Airtac SAU Standard Air Cylinder SAU80X350S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X350S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 350mm 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 SAU80X350S
The AirTAC SAU80X350S is a double-acting profile-type cylinder featuring a 3/8" port, a 25 mm piston rod, and an M20x1.5 rod-end thread. It delivers a robust 2513 N of push force and 2268 N of pull force at 0.5 MPa. Its extruded aluminum barrel with an integrated sensor groove makes it shorter and more compact than an ISO 15552 cylinder of the same bore, providing a distinct space advantage in dense machinery layouts.
Equipped with a built-in magnet (-S), this unit readily supports CMSG, DMSG, or EMSG electronic switches for position sensing. 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, or expect it to lift about 128 kg vertically with a 2:1 safety margin. The standard TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X350S Is Used
Heavy Package Diversion
Handles large cartons on logistics lines by pushing heavy parcels at 30-800 mm/s using its 2513 N push capacity.
Injection Mold Ejection
Ejects dense plastic parts from molding machinery where the shorter profile saves valuable machine footprint.
Pallet Positioning
Shifts loaded pallets laterally with a safe working load of 1508 N, relying on external guides for the 350 mm stroke.
Is the Airtac SAU Standard Air Cylinder SAU80X350S 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, whereas a 100 mm bore provides 3927 N. This model includes the -S magnet for direct sensor groove compatibility. Because the 350 mm stroke is substantial, incorporate external guide rails to prevent rod bending and absorb side loads. Note that the adjustable 28 mm air cushions only decelerate the piston near stroke end; they do not function as a brake. If your application must hold a load vertically during air loss, install an external rod lock or a pilot-operated check valve, as a standard cylinder will drift.
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 SAU80X350S FAQ
The 80 mm bore features a 3/8" port and delivers 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, though it is more compact. It shares mounting dimensions specifically with the AirTAC SC series, accepting LB foot, FA/FB flange, and CA/CB clevis brackets.
