Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 350mm stroke and a built-in 4M210-06 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 SAUF40X350-06A
The SAUF40X350-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The hard-anodized aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. The cylinder port is 1/4" and the valve port is 1/8".
Operating within the valve's 0.15-0.8 MPa window, it delivers 628 N push and 528 N pull at 0.5 MPa. The safe working load is roughly 377 N, allowing a vertical lift of about 32 kg with a 2:1 margin. The valve flows 14 mm2 (Cv 0.78) at up to 5 cycles per second. Without a magnet, this SKU cannot take 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X350-06A Is Used
Diverter Gate Actuation
Drives a sorting flap directly at the conveyor lane using one AC220V signal, cutting tubing runs to a central manifold.
Independent Clamp Station
Holds a workpiece in a decentralized cell. The integrated 4M210-06 valve switches the clamp without occupying a manifold slot.
Carton Flap Folder
Folds flaps on a moving line. The compact profile fits tight machine frames while the 1/4" cylinder port delivers ample flow.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-06A the Right Choice?
Size between the 32 mm bore (402 N push) and the 50 mm bore (982 N push) to match your load. This 40 mm bore gives 628 N push at 0.5 MPa. Confirm the AC220V terminal entry and PT thread suit your control system. The default action retracts the rod when energised; reposition the valve to extend on signal. Size force strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold a load. At 350 mm 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 SAUF40X350-06A FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) with an AC220V terminal coil. Size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
Yes. The default action retracts the rod on signal, but you can reposition the built-in valve to make the rod extend when energised. This gives you flexible control without needing a separate remote valve.
