Airtac SAU Standard Air Cylinder SAU100X275
The AirTAC Airtac SAU Standard Air Cylinder SAU100X275 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 275mm 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 SAU100X275
The AirTAC SAU100X275 is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, scaling up to 5497 N at 0.7 MPa. Its extruded aluminum barrel with a 1/2 inch port and M20x1.5 rod thread makes it significantly shorter than an ISO 15552 cylinder of the same bore, saving valuable machine footprint without sacrificing power.
For practical sizing, plan for a safe working load of about 2356 N at 0.5 MPa to account for seal friction and smooth travel. This translates to lifting roughly 200 kg vertically with a 2:1 safety margin. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensor switches. If your application involves high heat, you can specify the Viton H seal option to raise the operating range from -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X275 Is Used
Heavy Stamp Press Feed
Drives robust clamping arms in an automotive stamping line, utilizing the 3927 N push force to secure heavy steel blanks before the press cycles.
Pallet Dispenser Gate
Actuates a heavy-duty diverter gate in a high-throughput logistics hub, where the 275 mm stroke and 200 kg vertical lift capacity easily redirect loaded pallets.
Injection Mold Ejection
Provides reliable ejection force for thick-walled plastic components, leveraging the 1/2 inch port for rapid air exchange and fast cycling.
Is the Airtac SAU Standard Air Cylinder SAU100X275 the Right Cylinder?
When sizing this 100 mm bore actuator, compare it to neighboring bores: a 63 mm unit offers 1559 N push at 0.5 MPa, while the 100 mm provides 3927 N, making it the top choice for high-force demands within this series. Because this model has no -S suffix, magnetic position sensing is unavailable. If you need drop-in mounting hardware, the AirTAC SC series accessories (LB foot, FA/FB flange, CA/CB clevis) fit perfectly. Note that the adjustable air cushion at both ends only decelerates the piston near stroke end; it does not act as a brake. To prevent drift on air loss, install an external rod lock or 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 SAU100X275 FAQ
This 100 mm bore model features a 1/2 inch port and delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa the push force is 5497 N, reaching 7068 N at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
Yes, it shares mounting accessory compatibility with the AirTAC SC series, including LB, FA, FB, CA, and CB brackets. However, because this SKU lacks the -S magnet option, it cannot support CMSG, DMSG, or EMSG magnetic sensors.
