Airtac SAU Standard Air Cylinder SAU100X145S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X145S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 145mm 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 SAU100X145S
The AirTAC SAU100X145S is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a substantial push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Designed with an extruded aluminum barrel, it provides a shorter overall length than a standard ISO 15552 cylinder of the same bore, yielding valuable space savings in dense machinery layouts. This unit operates on a 1/2" port and features a robust Ø25 mm piston rod with an M20x1.5 thread.
Because real-world friction and smooth travel reduce pure theoretical output, plan for a safe working load of roughly 2356 N (about 60% of the 0.5 MPa push force). For vertical lifting tasks, this translates to hoisting approximately 200 kg with a safe 2:1 margin. The included -S piston magnet enables direct mounting of CMSG, DMSG, or EMSG sensors in the integrated profile groove. For high-temperature environments up to 150 C, you can specify the Viton H seal option instead of the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU100X145S Is Used
Heavy Press Ejection
Provides the robust 3927 N push force required to eject dense metal stampings from a hydraulic press bed, utilizing the compact profile to fit within tight press columns.
Pallet Dispenser Pusher
Handles the heavy lateral force needed to separate empty wooden pallets in an automated palletizing line, lifting or pushing loads up to 200 kg vertically with a safe margin.
Injection Mold Platen Shift
Shifts heavy injection molding platens into position, leveraging the 1/2" port and Ø25 mm rod to maintain rigidity and high flow for rapid 30-800 mm/s cycling.
Is the Airtac SAU Standard Air Cylinder SAU100X145S the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against adjacent bores to match your exact load requirements. Stepping down to the 80 mm bore yields 2513 N of push force at 0.5 MPa, while this 100 mm unit provides 3927 N. If you need even more power, note that 100 mm is the largest standard SAU bore available. This 145 mm stroke falls well under the 1500 mm maximum, so standard rod bending is not a primary concern here. Remember that a standard double-acting cylinder like this will drift if air pressure is lost or the valve is centered; the adjustable 29 mm air cushions only decelerate the piston near the end caps and do not function as a braking lock. For suspended or vertical loads that must remain stationary during air loss, integrate an external rod lock or a pilot-operated check valve. Mounting is straightforward using AirTAC SC-series accessories, including LB foot mounts, 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 SAU100X145S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force is 5497 N, and at 0.9 MPa it reaches 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It features a 100 mm bore, 145 mm stroke, Ø25 mm rod, 1/2" port, M20x1.5 rod thread, and a speed range of 30-800 mm/s.
No, the SAU is a profile-type cylinder and is not dimensionally interchangeable with ISO 15552 standards. You must use AirTAC SC-series mounting accessories like LB foot, FA/FB flange, or CA/CB clevis. Because this SAU100X145S model includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly into the extruded barrel groove.
