Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 75mm 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 SAUF40X75-06A
The AirTAC SAUF40X75-06A 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 makes it shorter than an ISO 15552 cylinder of the same bore. It features a 16mm rod, M12x1.25 rod thread, and 1/4" cylinder port.
Operating within the 0.15-0.8 MPa valve window, it delivers 628N push force at 0.5 MPa. The integrated valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and handles 5 cycles/sec. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 377N, allowing a vertical lift of 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 SAUF40X75-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station needs independent actuation without routing long tube runs back to a central manifold.
Inline Divert Gate
Perfect for a conveyor diverter requiring a self-contained actuator; the built-in valve ensures rapid local switching without manifold dependencies.
Package Stopper Arm
Suits packaging lines needing a compact stopper arm, saving manifold space while delivering 628N push force directly at the point of operation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-06A the Right Choice?
Size by comparing neighbouring bores: the 32mm bore yields 402N push at 0.5 MPa, while the 50mm bore yields 982N. This 40mm bore provides 628N push and 528N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT thread meet your electrical specs. By default the rod retracts when energised; repositioning the valve changes this to extend-when-energised. Because this SKU lacks a magnet, it cannot take a magnetic switch. The valve routes air but does not function as a load lock—add an external rod lock or pilot-operated check valve to hold loads. For this 75mm stroke, side-load guides are not strictly required, but ensure proper alignment.
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 SAUF40X75-06A 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) driven by an AC220V terminal entry coil. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
No, the built-in valve only routes air and is not a lock. The rod drifts on air loss. To hold a load securely, you must add an external rod lock or a pilot-operated check valve. Also, this non-magnet SKU cannot accept magnetic sensors.
