Airtac SAU Standard Air Cylinder SAU100X35
The AirTAC Airtac SAU Standard Air Cylinder SAU100X35 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 35mm 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 SAU100X35
The AirTAC SAU100X35 is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a substantial push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Its extruded aluminum barrel design makes it shorter and more compact than a standard ISO 15552 cylinder of the same bore, providing a significant space advantage in tight machine layouts. The unit features a 1/2 inch air port, an M20x1.5 rod thread, and a 25 mm piston rod.
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 a vertical lifting scenario, this translates to lifting roughly 200 kg with a 2:1 safety margin. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing. If your application involves high heat, you can opt for Viton H seals to raise the operating temperature range from the standard -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X35 Is Used
Injection Mold Clamping
Provides the heavy 3927 N clamping thrust needed to secure large injection mold halves, utilizing its compact profile to fit within dense press frameworks.
Pallet Stopper Gate
Acts as a high-force pneumatic stop gate on heavy-duty roller conveyors, halting loaded pallets weighing up to 200 kg in vertical lift equivalents.
Press Pin Insertion
Drives large-diameter dowel pins into heavy steel assemblies, where the 1/2 inch port ensures rapid volume flow for quick actuation cycles.
Is the Airtac SAU Standard Air Cylinder SAU100X35 the Right Cylinder?
When sizing this model, consider the adjacent bores in the range: the SAU80 offers 2513 N push at 0.5 MPa if your load is lighter, while there is no larger bore in the SAU series, making the 100 mm the maximum thrust option at 801 kgf theoretical max force at 1.0 MPa. Because this is a plain cylinder without a magnet, you cannot mount reed or solid-state sensors directly; if position feedback is required, select an SAU100X35-S instead. Mounting is highly versatile, sharing the exact same accessories as the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis brackets. With a short 35 mm stroke, side-load risks are minimal, but always ensure rigid rod-end coupling.
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 SAU100X35 FAQ
The SAU100X35 features a 1/2 inch air port and delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa, the push force is 5497 N, and the theoretical maximum force is 801 kgf at 1.0 MPa.
No, a plain double-acting cylinder drifts when air is exhausted or the valve is centered. The adjustable air cushion only decelerates the piston near the stroke end and does not act as a brake. To maintain a vertical load, you must use an external rod lock or a pilot-operated check valve.
