Airtac SAU Standard Air Cylinder SAU80X65
The AirTAC Airtac SAU Standard Air Cylinder SAU80X65 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 SAU80X65
The AirTAC SAU80X65 is a double-acting profile-type cylinder featuring an extruded aluminum barrel that is physically shorter than an ISO 15552 cylinder of the same 80 mm bore. It provides a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, operating at speeds of 30-800 mm/s. The unit incorporates a 3/8" air port, an M20x1.5 rod-end thread, and a 28 mm adjustable air cushion at both ends to smooth out stroke deceleration.
Because this specific SKU lacks the -S suffix, it cannot accept magnetic switches and is not suited for position sensing. For real-world sizing, plan for a safe working load of roughly 1508 N (about 60% of the 0.5 MPa push figure) to account for seal friction. Alternatively, you can expect it to lift about 128 kg vertically with a 2:1 safety margin. If your environment exceeds standard -20 to +70 C limits, a Viton H high-temperature seal option extends operation up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X65 Is Used
Injection Mold Clamping
Provides 2513 N of push force at 0.5 MPa to secure mid-sized injection mold halves within a compact machinery frame.
Package Diverting
Drives a heavy-duty diverter arm on a logistics conveyor, utilizing the 65 mm stroke to reroute parcels efficiently.
Pallet Positioning
Indexes loaded pallets on a roller conveyor by pushing against the pallet side, leveraging the 128 kg vertical lift equivalent.
Is the Airtac SAU Standard Air Cylinder SAU80X65 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, while a 100 mm bore provides 3927 N. Choose the SAU80X65 when your application requires moderate thrust in a compact footprint. Mounting is straightforward using AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises. Remember that a standard cylinder drifts if air pressure is lost or the valve is centered; the air cushion only decelerates the piston near the end of stroke and does not act as a braking mechanism. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve.
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 SAU80X65 FAQ
The SAU80X65 features a 3/8" air port and generates 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.
No, this specific SKU does not include the -S magnet option, so it cannot accommodate CMSG, DMSG, or EMSG magnetic switches. Mounting hardware is compatible with AirTAC SC-series accessories.
