Airtac SAU Standard Air Cylinder SAU100X325S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X325S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 325mm 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 SAU100X325S
The AirTAC SAU100X325S is a double-acting profile-type cylinder engineered to deliver massive thrust in a footprint notably shorter than a same-bore ISO 15552 unit. At its core, this 100 mm bore actuator generates 3927 N of push force at 0.5 MPa, utilizing a 25 mm carbon steel rod and a 1/2" air port. Because the extruded aluminum barrel integrates a sensor groove, the included -S piston magnet works seamlessly with CMSG, DMSG, or EMSG switches for precise end-of-stroke detection.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. In vertical lift applications, this translates to hoisting about 200 kg with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this range up to 150 C for high-heat environments.

Where the Airtac SAU Standard Air Cylinder SAU100X325S Is Used
Heavy Stamping Press
Drives a 200 kg upper die set in an automotive stamping line, utilizing the 3927 N push force to form steel panels reliably.
Pallet Dispenser
Pushes empty pallets into a high-speed packaging conveyor, where the 325 mm stroke provides the exact reach needed to load the queue.
Vertical Lift Gate
Actuates a heavy materials handling gate, lifting approximately 200 kg vertically while the -S magnet tracks the gate position.
Is the Airtac SAU Standard Air Cylinder SAU100X325S the Right Cylinder?
When sizing this actuator, evaluate the neighboring bores: a 63 mm unit yields 1559 N at 0.5 MPa, whereas an 80 mm variant provides 2513 N, making the 100 mm bore the definitive choice when those smaller options lack sufficient power. Because this SKU features a 325 mm stroke, external guide rails are strongly recommended to prevent rod bending and absorb side loads during extended traversal. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it will not hold a load if air pressure drops. To prevent drifting, install an external rod lock or a pilot-operated check valve. Mounting is straightforward using AirTAC SC-series accessories like LB foot brackets or FA flanges.
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 SAU100X325S FAQ
This 100 mm bore cylinder features a 25 mm rod, M20x1.5 rod thread, and a 1/2" port. It delivers 3927 N push and 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. It includes a 29 mm adjustable air cushion at both ends and operates at speeds between 30-800 mm/s.
No, it is not dimensionally interchangeable with ISO 15552 standards, though it is purposefully built to be more compact. You must use AirTAC SC-series mounting accessories like CA clevis or FB flanges. Because this is the -S variant, it contains a piston magnet and fully supports CMSG, DMSG, and EMSG sensor switches.
