Airtac SAU Standard Air Cylinder SAU100X450S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X450S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 450mm 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 SAU100X450S
The AirTAC SAU100X450S is a double-acting profile-type cylinder with a 100mm bore and 450mm stroke. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, providing a space win in tight machinery. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, operating on a 1/2" port with a 25mm rod. The unit includes adjustable air cushions of 29mm at both ends to decelerate the piston smoothly.
For real-world sizing, plan for a safe working load of about 2356 N (60% of the 0.5 MPa push figure) to account for seal friction and smooth travel. This equates to lifting about 200 kg vertically with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet, enabling CMSG, DMSG, or EMSG reed and electronic switches to seat directly in the profile groove. For high-temperature environments up to 150 C, specify the Viton H seal option instead of the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU100X450S Is Used
Heavy Press Ejection
Ejects formed metal parts from a 200-ton hydraulic press, utilizing the 3927 N push force to break the part free from the die.
Pallet Dispenser
Pushes empty pallets into a packaging line feeder, where the 450mm stroke provides the exact reach needed to load the next stack.
Vertical Lift Gate
Actuates a heavy material lift gate, safely raising a 150kg fixture using the 2:1 vertical lift margin without overloading the seals.
Is the Airtac SAU Standard Air Cylinder SAU100X450S the Right Cylinder?
When sizing this actuator, compare it to adjacent bores: the 80mm bore yields 2513 N push at 0.5 MPa, while this 100mm bore provides 3927 N. If your application exceeds 3927 N, you are at the top of the standard SAU range and should explore other series. Because this is a 450mm stroke, external guides are strongly recommended to prevent rod bending and premature seal wear from side loads. Mounting hardware matches the AirTAC SC series, allowing you to use LB foot brackets, FA/FB flanges, or CA/CB clevises. Remember that a standard cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The air cushion only slows travel at the end of the stroke, so add an external rod lock or pilot-operated check valve for suspended loads.
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 SAU100X450S FAQ
This 100mm bore cylinder features a 1/2" port and a 25mm piston rod. It 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, and the theoretical maximum force is 801 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder, but it shares mounting accessories with the AirTAC SC series (LB, FA, FB, CA, CB). Because this SKU includes the -S magnet, you can install CMSG, DMSG, or EMSG switches directly into the extruded profile barrel groove.
