Airtac SAU Standard Air Cylinder SAU80X290
The AirTAC Airtac SAU Standard Air Cylinder SAU80X290 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 290mm 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 SAU80X290
The AirTAC SAU80X290 is a double-acting profile-type standard cylinder featuring a 80 mm bore and 290 mm stroke. Its extruded aluminium barrel with integrated sensor groove is engineered to be shorter and more compact than an ISO 15552 cylinder of the same bore, offering a distinct space advantage in tight machine 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" port and a 25 mm carbon steel rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of roughly 1508 N, which accounts for seal friction at 0.5 MPa rather than relying on the absolute maximum. This translates to lifting about 128 kg vertically with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, but a Viton H option extends this to 0-150 C for high-heat environments. Note that because this specific SKU lacks the -S magnet suffix, it cannot host CMSG, DMSG, or EMSG reed switches.

Where the Airtac SAU Standard Air Cylinder SAU80X290 Is Used
Injection Mold Clamping
Provides high clamping force for securing injection mold halves, utilizing the 2513 N push capacity within a compact machinery footprint.
Pallet Lift Stations
Raises heavy pallets in distribution hubs, safely lifting loads around 128 kg vertically while benefiting from the space-saving profile design.
Heavy Package Diverters
Actuates heavy-duty routing gates on conveyor lines, relying on the 2268 N pull force to retract diverter arms under significant friction.
Is the Airtac SAU Standard Air Cylinder SAU80X290 the Right Cylinder?
When sizing this actuator, compare its output against adjacent bores: stepping down to a 63 mm bore yields 1559 N of push force at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. If your application requires position feedback, you must select the -S magnet variant, as this base configuration cannot accept sensors. Mounting hardware is fully compatible with AirTAC SC-series accessories, including LB foot mounts, FA/FB flanges, and CA/CB clevises.
Keep in mind that a standard pneumatic cylinder drifts when air pressure is lost or the valve is centered; the adjustable 28 mm air cushions at both ends only decelerate the piston near stroke end and do not function as a braking mechanism. For securing a vertical load, integrate an external rod lock or a pilot-operated check valve. Additionally, with a 290 mm stroke, ensure adequate guiding to prevent rod bending and manage side loads effectively.
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 SAU80X290 FAQ
This 80 mm bore model features a 3/8" 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, though it is more compact and shares mounting dimensions with the AirTAC SC series (LB, FA, FB, CA, CB). Because this specific SKU lacks the -S suffix, it has no magnet and cannot accept CMSG, DMSG, or EMSG sensors.
