Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 225mm 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 SAUF40X225S-06A
The SAUF40X225S-06A 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 is shorter than an ISO 15552 cylinder of the same bore. This unit has a 225 mm stroke and a 1/4" cylinder port.
It delivers 628 N push at 0.5 MPa. For sizing, a safe working load is roughly 377 N, and it can vertically lift about 32 kg with a 2:1 margin. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78, and cycles up to 5 times per second. The coil is AC220V with terminal entry. Because the valve limits pressure, operate the assembled unit within 0.15-0.8 MPa, not the 1.0 MPa cylinder body rating. The S suffix means a piston magnet is included for CMSG/DMSG/EMSG switches.

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 SAUF40X225S-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving tubing runs back to a central manifold.
Inline Diverting
Mount directly on a conveyor diverter arm. The integrated valve handles 5 cycles per second, providing rapid sorting without remote plumbing delays.
Compact Ejection
Fits into tight machine frames for part ejection. The profile barrel keeps the footprint short, and the AC220V terminal entry simplifies wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225S-06A the Right Choice?
When sizing, compare this 40 mm bore against the 32 mm and 50 mm neighbors. The 40 mm yields 628 N push and 528 N pull at 0.5 MPa. Verify your coil is AC220V with terminal entry. The default action retracts the rod when energized; reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve window. The built-in valve routes air but is not a lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load. For this 225 mm stroke, guide the load to manage side-load forces.
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 SAUF40X225S-06A FAQ
It delivers 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) running on AC220V. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the valve's 0.15-0.8 MPa window.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend on signal by repositioning the valve. This self-switching design means no remote valve is needed.
