Airtac SAU Standard Air Cylinder SAU80X230S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X230S 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 SAU80X230S
The AirTAC SAU80X230S is a double-acting profile-type cylinder with a 230 mm stroke and a built-in magnet for CMSG, DMSG, or EMSG switches. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, saving valuable machine space. It delivers a robust 2513 N push and 2268 N pull at 0.5 MPa, operating at speeds between 30 and 800 mm/s.
Featuring a 25 mm carbon steel rod with M20x1.5 threading and a 3/8" port, this unit uses adjustable air cushions at both ends to manage piston deceleration. For practical sizing, plan for a safe working load of about 1508 N (roughly 60% of the 0.5 MPa push force) to account for seal friction. This translates to lifting about 128 kg vertically with a 2:1 safety margin. You can also specify high-temperature Viton H seals to push the operating range from -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X230S Is Used
Injection Mold Extraction
Provides the 2513 N push force needed to pull heavy molded parts from deep dies, using the 230 mm stroke to clear the press platen safely.
Palletized Goods Handling
Drives heavy-duty transfer arms in automated storage systems, moving loaded pallets laterally without requiring a full ISO 15552 footprint.
Heavy Press Feeders
Pushes thick metal blanks into forming presses, utilizing the 28 mm adjustable air cushions to prevent end-of-stroke shock on rapid cycles.
Is the Airtac SAU Standard Air Cylinder SAU80X230S the Right Cylinder?
When sizing this 80 mm bore, compare it against its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. The SAU80X230S hits a strong middle ground for heavy-duty handling. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG sensor integration along the profile groove. Mounting hardware is fully compatible with AirTAC SC-series accessories, including LB foot mounts, FA/FB flanges, and CA/CB clevises.
Note that a standard double-acting cylinder drifts if air pressure drops or the valve is centered; the adjustable cushion only slows travel near the stroke ends and does not act as a brake. To suspend a load securely during an air loss event, install an external rod lock or a pilot-operated check valve.
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 SAU80X230S FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At 0.7 MPa it pushes 3518 N, and at 0.9 MPa it pushes 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder. The SAU is a compact profile cylinder, meaning it is physically shorter than an ISO equivalent. You must use AirTAC SC-series mounting accessories like LB foot, FA/FB flange, or CA/CB clevis brackets.
