Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 700mm 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 SAUF40X700S-06A
The SAUF40X700S-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 40mm bore version features a 1/4" cylinder port, a 1/8" valve port, and a piston magnet for position sensing.
Operating within the valve's 0.15-0.8 MPa window, it delivers 628N push and 528N pull at 0.5 MPa. The integrated valve flows 14 mm2 (Cv 0.78) at up to 5 cycles per second. For sizing, the safe working load is roughly 377N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 32kg with a 2:1 safety margin. The AC220V terminal coil is IP65 rated with a response under 0.05 seconds.

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 SAUF40X700S-06A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The built-in 4M210-06 valve triggers the 700mm stroke locally, eliminating long tube runs back to a central manifold.
Independent Stack Pusher
Ideal for a standalone palletizing cell where one coil signal extends the rod to push cartons. The self-contained AC220V valve simplifies wiring and frees up manifold space.
Long-Reach Part Ejector
Suits injection molding ejector duties. The 700mm stroke reaches deep into the mold, while the magnetic piston allows CMSG sensors to confirm ejection completion.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-06A the Right Choice?
When sizing, compare neighbouring bores: the 32mm bore yields 402N push at 0.5 MPa, while the 50mm bore provides 982N. This 40mm bore gives 628N push and 528N pull at 0.5 MPa. Confirm the electrical setup: this model uses an AC220V terminal entry coil. Default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the 700mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load wear. The integrated valve routes air; it does not lock the load. For suspended loads, add an external rod lock or pilot-operated check valve to prevent drift on air loss.
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 SAUF40X700S-06A FAQ
It delivers 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
Yes. The default factory setting retracts the rod when the coil receives a signal. You can reconfigure it to extend-when-energised simply by repositioning the built-in 5/2 valve on the cap. This self-switching design means no remote valve is needed.
