Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-10B 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 SAUF100X250S-10B
The SAUF100X250S-10B 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 in decentralized setups. The 100mm bore has a 1/2" air port, a 25mm rod, and 29mm adjustable cushions. An integrated piston magnet supports CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, it delivers 3927 N push and 3681 N pull at 0.5 MPa. The 4M310-10 valve provides 3/8" ports, Cv 1.68, and 4 cycles/sec. For sizing, the safe working load is roughly 2356 N (60% of the 0.5 MPa push), allowing a 200 kg vertical lift with a 2:1 margin. The DC24V terminal coil is IP65 rated.

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 SAUF100X250S-10B Is Used
Decentralized Press Clamping
Ideal for large presses needing individual clamping actuators. The built-in valve provides local control without long tubing runs back to a central manifold.
Heavy Material Diversion
Handles heavy product diversion on conveyors. One coil signal directly switches the 100mm bore, delivering 3927 N push for positive routing.
Pallet Positioning Stops
Perfect for robust pallet stops in high-throughput warehouses. The integrated magnet allows precise end-of-stroke detection for automated controls.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-10B the Right Choice?
Size by checking both neighbouring bores: the 80mm bore yields 2513 N push, while this 100mm bore provides 3927 N at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread suit your control system. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 250mm stroke, ensure adequate side-load guidance.
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 SAUF100X250S-10B FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/sec max). The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa operating window. The coil is DC24V with terminal entry.
No. The built-in 5/2 valve routes air but does not lock the piston. If air is lost, the load drifts. For load holding, install an external rod lock or a pilot-operated check valve. The rod retracts when energised by default, but you can reposition the valve to extend-when-energised.
