Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 175mm 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 SAUF50X175S-06A
The SAUF50X175S-06A 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, eliminating remote plumbing and saving a manifold slot. The 50mm bore has a 1/4" cylinder port, a 20mm rod, and M16x1.5 rod-end thread. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and cycles up to 5 times per second. The AC220V terminal-entry coil is IP65 rated. Although the cylinder body rates to 1.0 MPa, the valve limits operation to 0.15-0.8 MPa. Push force is 982 N at 0.5 MPa. A safe working load is roughly 589 N, allowing a vertical lift of about 50 kg 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 (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 SAUF50X175S-06A Is Used
Conveyor Diverter Gate
Uses one AC220V signal to swing a diverter on a packaging line, removing the need for a central valve manifold and long tube runs.
Decentralized Clamp Station
Clamps pallets independently at multiple machine cells. The built-in 4M210 valve ensures rapid local actuation without complex plumbing.
Component Pusher Unit
Pushes parts into a machining fixture. The 50mm bore provides 982 N push force at 0.5 MPa, with the S suffix allowing position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-06A the Right Choice?
Size by checking both neighbouring bores: a 40mm bore gives 628 N push at 0.5 MPa, while a 63mm bore gives 1559 N. This 50mm bore yields 982 N push and 825 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT threads suit your supply. The rod retracts when the coil is energised, but you can reposition the valve to extend on energisation. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 175mm stroke, ensure adequate side-load guidance.
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 SAUF50X175S-06A FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78) with an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the valve. Because the valve only routes air, it is not a load lock; use an external rod lock or pilot-operated check valve if you need to hold a load.
