Airtac SAU Standard Air Cylinder SAU100X230S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X230S 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 SAU100X230S
The AirTAC SAU100X230S is a double-acting profile-type cylinder with a 100mm bore and 230mm 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 push force of 3927 N at 0.5 MPa, placing it in the heavy-duty class for pneumatic actuation.
This unit includes a built-in piston magnet (-S) for direct mounting of CMSG, DMSG, or EMSG sensors along the profile groove. It features a 1/2 inch air port, an M20x1.5 rod thread, and 29mm adjustable air cushions at both ends. For practical sizing, plan for a safe working load of about 2356 N (roughly 60% of the 0.5 MPa push figure) to account for friction. Vertically, it lifts about 200 kg with a 2:1 safety margin.

Where the Airtac SAU Standard Air Cylinder SAU100X230S Is Used
Heavy Stamping Press
Drives a heavy stamping die requiring 3927 N of push force at 0.5 MPa, utilizing the 29mm adjustable cushion to halt the 230mm stroke smoothly.
Pallet Handling Gate
Actuates a large diverter gate on a packaging line, where the compact profile length frees up conveyor frame space without sacrificing lifting power.
Vertical Lift Arm
Raises a 200 kg materials tote using a 2:1 leverage margin, relying on the M20x1.5 rod and 1/2 inch port for high-flow pneumatic response.
Is the Airtac SAU Standard Air Cylinder SAU100X230S the Right Cylinder?
When sizing this 100mm bore actuator, compare it against its neighbors: a 63mm bore yields 1559 N push at 0.5 MPa, while stepping up to the 100mm provides 3927 N. Since this is the largest standard SAU bore, exceeding its capacity requires a multi-cylinder setup. The 230mm stroke is well within the 1500mm maximum, avoiding rod-bending concerns.
Because the SAU100X230S features the -S magnet, it is fully ready for CMSG/DMSG/EMSG electronic or reed switches. Mounting relies on AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises. Remember that standard air cushions only decelerate the piston near stroke end; they do not act as a brake. To prevent drift from gravity or air loss, install 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 SAU100X230S FAQ
The 100mm bore yields 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. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a 1/2 inch air port.
No, it is not dimensionally interchangeable with ISO 15552 brackets; you must use AirTAC SC-series accessories like LB, FA, or CA mounts. However, the -S magnet in this model allows direct fitting of CMSG, DMSG, or EMSG switches into the barrel groove.
