Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 800mm 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 SAUF40X800-06A
The SAUF40X800-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve mounted on the cap. One AC220V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. This SKU lacks a magnet (-S) and cannot take a magnetic switch.
It features a 40mm bore, 1/4" cylinder port, M12x1.25 rod thread, and 21mm adjustable cushions. The 4M210-06 valve port is 1/8" with a Cv of 0.78 and runs up to 5 cycles/sec. Operating pressure is 0.15-0.8 MPa. At 0.5 MPa it pushes 628N and pulls 528N. The computed safe working load is about 377N, allowing a vertical lift of roughly 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 SAUF40X800-06A Is Used
Divert Gate Actuation
Drives a routing flap on a packaging line directly from one coil signal, removing the need to trace tubing back to a central valve manifold.
Decentralized Pallet Stop
Raises and lowers a pallet stop in a large facility, saving manifold slots and simplifying installation across long distances.
Machine Guard Door
Opens and closes a heavy access door using the integrated 4M210 valve, cutting assembly time and reducing leak points.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X800-06A the Right Choice?
Size by comparing neighboring bores: the 32mm bore pushes 402N while the 50mm pushes 982N at 0.5 MPa. This 40mm bore yields 628N push and 528N pull at 0.5 MPa, safely within the 0.15-0.8 MPa valve window. Confirm the AC220V terminal entry and PT thread suit your control panel. Default action retracts the rod when energized, but you can reposition the valve to extend on signal. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads securely. Because the stroke is 800mm, use an external guide to prevent rod bending and side-load damage.
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 SAUF40X800-06A FAQ
It pushes 628N and pulls 528N 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 entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend on signal by repositioning the built-in valve. This self-switching design means no remote valve is needed.
