Airtac SAU Standard Air Cylinder SAU100X85
The AirTAC SAU Standard Air Cylinder SAU100X85 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 85mm 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 SAU100X85
The AirTAC SAU100X85 is a double-acting profile-type cylinder with an 85 mm stroke. Built with an extruded aluminum barrel, it is purposefully shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, saving valuable machine space. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, utilizing a 1/2 inch port and an M20x1.5 rod thread. This specific 85 mm stroke is a non-standard, made-to-order configuration.
The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this to 0-150 C. Note that because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU100X85 Is Used
Press Fit Assembly
Drives heavy bushings into automotive transmission housings, utilizing the 3927 N push force at 0.5 MPa to seat components reliably.
Pallet Dispenser
Separates empty wooden pallets from a magazine stack, where the compact profile length prevents interference with adjacent conveyor structures.
Injection Mold Ejector
Pushes large molded plastic bins out of a press, using the 85 mm stroke and robust 25 mm rod to overcome mold release friction.
Is the Airtac SAU Standard Air Cylinder SAU100X85 the Right Cylinder?
When sizing this actuator, compare it against adjacent bores: a 63 mm bore yields 1559 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. If 3927 N is insufficient, you would step up to a larger custom solution, as 100 mm is the largest standard SAU bore. This model shares its mounting footprint with AirTAC SC-series accessories, including LB foot mounts, FA/FB flanges, and CA/CB clevises. Since the stroke is under 300 mm, severe rod bending is less critical, but always guide the load to prevent side forces.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The adjustable 29 mm air cushions at both ends only decelerate the piston near the end of travel; they do not function as a locking brake. To suspend a load safely during an emergency stop or pressure drop, 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 SAU100X85 FAQ
The 100 mm bore 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, and the theoretical maximum is 801 kgf at 1.0 MPa. It uses a 1/2 inch air port, a 25 mm rod, and an M20x1.5 rod-end thread.
No, it is not an ISO 15552 cylinder and does not share that footprint. The SAU100X85 is a compact profile cylinder that uses AirTAC SC-series mounting accessories, such as LB foot mounts, FA/FB flanges, and CA/CB clevises. Additionally, this specific SKU lacks a magnet, so it cannot support magnetic position sensors.
