Airtac SAU Standard Air Cylinder SAU100X140S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X140S 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 SAU100X140S
The AirTAC SAU100X140S is a double-acting profile-type cylinder engineered for heavy-duty tasks. It provides a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Its extruded aluminum barrel design is noticeably shorter than an ISO 15552 cylinder of the same bore, offering a significant space advantage in tight machinery layouts. The unit features a 1/2 inch air port, an M20x1.5 rod thread, and a 25 mm piston rod.
Because this SKU includes the -S magnet, it readily supports CMSG, DMSG, or EMSG reed and electronic switches directly in the profile groove. For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. Alternatively, you can expect it to lift roughly 200 kg vertically with a 2:1 safety margin. If your environment exceeds standard thermal limits, specifying the Viton H seal option extends the operating range up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X140S Is Used
Heavy Stamping Press
Drives a 150 kg upper die set in an automotive stamping line, utilizing the 3927 N push force to cleanly shear thick steel blanks.
Pallet Dispenser
Pushes empty wooden pallets into a packaging conveyor, where the compact profile length prevents interference with adjacent robotic pickers.
Vertical Lift Gate
Actuates a 180 kg material lift gate, safely staying within the 200 kg vertical lift capacity while benefiting from the built-in magnet for position feedback.
Is the Airtac SAU Standard Air Cylinder SAU100X140S the Right Cylinder?
When sizing this actuator, compare it against adjacent bores to match your exact load requirements. Stepping down to the 80 mm bore reduces the 0.5 MPa push force to 2513 N, while stepping up is not available as 100 mm is the maximum SAU capacity. The 140 mm stroke keeps the overall length highly manageable and well below side-load risk thresholds. To mount this unit, utilize standard AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises.
Remember that a standard double-acting cylinder will drift if air pressure drops or the valve is centered. The adjustable 29 mm air cushions at both ends only decelerate the piston near the stroke ends; they do not function as a braking mechanism. For applications requiring absolute load holding on air loss, 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 SAU100X140S FAQ
This 100 mm bore model uses a 1/2 inch port. 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.
No, it is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, accepting LB, FA, FB, CA, and CB brackets. Because this model has the -S magnet, you can install CMSG, DMSG, or EMSG sensors directly into the barrel groove.
