Airtac SAU Standard Air Cylinder SAU80X160
The AirTAC Airtac SAU Standard Air Cylinder SAU80X160 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 160mm 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 SAU80X160
The AirTAC SAU80X160 is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is engineered to be physically shorter than an ISO 15552 cylinder of the same 80 mm bore, providing a distinct space advantage in tight machine layouts. It delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, with a 3/8 inch air port and an M20x1.5 rod thread.
For real-world sizing, plan for a safe working load of roughly 1508 N, which accounts for seal friction at 0.5 MPa. Vertically, this translates to lifting about 128 kg 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. Note that because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU80X160 Is Used
Injection Mold Platen Ejection
Drives the ejection plate in plastic injection molding machines, utilizing the 2513 N push force to reliably break and eject heavy finished parts from the mold cavity.
Palletizer Push-Off Arm
Acts as the horizontal push-off actuator in end-of-line palletizing cells, moving stacked cartons onto a wrapping station where the compact profile saves valuable floor space.
Heavy-Duty Stamping Press Feed
Feeds thick gauge sheet metal into a mechanical stamping press, using the 28 mm adjustable air cushions to smoothly decelerate the 160 mm stroke at high cycling speeds.
Is the Airtac SAU Standard Air Cylinder SAU80X160 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm cylinder reduces the 0.5 MPa push force to 1559 N, whereas stepping up to a 100 mm bore increases it to 3927 N. This SAU80X160 model uses the same LB foot, FA/FB flange, and CA/CB clevis mounting accessories as the AirTAC SC series. If your application requires position feedback, you must select the -S magnet variant instead of this base SKU.
Because this unit does not inherently hold its position upon air loss or valve centering—the piston will drift and the cushions only decelerate near stroke end—you should incorporate an external rod lock or a pilot-operated check valve for suspended loads. The 160 mm stroke is well within standard limits, keeping side-load stress manageable without requiring additional guide rails.
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 SAU80X160 FAQ
This 80 mm bore cylinder provides 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. It operates on filtered air at 0.15-1.0 MPa, runs at 30-800 mm/s, and uses a 3/8 inch port.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, accepting LB, FA, FB, CA, and CB mounts. Because this specific SKU does not include the -S magnet, it cannot support CMSG, DMSG, or EMSG magnetic sensors; you must order the -S variant for position sensing.
