Airtac SAU Standard Air Cylinder SAU80X225
The AirTAC Airtac SAU Standard Air Cylinder SAU80X225 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 225mm 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 SAU80X225
The AirTAC SAU80X225 is a double-acting profile-type cylinder built with an extruded aluminum barrel. It is engineered to be physically shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, providing a valuable space advantage in tight machine layouts. It delivers a robust 2513 N of push force and 2268 N of pull force at 0.5 MPa, operating efficiently at speeds of 30-800 mm/s through its 3/8" port.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa, accounting for seal friction and smooth travel rather than the raw rated output. This translates to lifting roughly 128 kg vertically with a 2:1 safety margin. The unit features a 25 mm carbon steel rod with an M20x1.5 thread, adjustable 28 mm air cushions at both ends to decelerate the piston near stroke end, and shares mounting accessories with the AirTAC SC series. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU80X225 Is Used
Injection Mold Ejection
Drives the ejection plate on a 150-ton injection molding machine, utilizing the 2513 N push force to reliably strip dense plastic parts from the tool cavity.
Pallet Diverter Arm
Actuates a heavy-duty diverter arm on a packaging conveyor, using the 225 mm stroke to push loaded pallets onto a secondary routing track.
Vertical Lift Gate
Raises and lowers a 100 kg security gate on a warehouse dock, safely operating well within the 128 kg vertical lift capacity at 0.5 MPa.
Is the Airtac SAU Standard Air Cylinder SAU80X225 the Right Cylinder?
When sizing this 80 mm bore, compare it against its neighbors: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. Choose the SAU80X225 when your application requires that middle-ground 2513 N thrust. Note that a plain cylinder does not hold its load if air is lost or the valve is centered; the piston will drift, and the cushion only decelerates at stroke end. For a suspended load, add an external rod lock or a pilot-operated check valve. Since this is a non-magnetized model, position sensing is not possible. At 225 mm stroke, side loads are moderate, but ensuring proper alignment with SC-series foot or flange mounts will maximize rod seal life.
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 SAU80X225 FAQ
The SAU80X225 has a 3/8" air port. It 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.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, so use SC-series LB, FA, or CA brackets. Additionally, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
