Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 100mm 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 SAUF40X100-06A
The AirTAC SAUF40X100-06A is a double-acting profile cylinder with a built-in 4M210 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It uses a 1/4" cylinder port and an M12x1.25 rod thread.
Within the 0.15-0.8 MPa valve operating window, it delivers 628 N push at 0.5 MPa. A practical computed insight suggests a safe working load around 377 N, or a 32 kg vertical lift with a 2:1 margin. The integrated valve flows 14 mm2 (Cv 0.78) via a 1/8" port, cycling up to 5 times per second. The coil is AC220V with terminal entry. Note this SKU lacks a magnet, so it cannot take a magnetic switch.

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 SAUF40X100-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, skipping a central valve manifold.
Inline Divert Gate
Perfect for a conveyor diverter that needs a self-contained actuator; the built-in valve keeps response times under 0.05 s without long tube runs.
Package Stopper Arm
Suits a packaging line stop gate, saving installation time by integrating the 4M210 valve directly on the cylinder cap for local switching.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-06A the Right Choice?
Size by force: this 40 mm bore gives 628 N push at 0.5 MPa, sitting between the 50 mm (982 N) and 32 mm (402 N) options. Confirm the AC220V terminal coil matches your supply. Default action retracts the rod when energised; reposition the valve to extend instead. Size strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air but does not lock the piston, so add an external rod lock or pilot-operated check valve to hold a load. For this 100 mm stroke, side-load guides are not critical, but ensure alignment for smooth cushioning.
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 SAUF40X100-06A FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) running on AC220V with terminal entry. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
Yes, the default action retracts the rod when energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. If power or air drops, the piston drifts, so fit an external rod lock or pilot-operated check valve for holding.
