Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 150mm 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 SAUF50X150S-06B
The SAUF50X150S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 is shorter than an ISO 15552 cylinder of the same bore, and the 1/4" cylinder port is fixed by the 50mm bore.
The integrated valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and switches up to 5 cycles/sec. It operates at 0.15-0.8 MPa, so size force within that window rather than the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 982 N and pulls 825 N. This yields a safe working load of about 589 N, or a 50 kg vertical lift with a 2:1 margin. The DC24V terminal coil is IP65 rated, and the S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF50X150S-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 Diverting
Perfect for a conveyor diverter gate that requires rapid localized switching at 5 cycles/sec without routing air lines back to a central control panel.
Package Sorting
Suited for decentralized package routing arms in a logistics hub, using the built-in valve to minimize installation complexity across multiple lanes.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-06B the Right Choice?
Size by checking both neighbor bores: the 40mm bore offers 628 N push at 0.5 MPa, while the 63mm bore provides 1559 N. This 50mm bore gives 982 N push and 825 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT thread meet your electrical specs. The default action retracts the rod when energized, but you can reposition the valve to extend on energization. Always size force within the 0.15-0.8 MPa valve operating range. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 150mm stroke, ensure adequate side-load guidance to prevent rod damage.
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 SAUF50X150S-06B FAQ
It generates 982 N push and 825 N pull at 0.5 MPa using a built-in 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/sec). The DC24V terminal coil is IP65 rated. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod upon energization, but you can reconfigure it to extend when energized by repositioning the built-in valve. This self-switching design eliminates the need for a separate remote valve.
