Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 80mm 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 SAUF40X80S-06A
The AirTAC SAUF40X80S-06A is a double-acting profile cylinder with a built-in 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 40mm bore delivers 628N push and 528N pull at 0.5 MPa, operating within the valve's 0.15-0.8 MPa range. The cylinder port is 1/4".
The integrated 4M210-06 valve features a 1/8" port, 14mm2 flow (Cv 0.78), and runs up to 5 cycles/sec. It uses an AC220V terminal entry coil (IP65, class B, 0.05s response). The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 377N, and vertical lift capacity is 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 SAUF40X80S-06A Is Used
Modular Clamping Station
Decentralized clamping on a machining line. The integrated valve switches the actuator directly from one coil signal, removing the need to run tubing back to a central manifold.
Inline Divert Gate
A sorting diverter on a conveyor. The built-in 4M210 valve handles the 5 cycles/sec actuation, while the compact profile saves space along the conveyor frame.
Package Pusher
Pushing cartons off a roller track. The AC220V coil provides reliable switching, and the magnetic piston allows position confirmation via reed switches.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X80S-06A the Right Choice?
Size this 40mm bore against the neighbouring 32mm and 50mm options. At 0.5 MPa it yields 628N push and 528N pull. Confirm the AC220V terminal entry and PT thread meet your control spec. The default action retracts the rod when energised; reposition the valve to extend on signal. Size force within the 0.15-0.8 MPa valve window, 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 loads safely. For this 80mm stroke side-load is minimal, but for strokes >=300mm guide the rod to prevent binding.
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 SAUF40X80S-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, 5/2 solenoid) running on an AC220V terminal coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. This self-switching design removes the need for a remote valve.
