Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 900mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08B
The SAUF100X900S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the 100mm bore and 900mm stroke directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a piston magnet for CMSG/DMSG/EMSG switches.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers 3927 N push at 0.5 MPa. A practical safe working load is roughly 2356 N (about 60% of the 0.5 MPa figure), offering a 200 kg vertical lift capacity with a 2:1 margin. The 1/4" port valve flows 25 mm2 (Cv 1.4) at up to 4 cycles/s, while the cylinder bore uses a 1/2" port with a 29 mm cushion.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08B Is Used
Pallet Divertor
Uses one coil signal per actuator to push heavy pallets off a high-speed line without running long tubing back to a central manifold.
Vertical Lift Gate
Lifts materials using the 100mm bore force, relying on the integrated DC24V valve for compact decentralized control at the station.
Long-Stroke Press
Drives a 900mm forming tool where the built-in 4M310-08 valve saves installation time and eliminates a remote valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08B the Right Choice?
Size by checking both neighboring bores: the 80mm bore yields 2513 N push at 0.5 MPa, while the 100mm bore provides 3927 N. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread meet your control spec. The rod retracts when energized by default, but you can reposition the valve to extend on signal. For this 900mm stroke, add external guides to prevent rod bending and side-load wear. The built-in valve routes air; it is not a lock, so add an external rod lock or pilot-operated check valve for held loads.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08B FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs on DC24V. Size the assembled unit strictly within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod on signal, but you can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This allows you to adapt the actuator to your machine logic without extra plumbing.
