Airtac SAU Standard Air Cylinder SAU100X950
The AirTAC Airtac SAU Standard Air Cylinder SAU100X950 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 950mm 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 SAU100X950
The AirTAC SAU100X950 is a double-acting profile-type standard cylinder featuring a 100 mm bore and a 950 mm stroke. Because it uses an extruded aluminum barrel rather than a conventional assembly, the overall length is noticeably shorter than an ISO 15552 cylinder of the same bore, which yields a significant space advantage in large-scale machinery. It delivers a robust 3927 N of push force and 3681 N of pull force at 0.5 MPa, operating on a 1/2" air port with a 29 mm adjustable air cushion at both ends.
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. In vertical lift applications, this translates to lifting about 200 kg safely with a 2:1 margin. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing. If your environment involves high heat up to 150 C, you can specify the Viton H seal option instead of the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU100X950 Is Used
Automated Press Ejection
Provides the heavy 3927 N push force required to eject formed metal parts from a hydraulic press bed, utilizing the compact profile to fit within tight machine columns.
Pallet Dispenser Mechanism
Drives a 950 mm stroke to lift and separate empty pallets from a magazine stack, where the long travel and high thrust handle rigid pallet weights effectively.
Heavy Log Sorting Gate
Actuates a large diverter gate on a timber processing line, relying on the 1/2" port and high flow capacity to shift heavy wood loads quickly and reliably.
Is the Airtac SAU Standard Air Cylinder SAU100X950 the Right Cylinder?
When sizing this actuator, consider the neighboring bores: stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while this 100 mm bore provides 3927 N. If you need even more power, there is no larger standard SAU bore, so you would look outside the series. Because this unit lacks the -S magnet, it cannot host reed or solid-state sensors; if detection is required, select an SAU100X950-S or use external mechanical switches. Mounting hardware like LB foot brackets, FA flanges, and CA clevises are fully compatible with the AirTAC SC series.
With a 950 mm stroke, the 25 mm piston rod is highly susceptible to side-load and bending forces. You must use external guide rails or linear bearings to support the load and prevent rod damage. Furthermore, this standard cylinder will drift if air pressure is lost or the control valve is centered; the end-of-stroke cushions only decelerate the piston and do not act as a locking brake. To suspend a load safely during an emergency stop, 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 SAU100X950 FAQ
This 100 mm bore cylinder uses a 1/2" air port and an M20x1.5 rod thread. 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.
It shares mounting dimensions only with the AirTAC SC series (LB, FA, CA accessories), not ISO 15552. Additionally, this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic sensors.
