Airtac SAU Standard Air Cylinder SAU100X275S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X275S 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 SAU100X275S
The AirTAC SAU100X275S 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, scaling up to a theoretical maximum of 801 kgf at 1.0 MPa. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, providing a distinct space advantage in large machinery. The unit features a 1/2" air port and a 25 mm piston rod with an M20x1.5 thread.
Because the -S suffix denotes a built-in piston magnet, this model is fully compatible with CMSG, DMSG, and EMSG reed or electronic switches that mount directly into the profile groove. For practical sizing, plan for a safe working load of about 2356 N (roughly 60% of the 0.5 MPa push rating) to account for seal friction and smooth travel. Alternatively, it can safely lift a 200 kg vertical mass when applying a 2:1 safety margin.

Where the Airtac SAU Standard Air Cylinder SAU100X275S Is Used
Injection Mold Clamping
Provides the heavy 3927 N push force required to secure large injection molding tooling plates during low-pressure closing cycles.
Pallet Diverting
Handles robust 200 kg vertical or lateral loads to redirect heavy pallets on automated packaging and distribution conveyor lines.
Press Ejection
Generates reliable ejection thrust to push dense finished parts out of hydraulic presses operating at up to 0.7 MPa.
Is the Airtac SAU Standard Air Cylinder SAU100X275S the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against adjacent bores: the 80 mm option yields 2513 N of push force at 0.5 MPa, while there is no larger standard SAU bore, making this the top-tier choice for maximum thrust. The 275 mm stroke is well below the 1500 mm standard maximum, keeping the assembly rigid without requiring auxiliary guides. Mounting is straightforward using AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises. Remember that the adjustable air cushion only decelerates the piston near the end of travel; it does not function as a brake. If your application must hold a load vertically during a loss of air pressure, 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 SAU100X275S FAQ
This 100 mm bore cylinder uses a 1/2" air port. It generates a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, a push force of 5497 N at 0.7 MPa, and reaches a theoretical maximum of 801 kgf at 1.0 MPa.
You cannot use ISO 15552 accessories, as the SAU is a compact profile cylinder that is shorter than ISO standards. It shares mounting dimensions only with the AirTAC SC series (LB, FA, FB, CA, CB). The -S magnet in this model allows CMSG, DMSG, and EMSG sensors to be fitted directly into the barrel groove.
