Airtac SAU Standard Air Cylinder SAU100X185S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X185S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 185mm 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 SAU100X185S
The AirTAC SAU100X185S is a double-acting profile-type cylinder engineered to be shorter than an ISO 15552 unit of the same bore, saving valuable machine real estate. It delivers a robust 3927 N of push force at 0.5 MPa, operating via a 1/2 inch port and a 25 mm rod with an M20x1.5 thread. The integrated -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches into the extruded barrel groove for precise position detection.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In vertical lifting tasks, this translates to safely hoisting roughly 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 SAU100X185S Is Used
Injection Mold Clamping
Provides high clamping thrust for securing heavy injection mold halves, utilizing the compact profile length to fit within tight press frameworks.
Pallet Stopper Gate
Acts as a heavy-duty stopper arm on conveyor lines, easily halting fully loaded pallets while the integrated magnet tracks gate position.
Vertical Lift Trolley
Drives vertical lifting platforms for heavy trolleys, capitalizing on the 200 kg safe vertical lift capacity to raise industrial components reliably.
Is the Airtac SAU Standard Air Cylinder SAU100X185S the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against neighboring options. Dropping down to an 80 mm bore yields 2513 N of push at 0.5 MPa, whereas this 100 mm unit provides 3927 N, making it the right choice when the smaller variant lacks thrust. If you need even more power, note that 100 mm is the largest standard SAU bore available. Because this 185 mm stroke is under 300 mm, rod bending is minimal, but always ensure rigid SC-series mounting using LB foot or FA flange brackets.
Remember that the adjustable air cushions at both ends only decelerate the piston near the stroke limits; they do not function as a braking mechanism. If your application must hold a load vertically during a pressure drop or valve centering, you must add an external rod lock or a pilot-operated check valve, as the piston will drift otherwise.
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 SAU100X185S FAQ
This 100 mm bore model features a 1/2 inch port and generates 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.
You cannot use ISO 15552 brackets, as the SAU is a distinct compact profile design. It shares mounting accessories only with the AirTAC SC series (like LB foot and FA flange). However, the -S suffix means it has a built-in magnet, allowing you to use CMSG, DMSG, or EMSG sensors in the barrel groove.
