Airtac SAU Standard Air Cylinder SAU100X700S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X700S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 700mm 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 SAU100X700S
The AirTAC SAU100X700S is a double-acting profile-type cylinder featuring a 100mm bore and 700mm stroke. Its extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore, providing a space advantage in large-scale machinery. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. The 1/2" port and M20x1.5 rod thread handle high airflow for rapid cycling across the 30-800 mm/s speed range.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In vertical lift setups, this translates to lifting roughly 200 kg with a 2:1 safety margin. The included -S magnet enables CMSG, DMSG, or EMSG sensors to track position directly via the profile groove. For high-temperature environments up to 150 C, specify the Viton H seal option over the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU100X700S Is Used
Automotive Body Welding
Drives large spot-welding guns on vehicle frames, utilizing the 3927 N push force to clamp heavy steel panels securely during the robotic welding process.
Pallet Dispenser Pusher
Actuates a 700mm stroke to index empty pallets into a high-speed packaging line, benefiting from the compact profile length to fit within tight conveyor footprints.
Injection Mold Ejection
Ejects dense plastic automotive bumpers from large injection molding machines, relying on the 1/2" port for rapid exhaust and fast retraction cycles.
Is the Airtac SAU Standard Air Cylinder SAU100X700S the Right Cylinder?
When sizing this 100mm bore actuator, consider the neighboring bores to match your exact force requirements. Stepping down to the 80mm bore yields 2513 N of push force at 0.5 MPa, while this 100mm unit provides 3927 N. If you need maximum thrust, the 100mm bore is the largest available in the SAU series, offering a theoretical maximum of 801 kgf at 1.0 MPa. Mounting is facilitated using AirTAC SC-series accessories, such as LB foot brackets or FA flanges.
Because this unit features a 700mm stroke, external guide rails are strongly recommended to prevent rod bending and absorb side loads. Remember that the adjustable 29mm air cushions only decelerate the piston near the end of travel; they do not function as a brake. If the machine loses air pressure, the piston will drift, so an external rod lock or pilot-operated check valve is necessary to hold a suspended load safely.
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 SAU100X700S FAQ
This 100mm bore cylinder features 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, with a theoretical maximum of 801 kgf at 1.0 MPa.
No, it is not dimensionally interchangeable with ISO 15552 cylinders, though it shares mounting accessories with the AirTAC SC series (like LB, FA, and CA brackets). Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly into the extruded profile barrel groove.
