Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-10A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 250mm stroke and a built-in 4M310-10 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 SAUF100X250-10A
The SAUF100X250-10A is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. It features a 1/2 inch cylinder port, an M20x1.5 rod thread, and 29 mm adjustable cushions.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers 3927 N push force at 0.5 MPa. A computed buyer insight suggests a safe working load of roughly 2356 N, or a vertical lift capacity of about 200 kg with a 2:1 margin. The integrated 4M310-10 valve has a 3/8 inch port, Cv 1.68 flow, and cycles up to 4 times per second. This AC220V terminal-entry coil is IP65 rated, and because this SKU lacks a magnet, it cannot accept 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 SAUF100X250-10A Is Used
Heavy Duty Clamping
Decentralized clamping on large machining fixtures where routing a remote valve to a 100 mm bore actuator would require excessive tubing.
Press Ejection
Independent ejection stations on a press line, using the built-in 4M310 valve to switch each cylinder directly without a central manifold.
Pallet Stopping
Heavy pallet stops on conveyors, leveraging the 3927 N push force at 0.5 MPa and one-signal actuation for simplified controls.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-10A the Right Choice?
Size this 100 mm bore against the 80 mm neighbor: the 100 mm provides 3927 N push at 0.5 MPa versus 2513 N on the 80 mm. If you do not need the extra thrust, step down to save space. Confirm the AC220V terminal entry and PT threads match your supply. The rod retracts when the coil is energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 250 mm stroke, ensure adequate side-load guidance to prevent rod damage.
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 SAUF100X250-10A FAQ
It generates 3927 N push and 3681 N pull at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in 4M310-10 valve has a 3/8 inch port, Cv 1.68, and runs on AC220V. You must size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body limit.
No, the built-in valve only routes air and is not a load lock; the piston will drift on pressure loss. For holding, install an external rod lock or pilot-operated check valve. By default the rod retracts when energized, but you can reposition the valve to extend on signal.
