Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X400S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X400S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 400mm 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 SAUF40X400S-06A
The SAUF40X400S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 unit of the same bore. This model includes a piston magnet for CMSG/DMSG/EMSG switches.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa. The integrated valve has a 1/8" port, 14mm2 flow (Cv 0.78), and handles 5 cycles/sec. The cylinder body rates to 1.0MPa, but size force within the valve's 0.15-0.8MPa window. The safe working load is about 377N, allowing a vertical lift of roughly 32kg with a 2:1 margin. Coil is AC220V with terminal entry.

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 SAUF40X400S-06A Is Used
Conveyor Diverter Gate
Decentralized diverter on a packaging line. The built-in valve switches the 400mm stroke directly at the gate, removing long tube runs back to a central manifold.
Vertical Package Stopper
Independent stopper actuator on a sortation hub. One AC220V coil signal drives the 40mm bore, saving manifold space while providing 628N push at 0.5MPa.
Modular Machine Clamp
Individual clamping station on a large assembly machine. The integrated 4M210 valve allows standalone control without extra plumbing between stations.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X400S-06A the Right Choice?
Size by checking both neighboring bores: the 32mm bore yields 402N push while the 50mm bore yields 982N push at 0.5MPa. This 40mm unit provides 628N push, making it suitable for loads near 377N. Confirm the AC220V terminal entry and 1/4" cylinder port. The 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 to hold loads. For the 400mm 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 SAUF40X400S-06A FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 with a 1/8" port, Cv 0.78, and 5 cycles/sec max. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit operates at 0.15-0.8MPa.
The default action retracts the rod when the coil is energized. You can reconfigure it to extend-when-energized by repositioning the built-in valve. The valve routes air and is not a load lock, so use an external rod lock for holding.
