Airtac SAU Standard Air Cylinder SAU100X185
The AirTAC Airtac SAU Standard Air Cylinder SAU100X185 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 SAU100X185
The AirTAC SAU100X185 is a double-acting profile-type cylinder built around an extruded aluminium barrel, engineered to be shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. This specific configuration features a non-standard 185 mm made-to-order stroke. It delivers substantial power, generating a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. The 1/2" air port and M20x1.5 rod-end thread ensure high flow and robust mechanical attachment for heavy-duty cycles. Operating speeds span 30-800 mm/s, regulated by a 29 mm adjustable air cushion at both ends to decelerate the payload smoothly.
For practical sizing, plan for a safe working load of roughly 2356 N—about 60 percent of the 0.5 MPa push rating—to account for seal friction and smooth travel. Alternatively, you can expect it to lift about 200 kg vertically with a 2:1 safety margin. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. If your thermal environment is extreme, you can specify the Viton H high-temperature seal option to push the operating range from -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X185 Is Used
Heavy Press Ejection
Provides the robust 3927 N push force required to eject dense stamped metal components from a hydraulic press bed in automotive fabrication lines.
Pallet Dispenser Gate
Actuates heavy-duty mechanical gates in automated pallet dispensers, where the compact profile saves valuable floor space in tight conveyor zones.
Injection Mold Separation
Drives the separation of large injection molding tooling halves, utilising its 185 mm stroke and high pull force to safely break vacuum suction on finished parts.
Is the Airtac SAU Standard Air Cylinder SAU100X185 the Right Cylinder?
When sizing this actuator, compare it against its neighbours: the 80 mm bore yields 2513 N of push at 0.5 MPa, whereas this 100 mm unit provides 3927 N. If you need even more power, you have reached the top of the SAU range. Keep in mind that a standard double-acting cylinder like this will drift if air pressure is lost or the valve is centred; the integrated air cushion only decelerates the piston near the stroke ends and does not function as a braking lock. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Mounting hardware is fully compatible with AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises.
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 SAU100X185 FAQ
This 100 mm bore cylinder provides 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, reaching 7068 N at 0.9 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. It features a 1/2" port, an M20x1.5 rod thread, and operates at speeds of 30-800 mm/s.
It is not an ISO 15552 cylinder, so you must use AirTAC SC-series mounting accessories like LB, FA, FB, CA, or CB brackets. Additionally, because this specific SKU lacks the -S magnet suffix, it cannot support CMSG, DMSG, or EMSG magnetic sensors.
