Airtac SAU Standard Air Cylinder SAU80X230
The AirTAC Airtac SAU Standard Air Cylinder SAU80X230 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 230mm 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 SAU80X230
The AirTAC SAU80X230 is a double-acting profile-type cylinder featuring an extruded aluminum barrel that is notably shorter than an ISO 15552 cylinder of the same 80 mm bore. 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 and a 25 mm rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction and smooth travel. This translates to lifting roughly 128 kg vertically with a 2:1 safety margin. The unit uses adjustable air cushions at both ends to decelerate the piston near stroke end, and because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU80X230 Is Used
Injection Mold Clamping
Provides 2513 N of push force at 0.5 MPa to secure mid-sized injection mold halves, utilizing the 230 mm stroke to clear the mold area during tooling changes.
Pallet Stopper Gate
Acts as a heavy-duty stopper arm on conveyor lines, safely absorbing the impact of incoming pallets thanks to the 28 mm adjustable air cushions at both ends.
Stamping Press Feed
Drives a metal blank feed mechanism into a stamping press, taking advantage of the compact profile length to fit within tight machine guarding constraints.
Is the Airtac SAU Standard Air Cylinder SAU80X230 the Right Cylinder?
When sizing this 80 mm bore, evaluate your neighbors: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N. This SAU80X230 fits neatly in the middle for medium-heavy machinery. Mounting is straightforward using AirTAC SC-series accessories, including LB foot mounts, FA/FB flanges, and CA/CB clevises.
Remember that a standard cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The air cushion only slows travel at the end of the stroke and acts purely as a deceleration device, never as a locking brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your pneumatic 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 SAU80X230 FAQ
This 80 mm bore cylinder 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 it reaches a theoretical maximum of 513 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder, but it shares the exact same mounting accessories as the AirTAC SC series, such as LB foot, FA/FB flange, and CA/CB clevis brackets. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches.
