Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 250mm 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 SAUF100X250-08A
The SAUF100X250-08A is an extruded aluminum profile double-acting cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 100mm bore uses a 1/2" port, a Ø25mm rod, M20x1.5 thread, and 29mm adjustable cushions. It is shorter than an ISO 15552 cylinder of the same bore.
Operating in the 0.15-0.8 MPa valve range, it pushes 3927 N and pulls 3681 N at 0.5 MPa. The integrated valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/s. The AC220V terminal coil is IP65 rated. For sizing, the safe working load is roughly 2356 N (60% of the 0.5 MPa push), allowing a 200kg vertical lift with a 2:1 margin. This SKU lacks a magnet, so it cannot take a magnetic switch.

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 SAUF100X250-08A Is Used
Heavy Stamp Ejection
Uses one coil signal to eject stamped parts directly at the press, removing the need for a remote valve manifold in a high-vibration cell.
Pallet Lift Station
Lifts heavy pallets with a 200kg vertical load margin, relying on the built-in 4M310 valve to decentralize control and save tubing runs.
Inline Divert Gate
Actuates a heavy divert gate on a packaging line, switching locally at 4 cycles/s without consuming a slot in the main distribution manifold.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-08A the Right Choice?
Size against the 63mm and 80mm neighbours: this 100mm bore provides 3927 N push at 0.5 MPa versus 2513 N for the 80mm. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT thread suit your control panel. The rod retracts when energised; reposition the valve to extend on signal. Without air, the valve routes flow but does not lock the piston, so add an external rod lock or pilot-operated check valve to hold suspended loads. For this 250mm stroke, fit guide rails to manage side 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 SAUF100X250-08A FAQ
It generates 3927 N push and 3681 N pull at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) running on AC220V. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
No, the built-in valve only routes air and does not lock the piston, so the load drifts on air loss; add an external rod lock for holding. Additionally, this specific SKU lacks a magnet (-S), so it cannot accept a magnetic switch.
