Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125-06B 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 SAUF50X125-06B
The SAUF50X125-06B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One 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. It uses a 50mm bore with a 1/4" air port and an M16x1.5 rod thread.
Operating within the valve's 0.15-0.8 MPa range, it delivers 982N push and 825N pull at 0.5 MPa. 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, Cv 0.78 flow, and switches up to 5 cycles/sec. This DC24V terminal entry coil is IP65 rated. Since this SKU lacks a magnet, 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 (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 SAUF50X125-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space and tubing runs.
Inline Diverters
Perfect for a conveyor diverter gate that requires a self-contained 50mm bore actuator switching at up to 5 cycles per second without a remote valve bank.
Package Stops
Suits decentralized package stopping mechanisms on a sorting line, utilizing the built-in valve to simplify electrical control wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125-06B the Right Choice?
Size by checking both neighboring bores: a 40mm bore gives 628N push at 0.5MPa, while a 63mm bore gives 1559N. This 50mm bore provides 982N push. Always size force within the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT threads meet your specs. By default the rod retracts when energized, but repositioning the valve changes it to extend-when-energized. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads. For this 125mm stroke, side-load guides are unnecessary, but ensure standard SC-series mounting accessories fit your frame.
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 SAUF50X125-06B FAQ
It delivers 982N push and 825N pull at 0.5MPa using a 50mm bore. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) with a DC24V terminal entry coil. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
No remote valve is needed; the integrated 4M 5/2 valve switches the cylinder from one coil signal. It cannot hold a load on air loss because the valve only routes air. For load holding, install an external rod lock or pilot-operated check valve.
