Airtac SAU Standard Air Cylinder SAU100X240S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X240S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 240mm 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 SAU100X240S
The AirTAC SAU100X240S is a double-acting profile-type cylinder featuring a 100 mm bore and a 240 mm stroke. It utilizes an extruded aluminum barrel with a built-in sensor groove, making it significantly shorter and more compact than a standard ISO 15552 cylinder of the same bore. In this force class, it delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, operating with a 1/2 inch air port and a 25 mm carbon steel rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for roughly 60% of the 0.5 MPa push rating to offset seal friction and ensure smooth travel. Alternatively, you can use it to lift a 200 kg mass vertically with a 2:1 safety margin. The included -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position detection, and a Viton H high-temperature seal option extends the operating range from -20 to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X240S Is Used
Heavy Press Ejection
Ejects thick metal stampings from a 200-ton hydraulic press, utilizing the 3927 N push force to break the part free from the die.
Pallet Dispenser Gate
Actuates a heavy-duty pneumatic gate in an automated palletizing cell, lifting and indexing empty wooden pallets up to 200 kg.
Injection Mold Clamping
Provides auxiliary side-core pulling on a large plastic injection molding machine, fitting into tight mold bases due to the compact profile barrel.
Is the Airtac SAU Standard Air Cylinder SAU100X240S the Right Cylinder?
When sizing this 100 mm bore model, evaluate your neighbors: a 63 mm bore yields 1559 N of push force at 0.5 MPa, while stepping up is not required as this is the largest standard SAU option, delivering a maximum theoretical 801 kgf at 1.0 MPa. Because this unit features the -S magnet, you can easily integrate CMSG or DMSG sensors into the extruded profile groove. Mounting hardware is fully compatible with AirTAC SC-series accessories, including LB foot mounts, FA flanges, and CA clevises.
Keep in mind that a standard double-acting cylinder will drift if air pressure drops or the valve is centered; the adjustable 29 mm air cushions only decelerate the piston near the end of stroke and do not function as a locking brake. If your application requires absolute load holding on air loss, you must add an external rod lock mechanism or a pilot-operated check valve to the 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 SAU100X240S FAQ
This 100 mm bore model features a 1/2 inch air port. The force output is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
No, it is not dimensionally interchangeable with ISO 15552 cylinders, but it shares mounting accessories with the AirTAC SC series (LB, FA, CA). The -S suffix indicates a built-in magnet, allowing the use of CMSG, DMSG, or EMSG switches in the profile groove.
