Airtac SAU Standard Air Cylinder SAU100X375S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X375S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 375mm 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 SAU100X375S
The AirTAC SAU100X375S is a double-acting profile-type cylinder engineered for heavy-duty automation. Built with an extruded aluminum barrel, it provides a substantial 3927 N push and 3681 N pull at 0.5 MPa, utilizing a 1/2 inch port and an M20x1.5 rod thread. Its extruded profile design is notably shorter than an ISO 15552 cylinder of the same bore, offering a distinct space-saving advantage in tight machine layouts.
Because this SKU includes the -S magnet, it readily accepts CMSG, DMSG, or EMSG switches in the integrated sensor groove for precise position detection. For practical sizing, plan for a safe working load of roughly 2356 N—about 60% of the 0.5 MPa push rating—to account for seal friction and smooth travel. This translates to lifting about 200 kg vertically with a 2:1 safety margin, while the adjustable 29 mm air cushions at both ends decelerate the piston smoothly near stroke end.

Where the Airtac SAU Standard Air Cylinder SAU100X375S Is Used
Heavy Stamp Press Feed
Drives robust metal blanks into a stamping press, utilizing the 3927 N push force at 0.5 MPa to overcome die resistance and feed heavy gauge steel.
Palletized Goods Lift
Raises loaded pallets vertically, safely lifting approximately 200 kg thanks to the 2:1 safety margin derived from the 0.5 MPa thrust rating.
Automated Waste Compaction
Compresses industrial waste materials in a 375 mm stroke cycle, relying on the 29 mm adjustable air cushions to absorb kinetic energy at stroke end.
Is the Airtac SAU Standard Air Cylinder SAU100X375S the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against adjacent bores: a 63 mm bore yields 1559 N push at 0.5 MPa, whereas an 80 mm bore provides 2513 N. If 3927 N is insufficient, you would step up to a larger custom solution. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the air cushion only decelerates the piston and does not function as a locking brake. For suspended or vertical loads, install an external rod lock or a pilot-operated check valve.
With a 375 mm stroke, the 25 mm rod is susceptible to bending under lateral stress, so external guide rails are strongly recommended to prevent side-loading damage. This model shares its mounting footprint with AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises. Furthermore, the included -S magnet enables solid-state or reed sensor tracking along the entire 375 mm travel path.
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 SAU100X375S 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, and the theoretical maximum force is 801 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder, though it shares mounting dimensions with the AirTAC SC series (LB, FA, FB, CA, CB). Because this model has the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly into the barrel profile groove.
