Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 150mm stroke and a built-in 4M210-08 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-08B
The SAUF50X150S-08B 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 extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. The bore sets the 1/4" cylinder port and M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push and 825 N pull at 0.5 MPa. The safe working load is about 589 N, allowing a vertical lift of roughly 50 kg with a 2:1 margin. The integrated 4M210-08 valve has a 1/4" port, Cv 0.89, and cycles up to 5 times per second. 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-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses its own cylinder and valve, eliminating a central manifold.
Inline Diverters
Perfect for conveyor sorting arms that require individual actuation without routing long tube runs back to a main control panel.
Package Stops
Suits independent package stopping mechanisms on modular packaging lines, saving installation time and manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X150S-08B the Right Choice?
Size by comparing neighboring bores: the 40 mm bore gives 628 N push at 0.5 MPa, while the 63 mm bore gives 1559 N. This 50 mm bore provides 982 N push 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 DC24V terminal entry and PT thread meet your electrical specs. The rod retracts by default when energized, but you can reposition the valve to extend on signal. Because the valve only routes air, it is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 150 mm 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 SAUF50X150S-08B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in 4M210-08 valve has a 1/4" port, Cv 0.89, and a DC24V terminal coil. The assembled unit operates on 0.15-0.8 MPa, even though the cylinder body rates to 1.0 MPa.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the built-in valve. This self-switching design removes the need for a remote valve.
