Airtac SAU Standard Air Cylinder SAU80X475
The AirTAC Airtac SAU Standard Air Cylinder SAU80X475 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 475mm 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 SAU80X475
The AirTAC SAU80X475 is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is purposefully shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, yielding a space win in tight machine layouts. It delivers a robust push force of 2513 N and a pull of 2268 N at 0.5 MPa, utilizing a 3/8 inch port and an M20x1.5 rod thread.
For real-world sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa to account for seal friction and smooth travel. This translates to lifting about 128 kg vertically with a 2:1 safety margin. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. If your environment exceeds standard -20 to +70 C limits, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X475 Is Used
Injection Mold Ejection
Drives heavy mold ejection plates over the 475 mm travel, utilizing the 2513 N push force to reliably strip dense plastic parts from deep cavities.
Pallet Diverting
Pushes loaded pallets laterally on a packaging line where the compact profile length prevents interference with adjacent guarding.
Vertical Gate Lifting
Raises and lowers heavy security gates on automated storage systems, safely managing loads near the 128 kg vertical lift threshold.
Is the Airtac SAU Standard Air Cylinder SAU80X475 the Right Cylinder?
When sizing this actuator, evaluate the neighboring bores: the 63 mm variant provides 1559 N push at 0.5 MPa, while the 100 mm option steps up to 3927 N. Because this 475 mm stroke is substantial, you must support the load with external guides to prevent rod bending and premature seal wear from side loads. Mounting is straightforward using AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets. Remember that a standard cylinder drifts when air is lost or a valve centers; the adjustable 28 mm air cushions only decelerate the piston near stroke ends. To maintain vertical position, 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 SAU80X475 FAQ
This 80 mm bore model uses a 3/8 inch port and an M20x1.5 rod thread. It 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.
It is not an ISO 15552 cylinder, so you must use AirTAC SC-series mounting accessories like LB, FA, FB, CA, or CB brackets. Additionally, this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches.
