About the Airtac SAU Standard Air Cylinder SAU80X475S
The AirTAC SAU80X475S is a double-acting profile-type cylinder featuring a 475 mm stroke and a 3/8 inch port. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, saving valuable machine space. It delivers a robust 2513 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
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 included -S magnet enables CMSG, DMSG, or EMSG sensor switches directly in the profile groove, while the Viton H seal option extends operating temperatures up to 150 C for high-heat environments.

Where the Airtac SAU Standard Air Cylinder SAU80X475S Is Used
Pallet Diversion
Pushes heavy wooden pallets sideways onto secondary packaging lines using its 2513 N push force at 0.5 MPa without requiring maximum system pressure.
Vertical Material Lift
Raises loaded tote bins weighing up to 128 kg in warehouse automation, relying on external linear guides to support the 475 mm travel distance.
Press Ejection
Ejects formed metal components from stamping presses, utilizing the 28 mm adjustable air cushions to smoothly stop the 80 mm bore at stroke end.
Is the Airtac SAU Standard Air Cylinder SAU80X475S the Right Cylinder?
When sizing this actuator, compare it against adjacent bores: the 63 mm option yields 1559 N push at 0.5 MPa, whereas the 100 mm bore provides 3927 N, helping you match your exact energy requirements. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG electronic positioning switches. You can mount it using AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises.
With a 475 mm stroke, the 25 mm rod is susceptible to bending under lateral stress, so an external guide mechanism is strongly recommended to prevent side-loading damage. Furthermore, the adjustable 28 mm air cushions only decelerate the piston near the end of travel; they do not function as a brake. If your application must hold a vertical load during air loss or valve centering, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 SAU80X475S FAQ
This 80 mm bore cylinder provides 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 features a 25 mm rod, a 3/8 inch port, M20x1.5 rod thread, and operates at speeds between 30-800 mm/s.
No, it is not dimensionally interchangeable with ISO 15552 standards, but it shares mounting accessories with the AirTAC SC series, including LB, FA, FB, CA, and CB brackets. Because this model includes the -S magnet, you can install CMSG, DMSG, or EMSG switches directly into the extruded profile barrel groove.
