Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150S-08A is a genuine double-acting profile-type cylinder with a Ø32mm 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 SAUF32X150S-08A
The SAUF32X150S-08A 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 1/8" cylinder port, while the valve port is 1/4".
Operating in the 0.15-0.8 MPa valve window, it delivers 402 N push at 0.5 MPa. A practical computed insight: safe working load is roughly 241 N, and vertical lift is about 20 kg with a 2:1 margin. The AC220V terminal entry coil is IP65 rated, and the piston magnet supports CMSG/DMSG/EMSG switches. The valve flows 16 mm2 (Cv 0.89) at up to 5 cycles per second.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X150S-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station switches itself locally, avoiding a central valve manifold and long tubing runs.
Inline Diverters
Perfect for mounting directly onto a conveyor frame to actuate small diverters, saving manifold space and simplifying electrical wiring.
Compact Pick-and-Place
Suits tight assembly machine grids where the integrated valve and short profile barrel minimize the overall footprint.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150S-08A the Right Choice?
Size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. At 0.5 MPa this 32 mm bore pushes 402 N and pulls 345 N; if you need more force step up to the 40 mm bore (628 N push), or drop to a smaller actuator if 402 N is excessive. Confirm the AC220V terminal entry and PT threads suit your system. Default action retracts the rod when energised; reposition the valve to extend on signal. The built-in valve routes air and is not a load lock, so add an external rod lock or pilot-operated check valve for held loads. 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 SAUF32X150S-08A FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) driven by an AC220V terminal entry coil. Although the cylinder body rates to 1.0 MPa, size force within the valve's 0.15-0.8 MPa operating window.
The default action retracts the rod when energised. You can reconfigure it to extend on signal by repositioning the built-in valve. Because the valve only routes air, it is not a load lock, so use an external rod lock or pilot check valve if you need to hold a load.
