Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-10B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 400mm 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 SAUF100X400S-10B
The SAUF100X400S-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. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 100mm bore version uses a 1/2" cylinder port and includes a piston magnet for position sensing.
It delivers 3927N push and 3681N pull at 0.5MPa. The integrated valve has a 3/8" port, Cv 1.68 flow, and cycles up to 4 times per second. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. Based on the 0.5MPa push figure, the safe working load is about 2356N, yielding a 200kg vertical lift capacity 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 SAUF100X400S-10B Is Used
Heavy Press Clamping
Decentralized clamping in automated presses where the 100mm bore provides high force without routing long tubing to a central manifold.
Pallet Diverter
Independent diverting arms on a conveyor line benefit from the integrated valve, allowing one coil signal per actuator for fast installation.
Vertical Lift Gate
Lifting heavy gates in logistics hubs. The built-in 4M310 valve handles the 0.8MPa pressure window while saving manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400S-10B the Right Choice?
Size between the 80mm bore (2513N push at 0.5MPa) and this 100mm bore (3927N push). The 4M310-10 valve handles 0.15-0.8MPa; never size the assembled unit to the 1.0MPa body limit. Confirm the DC24V terminal entry and PT threads. The rod retracts when energised by default but can be reconfigured to extend by repositioning the valve. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 400mm stroke, use external guides to prevent rod bending and 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 SAUF100X400S-10B FAQ
It pushes 3927N and pulls 3681N at 0.5MPa. The built-in valve is a 4M310-10 with 3/8" port and Cv 1.68. It uses a DC24V coil. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa operating window.
No. The built-in 5/2 valve routes air but is not a load lock. The rod retracts when energised by default but can be reconfigured to extend by repositioning the valve. For load holding on air loss, add an external rod lock or pilot-operated check valve.
