Airtac SAU Standard Air Cylinder SAU100X40S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X40S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 40mm 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 SAU100X40S
The AirTAC SAU100X40S is a double-acting profile-type cylinder built for high-force tasks in tight machine envelopes. Its extruded aluminum barrel makes it shorter than a same-bore ISO 15552 unit, yielding 3927 N of push force at 0.5 MPa through a 1/2 inch port. Plan for a safe working load of roughly 2356 N to account for seal friction, which lets you reliably lift about 200 kg vertically with a 2:1 safety margin.
This unit includes a piston magnet (-S) for direct mounting of CMSG, DMSG, or EMSG sensors along the profile groove. The standard TPU seals handle -20 to +70 C, but a Viton H option extends heat resistance up to 150 C. It shares its mounting footprint with AirTAC SC-series accessories, utilizing a 25 mm hard-chrome rod and M20x1.5 thread.

Where the Airtac SAU Standard Air Cylinder SAU100X40S Is Used
Heavy Stamp Pressing
Drives short-stroke stamping dies with 3927 N of push force at 0.5 MPa, fitting into compact press frames.
Pallet Clamp Actuation
Secures heavy pallets in packaging lines, lifting roughly 200 kg loads vertically with a safe 2:1 margin.
Injection Mold Ejection
Ejects dense plastic parts from molds using a 25 mm hard-chrome rod, surviving ambient heat with optional Viton H seals.
Is the Airtac SAU Standard Air Cylinder SAU100X40S the Right Cylinder?
When sizing this 100 mm bore, dropping down to an 80 mm bore reduces the 0.5 MPa push force to 2513 N, while no larger standard SAU bore exists. The integrated -S magnet enables CMSG/DMSG/EMSG switches for position detection. Note that standard air cushions only decelerate the piston near stroke ends; because the piston drifts on air loss, add an external rod lock or pilot-operated check valve for suspended loads.
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 SAU100X40S FAQ
This 100 mm bore cylinder features a 1/2 inch port and delivers 3927 N push / 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder. It is a compact profile cylinder that uses AirTAC SC-series mounting accessories like LB foot, FA flange, or CA clevis. The -S magnet allows CMSG/DMSG/EMSG sensors.
