Airtac SAU Standard Air Cylinder SAU100X850S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X850S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 850mm 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 SAU100X850S
The AirTAC SAU100X850S is a double-acting profile-type cylinder engineered for heavy-duty automation. Featuring an extruded aluminum barrel, it provides a 3927 N push force at 0.5 MPa and a 1/2 inch port. Because it uses a profile barrel rather than a standard design, it is physically shorter than an ISO 15552 cylinder of the same 100 mm bore, saving valuable machine space. The integrated -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches along the built-in sensor groove.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In a vertical lift scenario with a 2:1 safety margin, this actuator lifts about 200 kg. The 850 mm stroke extends a 25 mm rod, and the adjustable air cushion at both ends ensures smooth deceleration. If your environment exceeds the standard -20 to +70 C range, a Viton H seal option extends operation to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X850S Is Used
Heavy Press Ejection
Provides the robust 3927 N push force needed to eject dense stamped metal parts from a hydraulic press bed.
Pallet Dispenser
Uses the long 850 mm stroke to push empty pallets horizontally into a packaging line with reliable force.
Logistics Divert Gate
Actuates a heavy diverting gate on a parcel sorting conveyor, utilizing the 1/2 inch port for rapid cycling.
Is the Airtac SAU Standard Air Cylinder SAU100X850S the Right Cylinder?
When sizing this 100 mm bore unit, compare it against neighboring bores: a 63 mm cylinder offers 1559 N push at 0.5 MPa, while an 80 mm provides 2513 N. This SAU100X850S delivers 3927 N, making it the top choice when those smaller options lack thrust. It shares mounting dimensions with AirTAC SC-series accessories, so you can use LB foot, FA/FB flange, or CA/CB clevis brackets. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing.
Because the 850 mm stroke is relatively long, prevent rod bending by guiding the load externally and minimizing side-load forces. Remember that a standard cylinder does not hold position if air pressure drops or the valve is centered; the piston will drift. The adjustable air cushion only decelerates the piston near the end of travel and never acts as a locking brake. For suspended loads, 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 SAU100X850S FAQ
This 100 mm bore cylinder 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. The theoretical maximum force is 801 kgf at 1.0 MPa.
Yes, it is a compact profile-type cylinder that is shorter than an ISO 15552 cylinder of the same bore. It is not ISO 15552 interchangeable, but it shares mounting accessories with the AirTAC SC series. The -S suffix means it includes a magnet for CMSG, DMSG, or EMSG sensors.
