Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-10B 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 SAUF100X400-10B
The SAUF100X400-10B is a double-acting profile cylinder featuring an integrated AirTAC 4M 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 makes it shorter than an ISO 15552 cylinder of the same bore. This 100mm bore uses a 1/2" cylinder port and a 25mm rod with an M20x1.5 thread.
The built-in 4M310-10 valve provides 3/8" porting with a Cv of 1.68 and cycles up to 4 times per second. Operating on DC24V with terminal entry, the coil is IP65 rated. Size force within the valve's 0.15-0.8 MPa window, where it delivers 3927 N push at 0.5 MPa. A computed buyer insight: safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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)

| 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 SAUF100X400-10B Is Used
Heavy Stamping Press
Decentralized actuation for a heavy stamping station, using the integrated 4M310 valve to deliver high push force without a remote manifold.
Pallet Diverter
Single-signal routing for a 400mm stroke diverter arm on a packaging line, saving tubing and simplifying maintenance.
Vertical Lift Gate
Lifting a 200kg gate assembly using the 100mm bore, relying on the built-in valve for direct coil control.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-10B the Right Choice?
When sizing, compare this 100mm bore offering 3927 N push at 0.5 MPa against the neighboring 80mm bore which provides 2513 N. The 400mm stroke is well within the 1500mm maximum but requires external guidance to prevent rod bending under side loads. Confirm the DC24V terminal entry and PT threads suit your setup. The cylinder body rates to 1.0 MPa, but the assembled unit must operate at 0.15-0.8 MPa due to the valve. Default action retracts the rod when energized, but repositioning the valve changes it to extend-when-energized. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding.
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 SAUF100X400-10B FAQ
It generates 3927 N push and 3681 N pull at 0.5 MPa. The built-in valve is a 4M310-10 with a 3/8" port and Cv of 1.68. The DC24V coil operates at 0.15-0.8 MPa, even though the cylinder body rates to 1.0 MPa.
No, the built-in valve routes air but does not lock the piston. The rod retracts when energized by default, but can be reconfigured to extend. For load holding on air loss, install an external rod lock or pilot-operated check valve.
