Airtac SAU Standard Air Cylinder SAU80X65S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X65S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 65mm 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 SAU80X65S
The AirTAC SAU80X65S is a double-acting profile-type cylinder engineered to deliver high force in tight machine envelopes. It is purposefully shorter than an ISO 15552 cylinder of the same bore, yielding a compact footprint without sacrificing power. Sharing mounting accessories with the AirTAC SC series, it integrates easily using LB foot, FA/FB flange, or CA/CB clevis brackets. It pushes with 2513 N and pulls with 2268 N at 0.5 MPa, operating at speeds of 30-800 mm/s through its 3/8" port.
For real-world sizing, plan for a safe working load of about 1508 N (roughly 60% of the 0.5 MPa push figure) to account for seal friction and smooth travel. This translates to lifting about 128 kg vertically with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly into the barrel profile for position sensing. If your environment exceeds the standard -20 to +70 C range, specifying the Viton H seal option extends thermal capability up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X65S Is Used
Stamping Press Feeders
Drives heavy material grippers in automated press lines, utilizing the 2513 N push force to advance thick metal sheets reliably through progressive dies.
Pallet Handling Pushers
Shoves loaded pallets transversely onto accumulation conveyors, where the compact profile length prevents interference with adjacent guarding in dense logistics cells.
Heavy Carton Sealing
Actuates large format case erectors, applying consistent pressure to fold and secure oversized corrugated cartons using the 2268 N pull force.
Is the Airtac SAU Standard Air Cylinder SAU80X65S the Right Cylinder?
When sizing this 80 mm bore, compare it to adjacent options to match your load. Stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. The SAU80X65S sits comfortably for medium-heavy tasks. Note that a standard double-acting cylinder drifts when air is lost or the valve is centered; the adjustable 28 mm air cushions only decelerate the piston near stroke end and do not act as a brake. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve. The included magnet (-S) pairs perfectly with CMSG/DMSG/EMSG sensors, and you can utilize I, Y, F, or U knuckles for versatile rod connections.
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 SAU80X65S FAQ
The 80 mm bore uses a 3/8" port and M20x1.5 rod thread. It delivers 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 at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
You cannot use ISO 15552 brackets, as the SAU is a distinct compact profile cylinder. It shares mounting accessories only with the AirTAC SC series (LB, FA, FB, CA, CB). The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors that fit directly into the barrel groove.
