Airtac SAU Standard Air Cylinder SAU100X250S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X250S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 250mm 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 SAU100X250S
The AirTAC SAU100X250S is a double-acting profile-type cylinder engineered for heavy-duty tasks. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Its extruded aluminum barrel design is more compact than a standard ISO 15552 cylinder of the same bore, offering a distinct space-saving advantage in tight machine layouts. The unit features a 1/2" port and a 25 mm rod with an M20x1.5 thread.
Because this SKU includes the -S magnet, it readily supports CMSG, DMSG, or EMSG electronic switches in the profile groove. For practical sizing, plan for a safe working load of roughly 2356 N (about 60% of the 0.5 MPa push figure) to account for seal friction and smooth travel. Alternatively, it can vertically lift about 200 kg with a 2:1 safety margin, letting you match real part weights directly.

Where the Airtac SAU Standard Air Cylinder SAU100X250S Is Used
Heavy Stamping Press
Drives a 150 kg upper die set in an automotive stamping line, utilizing the 200 kg vertical lift capacity to ensure smooth, powerful descent.
Pallet Dispenser
Pushes empty wooden pallets into a packaging conveyor, where the 2356 N safe working load easily overcomes stack friction without stalling.
Injection Mold Ejector
Actuates a heavy mold ejection plate in a plastics plant, relying on the 250 mm stroke and compact profile to fit within narrow press frames.
Is the Airtac SAU Standard Air Cylinder SAU100X250S the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa, while this model provides 3927 N. If your application requires even more power, note that 100 mm is the largest standard SAU bore available. To secure loads against gravity during air loss or valve centering, add an external rod lock or pilot-operated check valve, as the standard air cushion only decelerates the piston near stroke end and will not hold a load. Mounting is straightforward using AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets.
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 SAU100X250S FAQ
This 100 mm bore cylinder features a 1/2" port and 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.
It is not an ISO 15552 cylinder, but it shares mounting accessories with the AirTAC SC series, such as LB foot, FA/FB flange, and CA/CB clevis. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors in the profile groove.
