Airtac SAU Standard Air Cylinder SAU100X230
The AirTAC Airtac SAU Standard Air Cylinder SAU100X230 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 230mm 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 SAU100X230
The AirTAC SAU100X230 is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Its extruded aluminium barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space without sacrificing power. The unit features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at both ends for smooth end-of-stroke deceleration.
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 equates to lifting roughly 200 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For high-temperature environments up to 150 C, you can specify the Viton H seal option instead of the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU100X230 Is Used
Injection Moulding Extraction
Provides the robust 3927 N push force needed to pull heavy plastic parts from moulds, while the 230 mm stroke handles short ejection distances efficiently.
Pallet Positioning Stops
Acts as a heavy-duty stopper block on conveyor lines, absorbing the impact of incoming pallets using its 29 mm adjustable air cushions.
Press Ejection Systems
Ejects dense stamped metal components from press beds, utilising the compact profile length to fit within tight machine tool footprints.
Is the Airtac SAU Standard Air Cylinder SAU100X230 the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against neighbouring bores. If 3927 N at 0.5 MPa is excessive, the 80 mm bore provides 2513 N. If you need more power, this is the largest standard SAU size, offering a theoretical maximum of 801 kgf at 1.0 MPa. Mount this cylinder using AirTAC SC-series accessories, such as LB foot brackets, FA/FB flanges, or CA/CB clevises.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred; the air cushion only decelerates the piston near the end of the stroke and does not act as a brake. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve. Since this 230 mm stroke is under 300 mm, severe rod bending is less of a concern, but always ensure the load is axially aligned to prevent premature seal wear.
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 SAU100X230 FAQ
This 100 mm bore cylinder has a 1/2 inch port and an M20x1.5 rod 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 and shares its mounting dimensions only with the AirTAC SC series (using LB, FA, FB, CA, CB brackets). Additionally, because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.
