Airtac SAU Standard Air Cylinder SAU80X325
The AirTAC Airtac SAU Standard Air Cylinder SAU80X325 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 325mm 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 SAU80X325
The AirTAC SAU80X325 is a double-acting profile-type cylinder engineered with an extruded aluminum barrel that is physically shorter than an ISO 15552 unit of the same bore. Operating at 0.15-1.0 MPa, it delivers a robust 2513 N push and 2268 N pull at 0.5 MPa, utilizing a 3/8" port and a 25 mm rod with an M20x1.5 thread.
Because seal friction and smooth travel eat into theoretical ratings, plan for a safe working load of about 1508 N at 0.5 MPa. For vertical lifting, this translates to hoisting roughly 128 kg with a 2:1 safety margin. This SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors; for high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAU Standard Air Cylinder SAU80X325 Is Used
Injection Mold Platen Ejection
Drives heavy mold ejection plates over a 325 mm span, utilizing the 2513 N push force to strip dense plastic parts safely without exceeding the 128 kg vertical lift threshold.
Pallet Transfer Pusher
Indexes loaded pallets between processing stations, relying on the SC-series FA flange mount to secure the cylinder while external guides absorb the carton side-load.
Vertical Crate Hoist
Lifts materials to overhead conveyors, where the compact profile barrel saves valuable vertical machine space compared to standard ISO 15552 cylinders of the same bore.
Is the Airtac SAU Standard Air Cylinder SAU80X325 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm unit yields 1559 N push at 0.5 MPa, while moving up to a 100 mm bore provides 3927 N. This model shares its mounting footprint with AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets. At a 325 mm stroke, the 25 mm rod is susceptible to bending under lateral stress, so external guide rails should support the payload.
Note that the adjustable 28 mm air cushions only decelerate the piston near the end of travel and do not function as a brake. If your application must hold a load vertically during air loss or valve centering, the piston will drift; install an external rod lock or a pilot-operated check valve to prevent falling.
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 SAU80X325 FAQ
The SAU80X325 features a 3/8" port and generates 2513 N push and 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; it shares mounting dimensions only with AirTAC SC-series accessories like LB, FA, and CA brackets. Additionally, this specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG magnetic switches.
