Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 125mm 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 SAUF50X125-06A
The SAUF50X125-06A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The bore 50mm cylinder port is 1/4" with an M16x1.5 rod thread. This compact profile is shorter than an ISO 15552 unit of the same bore.
Size force strictly within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 982N push and 825N pull. The safe working load is roughly 589N, and it can vertically lift about 50kg with a 2:1 margin. The integrated 4M210-06 valve has a 1/8" port, 14mm2 flow (Cv 0.78), and cycles up to 5 times per second. The AC220V terminal entry coil is IP65 rated. Lacking the S suffix, this SKU 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X125-06A 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
A single AC220V signal swings a divert gate on a packaging line, saving manifold space while providing rapid 5 cycle/sec actuation.
Compact Stopper Cylinder
Fits neatly into tight conveyor end-stops. The integrated valve minimizes exposed tubing in high-traffic dispatch areas.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125-06A the Right Choice?
Compare this 50mm bore (982N push at 0.5 MPa) against the 40mm bore (628N) or the 63mm bore (1559N) to match your load. The safe working load is approximately 589N. Confirm the AC220V terminal entry and PT thread suit your control panel. By default the rod retracts when the coil is energised; repositioning the valve changes it to extend-when-energised. Keep operating pressure between 0.15-0.8 MPa to match the valve, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold a load safely. For this 125mm stroke side-load is minimal, but any stroke over 300mm requires external guiding. Mounting accessories are compatible with the AirTAC SC series.
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 SAUF50X125-06A FAQ
It pushes 982N and pulls 825N 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. You must size force within the 0.15-0.8 MPa valve operating window, never the 1.0 MPa cylinder body limit.
The valve routes air but is not a lock, so the piston drifts on air loss; add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
