Airtac SAU Standard Air Cylinder SAU80X135
The AirTAC Airtac SAU Standard Air Cylinder SAU80X135 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 135mm 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 SAU80X135
The AirTAC SAU80X135 is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is purposefully shorter than an ISO 15552 cylinder of the same 80 mm bore, providing a space advantage in compact machinery. It delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, operating on a 3/8 inch port with a 25 mm piston rod.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa, accounting for seal friction and smooth travel. This translates to lifting roughly 128 kg vertically with a 2:1 safety margin. The unit includes adjustable air cushions at both ends to decelerate the piston near stroke end. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU80X135 Is Used
Injection Mold Clamping
Provides 2513 N of push force at 0.5 MPa to secure mid-sized injection mold halves, utilizing the 135 mm stroke to clear the mold during part ejection.
Package Diverting Arm
Acts as a compact diverter on a packaging line, extending 135 mm to push heavy cartons onto a secondary track without consuming excessive frame length.
Pallet Stopper Gate
Functions as a robust stop gate on a roller conveyor, using its 128 kg vertical lift equivalent to halt loaded pallets before a wrapping station.
Is the Airtac SAU Standard Air Cylinder SAU80X135 the Right Cylinder?
When sizing this 80 mm bore, compare it to adjacent options: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. This SAU80X135 strikes a balance for medium-heavy loads. It shares mounting accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis brackets. A rod knuckle (I, Y, F, or U) can also be fitted.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. The adjustable cushion only slows travel at the end of the stroke and does not act as a brake. For suspended or vertical loads that must remain in place during air loss, install 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 SAU80X135 FAQ
The SAU80X135 has an 80 mm bore and uses a 3/8 inch port. The force output is 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 you can use SC-series LB, FA, FB, CA, and CB accessories. Additionally, this specific SKU does not have a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
