Airtac SAU Standard Air Cylinder SAU100X350S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X350S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 350mm stroke, 1/2" 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 SAU100X350S
The AirTAC SAU100X350S is a double-acting profile-type cylinder featuring a 100 mm bore and 350 mm stroke. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. It delivers a robust 3927 N push and 3681 pull at 0.5 MPa, utilizing a 1/2 inch port and an M20x1.5 rod thread.
For real-world sizing, plan for a safe working load of roughly 2356 N at 0.5 MPa to account for seal friction and smooth travel. This translates to lifting about 200 kg vertically with a 2:1 safety margin. The included -S magnet enables CMSG, DMSG, or EMSG sensor switches in the profile groove, while the standard TPU seals handle -20 to +70 C (a Viton H option extends this to 150 C).

Where the Airtac SAU Standard Air Cylinder SAU100X350S Is Used
Heavy Stamping Press
Drives heavy tooling dies in an automotive stamping line, utilizing the 3927 N push force to form thick steel components reliably.
Pallet Dispenser
Pushes empty wooden pallets into a packaging conveyor, where the 350 mm stroke provides the exact travel needed to index one unit at a time.
Injection Mold Ejector
Ejects large molded plastic bins from a press, using the integrated magnet and DMSG sensor to confirm full retraction before the mold closes.
Is the Airtac SAU Standard Air Cylinder SAU100X350S the Right Cylinder?
When sizing this 100 mm bore unit, consider stepping down to the 80 mm bore if your application only requires 2513 N push at 0.5 MPa, or utilize this model when the 80 mm falls short. Because the 350 mm stroke is substantial, always use an external guide to prevent rod bending and side-load damage. The piston drifts if air is lost or the valve is centered, as the air cushions only decelerate the piston near stroke end and do not act as a brake. For secure load holding, install an external rod lock or a pilot-operated check valve. Mounting is straightforward using AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets.
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 SAU100X350S FAQ
This 100 mm bore cylinder provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. It features a 1/2 inch port, an M20x1.5 rod thread, and operates at speeds between 30-800 mm/s.
It is not an ISO 15552 cylinder, but it is shorter and shares mounting dimensions with the AirTAC SC series, so you can use SC-series LB, FA, FB, CA, and CB brackets. Because this model includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly into the barrel groove.
