Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-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 SAUF100X250S-10A
The SAUF100X250S-10A is a double-acting profile-type cylinder with a built-in AirTAC 4M 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 100mm bore has a 1/2" air port, a 25mm rod, and an M20x1.5 rod-end thread. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
The integrated 4M310-10 valve features a 3/8" port, Cv 1.68 flow, and 4 cycles/s. The coil is AC220V with terminal entry. Size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 3927 N, giving a safe working load of roughly 2356 N and a vertical lift capacity of about 200 kg with a 2:1 margin.

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-10A Is Used
Heavy Press Station
Decentralized pressing in a large machine. The built-in valve delivers one-signal actuation without running long tubing back to a central manifold.
Pallet Diverter
High-force sorting on a conveyor line. The integrated 4M310 valve handles the 100mm bore flow directly at the actuator, simplifying installation.
Vertical Lift Gate
Lifting heavy gates in a logistics hub. The 100mm bore provides 3927 N at 0.5 MPa, driven entirely by the cap-mounted solenoid valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-10A the Right Choice?
Select by comparing neighbours: the 80mm bore pushes 2513 N at 0.5 MPa, while this 100mm bore pushes 3927 N. Confirm the AC220V terminal entry and PT thread. The cylinder body rates to 1.0 MPa, but the assembled unit must operate in the 0.15-0.8 MPa valve range. The valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve to hold position. For this 250mm stroke, which is under the 300mm side-load threshold, standard mounting is fine. The default action retracts when energised; reposition the valve to extend on signal.
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-10A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in valve is a 4M310-10 with a 3/8" port and Cv 1.68. The coil is AC220V with terminal entry. You must size force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa.
By default the rod retracts when the coil receives a signal. You can reconfigure the actuator to extend-when-energised simply by repositioning the built-in valve. This self-switching design means no remote valve is needed, saving tubing and a manifold slot.
