Airtac SAU Standard Air Cylinder SAU100X45
The AirTAC Airtac SAU Standard Air Cylinder SAU100X45 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 45mm 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 SAU100X45
The AirTAC SAU100X45 is a double-acting profile-type cylinder engineered for heavy-duty automation. It features an extruded aluminum barrel with a 1/2 inch port and a 25 mm piston rod, delivering 3927 N of push force at 0.5 MPa. Designed to be shorter than an ISO 15552 cylinder of the same bore, it saves valuable machine space while sharing AirTAC SC-series mounting accessories.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction at 0.5 MPa. This translates to lifting about 200 kg vertically with a 2:1 safety margin. The unit uses adjustable air cushions at both ends to decelerate the piston smoothly. Note that this specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU100X45 Is Used
Stamping Press Feed
Drives heavy material grippers in an automated metal stamping line, utilizing the 3927 N push force to securely clamp thick steel sheets before the press cycles.
Pallet Dispenser
Pushes empty pallets into a high-speed packaging conveyor, taking advantage of the compact profile length to fit within tight conveyor frame clearances.
Injection Mold Ejector
Acts as a heavy-duty knockout mechanism for large plastic injection molds, using its 200 kg vertical lift capacity to free dense molded parts from the cavity.
Is the Airtac SAU Standard Air Cylinder SAU100X45 the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against neighboring bores: the 80 mm option yields 2513 N push at 0.5 MPa, while the 100 mm provides 3927 N. If you need even more power, a larger custom solution may be required as 100 mm is the largest standard SAU bore. Because this stroke is only 45 mm, side-load risks are minimal, but always ensure rigid mounting using SC-series LB foot or FA flange brackets.
Remember that a standard cylinder drifts when air is lost or a valve is centered; the air cushion only decelerates the piston near stroke end and does not act as a brake. For vertical or suspended loads that must be held in place during a pressure drop, install an external rod lock or a pilot-operated check valve. Since this model lacks the -S suffix, position sensing is not supported out of the box.
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 SAU100X45 FAQ
This 100 mm bore model features a 1/2 inch port and a 25 mm rod. It delivers 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 that only shares mounting accessories with the AirTAC SC series (like LB, FA, and CA brackets). Additionally, this specific SKU does not have the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches.
