Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350S-06B 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 SAUF40X350S-06B
The SAUF40X350S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210 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. The S suffix indicates a built-in piston magnet for CMSG/DMSG/EMSG switches.
This 40mm bore provides 628N push and 528N pull at 0.5MPa. The integrated valve operates strictly within a 0.15-0.8MPa window, even though the cylinder body rates to 1.0MPa. The 4M210-06 valve has a 1/8" port, 14mm2 flow (Cv 0.78), and handles up to 5 cycles/sec. The DC24V coil uses terminal entry and pairs with PU tube Ø8xØ5. Computed buyer insight: safe working load is roughly 377N (60% of the 0.5MPa push force), allowing a vertical lift of about 32kg 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 (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 SAUF40X350S-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, avoiding a central valve manifold.
Inline Divert Gate
Perfect for a 350mm divert gate on a packaging line, saving tubing by mounting the 4M210 valve directly on the cylinder cap.
Vertical Lift Stop
Suitable for a light 32kg vertical lift stop in a warehouse buffer, providing self-switching action without remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350S-06B the Right Choice?
Size this 40mm bore against the neighbouring 32mm (402N push @0.5MPa) and 50mm (982N push @0.5MPa) options. This model delivers 628N push at 0.5MPa. Confirm the DC24V terminal entry coil and PT thread match your control system. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8MPa valve limit. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve for held loads. For the 350mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF40X350S-06B FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by a DC24V terminal entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
No. The built-in valve only routes air; it is not a load lock. If air is lost, the piston drifts. For vertical load holding, install an external rod lock or a pilot-operated check valve. Also, the default retract-when-energised action can be changed to extend-when-energised by repositioning the valve.
