Airtac SAU Standard Air Cylinder SAU100X140
The AirTAC Airtac SAU Standard Air Cylinder SAU100X140 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 140mm 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 SAU100X140
The AirTAC SAU100X140 is a double-acting profile-type cylinder featuring a 100 mm bore and 140 mm stroke. It utilizes an extruded aluminum barrel with an integrated sensor groove and adjustable air cushions at both ends. Designed to be physically shorter and more compact than an ISO 15552 cylinder of the same bore, it provides substantial force in tight machine envelopes. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, with a 1/2" air port and an M20x1.5 rod thread.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In a vertical lift scenario, this equates to lifting roughly 200 kg with a 2:1 safety margin. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. If your application involves high heat, you can specify the Viton H seal option to raise the operating temperature range from -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X140 Is Used
Heavy Stamping Press
Drives a heavy stamping die requiring 3927 N of push force at 0.5 MPa to form thick sheet metal components securely.
Pallet Dispenser
Pushes empty pallets into a conveyor line, utilizing the compact profile length to fit within dense warehouse logistics machinery.
Injection Mold Ejector
Acts as a heavy-duty ejection mechanism for large molded plastic parts, safely moving loads up to 200 kg vertically.
Is the Airtac SAU Standard Air Cylinder SAU100X140 the Right Cylinder?
When sizing this 100 mm bore unit, compare it against adjacent bores: a 63 mm cylinder provides 1559 N push at 0.5 MPa, while there is no larger standard SAU bore, making this the maximum force option in the series. This model shares mounting dimensions with AirTAC SC-series accessories, so you can use standard LB foot mounts, FA/FB flanges, or CA/CB clevis brackets. A rod knuckle (I, Y, F, or U) can also be fitted for articulating loads.
Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it does not function as a brake. If air pressure is lost or the valve is centered, the piston will drift. For applications requiring strict position holding, you must integrate an external rod lock or a pilot-operated check valve into your 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 SAU100X140 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force is 5497 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It features a 1/2" port, an M20x1.5 rod thread, and operates at speeds between 30-800 mm/s.
It is not an ISO 15552 cylinder, but it shares mounting accessory compatibility with the AirTAC SC series (LB, FA, FB, CA, CB). Because this specific SKU does not include the -S magnet, it cannot support CMSG, DMSG, or EMSG magnetic sensors.
