Airtac SAU Standard Air Cylinder SAU100X350
The AirTAC Airtac SAU Standard Air Cylinder SAU100X350 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 SAU100X350
The AirTAC SAU100X350 is a double-acting profile-type cylinder featuring a 100 mm bore and 350 mm stroke. Built with an extruded aluminum barrel, it provides substantial force with 3927 N push and 3681 N pull at 0.5 MPa, operating on a 1/2" port. Its extruded profile design is physically shorter than an ISO 15552 cylinder of the same bore, offering a distinct space-saving advantage in tight machinery layouts.
For practical sizing, plan for a safe working load of about 2356 N at 0.5 MPa, accounting for seal friction and smooth travel. This translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this to 150 C. Note that this specific SKU lacks a magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic sensors.

Where the Airtac SAU Standard Air Cylinder SAU100X350 Is Used
Heavy Stamping Press
Drives a 200 kg upper die assembly in an automotive stamping press, utilizing the 3927 N push force at 0.5 MPa to form sheet metal reliably.
Pallet Dispenser
Pushes empty pallets into a high-speed packaging line, where the compact profile length prevents interference with adjacent conveyor structures.
Injection Mold Ejection
Actuates a heavy ejection plate in a plastic injection molding machine, requiring the robust 25 mm carbon steel rod and M20x1.5 thread for secure coupling.
Is the Airtac SAU Standard Air Cylinder SAU100X350 the Right Cylinder?
When sizing this 100 mm bore unit, compare it to neighboring bores: a 63 mm cylinder yields 1559 N push at 0.5 MPa, while the 100 mm provides 3927 N. If you need even more power, you are at the top of the SAU range. Mounting is straightforward using AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets. Because this 350 mm stroke is substantial, use external guides to prevent rod bending and premature seal wear under heavy lateral loads.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the adjustable 29 mm air cushions at both ends only decelerate the piston near stroke end and do not function as a locking brake. To suspend a load safely during an emergency stop or pressure drop, install an external rod lock or a pilot-operated check valve in the pneumatic circuit.
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 SAU100X350 FAQ
This 100 mm bore cylinder features a 1/2" air port and a 25 mm rod with an M20x1.5 thread. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa, the push force is 5497 N, and the theoretical maximum force is 801 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 brackets. Additionally, because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic sensors.
