Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 400mm stroke and a built-in 4M310-08 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 SAUF100X400-08A
The SAUF100X400-08A 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 unit has a 1/2" cylinder port, a 1/4" valve port, and a 400mm stroke.
It delivers 3927N push and 3681N pull at 0.5MPa. Size within the 0.15-0.8MPa valve window, as the cylinder body rates to 1.0MPa but the valve limits the assembly. The safe working load is roughly 2356N (60% of the 0.5MPa push), offering a vertical lift capacity of about 200kg with a 2:1 margin. The 4M310-08 valve flows 25mm2 (Cv 1.4) at up to 4 cycles/s. It uses an AC220V terminal entry coil (IP65, class B). Without a magnet suffix, this SKU cannot take 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 SAUF100X400-08A Is Used
Heavy Stamping Press
Applies 3927N of push at 0.5MPa for localized part forming, switching directly from its built-in valve without a central manifold.
Pallet Lift Station
Lifts roughly 200kg vertically using the 100mm bore, relying on the self-contained 4M310 valve for rapid decentralized actuation.
Diversion Gate
Drives a heavy routing flap at up to 4 cycles/s, saving tubing by mounting the AC220V solenoid directly on the cylinder cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X400-08A the Right Choice?
When sizing, compare neighbouring bores: an 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore provides 3927N. Confirm the AC220V terminal entry and PT threads meet your control specs. The rod retracts when the coil is energised, but you can reposition the valve to extend on signal. Always operate within the 0.15-0.8MPa valve pressure range. The valve only routes air, so for load holding on air loss, add an external rod lock or pilot-operated check valve. For the 400mm stroke, use external guides to prevent rod bending and side-load wear. Mounting uses AirTAC SC series accessories.
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 SAUF100X400-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25mm2 flow) running an AC220V terminal coil. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa operating window.
The 5/2 valve routes air and is not a lock, so the piston drifts on air loss. For held loads, add an external rod lock or pilot-operated check valve. By default the rod retracts when energised, but you can reposition the valve to extend on signal. It saves a manifold slot by switching itself.
