Airtac SAU Standard Air Cylinder SAU100X400S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X400S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 400mm 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 SAU100X400S
The AirTAC SAU100X400S is a double-acting profile-type cylinder engineered for heavy-duty tasks. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Built with an extruded aluminum barrel, its overall length is shorter than an ISO 15552 cylinder of the same bore, providing a space-saving advantage in large machinery. The unit features a 1/2" port and a 29 mm adjustable air cushion at both ends to absorb impact.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. This bore also lifts roughly 200 kg vertically when applying a 2:1 safety margin to the 0.5 MPa push figure. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly into the barrel groove for position detection. If your environment exceeds 70 C, specify the Viton H seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X400S Is Used
Heavy Stamping Press
Drives a 150 kg upper die set in an automotive stamping line, utilizing the 3927 N push force at 0.5 MPa to form steel brackets reliably.
Pallet Dispenser
Pushes empty pallets into a high-speed packaging conveyor, where the 400 mm stroke provides the necessary reach to load the stacking zone.
Injection Mold Ejector
Ejects dense plastic automotive interior panels from a large injection molding machine, using the adjustable 29 mm cushion to stop the 25 mm rod smoothly.
Is the Airtac SAU Standard Air Cylinder SAU100X400S the Right Cylinder?
When sizing this unit, compare it to adjacent bores: a 63 mm bore yields 1559 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. The 100 mm bore is necessary when your application demands the full 3927 N push at 0.5 MPa or the theoretical maximum of 801 kgf at 1.0 MPa. Mounting is straightforward using AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets. For this 400 mm stroke, external guides are strongly recommended to prevent rod bending and premature seal wear caused by side loads. Remember that a standard cylinder drifts when air is lost; the air cushion only decelerates the piston near the end of travel and does not function as a braking lock. To suspend a load safely during an air loss event, 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 SAU100X400S FAQ
This 100 mm bore model features a 1/2" 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 brackets; you must use AirTAC SC-series accessories like FA flange or LB foot mounts. However, because this model has the -S magnet, it fully supports CMSG, DMSG, and EMSG sensors in the profile barrel groove.
