Airtac SAU Standard Air Cylinder SAU80X800S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X800S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 800mm 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 SAU80X800S
The AirTAC SAU80X800S is a double-acting profile-type cylinder featuring an 80mm bore and an 800mm stroke. Because it uses an extruded aluminum profile barrel, it delivers a shorter overall length than an ISO 15552 cylinder of the same bore, saving valuable machine space. It operates at 30-800 mm/s and provides a robust 2513 N of push force and 2268 N of pull force at 0.5 MPa, with a 3/8" port and an M20x1.5 rod thread.
For practical sizing, plan for a safe working load of about 1508 N (roughly 60% of the 0.5 MPa push rating) to account for friction. Vertically, it lifts about 128 kg with a 2:1 safety margin. The included -S magnet enables CMSG, DMSG, or EMSG switches in the profile groove. If your environment exceeds 70 C, specify the Viton H seal option for 0-150 C operation.

Where the Airtac SAU Standard Air Cylinder SAU80X800S Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets sideways onto secondary packaging lines using its 2513 N push force and 800mm reach.
Vertical Lift Gate
Raises mezzanine safety gates or material shutters, safely lifting loads up to 128 kg thanks to the integrated magnet for position tracking.
Injection Mold Ejection
Drives long-stroke ejection plungers on large molding machinery where the shorter profile barrel keeps the press footprint tight.
Is the Airtac SAU Standard Air Cylinder SAU80X800S the Right Cylinder?
When sizing this unit, the 63mm bore offers 1559 N push at 0.5 MPa, while the 100mm bore yields 3927 N, allowing you to step up or down based on exact force needs. It shares mounting footprint accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis options. Because this is an 800mm stroke, you must use external guides to prevent rod bending and manage side loads over that long extension distance.
Remember that a standard cylinder drifts when air is lost or a valve centers; the adjustable 28mm air cushions only decelerate the piston near the end caps and do not function as a locking brake. To suspend a load safely mid-stroke, 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 SAU80X800S FAQ
This 80mm bore cylinder features a 3/8" port and generates 2513 N push / 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder, but it shares mounting accessories with the AirTAC SC series (LB, FA, FB, CA, CB). The -S suffix means it has a piston magnet for CMSG, DMSG, and EMSG switches in the profile groove.
