, operating via a 3/8 inch port with a 25 mm piston rod.
For practical sizing, plan for a safe working load of roughly 1508 N, which accounts for seal friction at 0.5 MPa. This translates to lifting about 128 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG reed switches. If your application involves high heat, you can specify the Viton H seal option to elevate the operating range from the standard -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X80 Is Used
Injection Mold Clamping
Provides 2513 N of push force at 0.5 MPa to secure mid-sized injection mold halves, utilizing the compact profile to fit within tight press boundaries.
Pallet Stopper Gate
Acts as a heavy-duty stopper arm on conveyor lines, safely arresting pallets weighing up to 128 kg thanks to its robust 80 mm bore and 25 mm rod.
Press Ejection System
Ejects formed metal or plastic components from hydraulic presses, where the 80 mm stroke and high pull force of 2268 N ensure reliable part removal.
Is the Airtac SAU Standard Air Cylinder SAU80X80 the Right Cylinder?
When sizing this 80 mm bore, compare it directly to 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 SAU80X80 when your load falls comfortably between those thresholds. Keep in mind that a standard cylinder drifts if air pressure drops or the valve centers; the adjustable 28 mm air cushions only decelerate the piston near stroke end and do not function as a braking lock. For suspended loads, integrate an external pilot-operated check valve or a rod lock.
Mounting hardware is fully compatible with AirTAC SC-series accessories, including LB foot mounts, FA/FB flanges, and CA/CB clevises. You can also utilize I, Y, F, or U knuckles at the rod end. Since this configuration omits the -S magnet, position sensing is not supported out of the box.
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 SAU80X80 FAQ
The SAU80X80 features a 3/8 inch port and generates a push force of 2513 N and a pull force of 2268 N 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.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, accepting LB, FA, FB, CA, and CB brackets. Additionally, this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG sensors.
