Airtac SAU Standard Air Cylinder SAU80X500S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X500S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 500mm 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 SAU80X500S
The AirTAC SAU80X500S is a double-acting profile-type cylinder featuring a 500 mm stroke and an extruded aluminum barrel with an integrated sensor groove. Because its overall length is shorter than an ISO 15552 cylinder of the same bore, it provides a significant space advantage in tight machine layouts. It operates at 30-800 mm/s, generating 2513 N of push force and 2268 N of pull force at 0.5 MPa, with a 3/8" port and a 28 mm adjustable air cushion at both ends.
For practical sizing, plan for a safe working load of roughly 1508 N—about 60% of the 0.5 MPa push rating—to account for seal friction and smooth travel. This translates to lifting about 128 kg vertically with a 2:1 safety margin. The included -S piston magnet enables CMSG, DMSG, or EMSG electronic switches for position detection, and a Viton H seal option extends the operating temperature from -20...+70 C up to 0-150 C for hot environments.

Where the Airtac SAU Standard Air Cylinder SAU80X500S Is Used
Pallet Diversion
Actuates a 500 mm pusher arm to redirect heavy pallets between parallel conveyor lines, utilizing the 2513 N push force to overcome sliding friction.
Vertical Lift Gate
Raises and lowers a 120 kg material handling gate, relying on the 128 kg safe vertical lift capacity to ensure smooth, counterweighted operation.
Injection Mold Ejection
Drives a long-stroke ejection mechanism to clear large molded parts from a press, taking advantage of the compact profile to fit within tight machine columns.
Is the Airtac SAU Standard Air Cylinder SAU80X500S the Right Cylinder?
When sizing this unit, compare it against adjacent bores: the 63 mm version offers 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. This 80 mm model fits perfectly in the middle, yielding 2513 N at 0.5 MPa and a theoretical maximum of 513 kgf at 1.0 MPa. It shares its mounting footprint with AirTAC SC-series accessories, so you can use LB foot brackets, FA/FB flanges, CA/CB clevises, or I/Y/F/U rod knuckles. Because this SKU includes the -S magnet, it is fully ready for CMSG/DMSG/EMSG sensor switches.
With a 500 mm stroke, the M20x1.5 rod is susceptible to bending under lateral stress; always use an external guide rail to prevent side loads and premature seal wear. Additionally, the standard adjustable air cushion only decelerates the piston near the stroke ends and does not act as a brake. If your application must hold a vertical load when air is lost or the valve is centered, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 SAU80X500S FAQ
The 80 mm bore yields 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. The air port size is 3/8".
No, it is not dimensionally interchangeable with ISO 15552 cylinders, but it shares mounting accessories with the AirTAC SC series (LB, FA, FB, CA, CB). Because this model includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly into the profile barrel groove.
