Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150-08B 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 SAUF32X150-08B
The SAUF32X150-08B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One DC24V coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It has a 1/8" cylinder port, M10x1.25 rod thread, and 21mm cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, this 32mm bore delivers 402N push and 345N pull at 0.5 MPa. The integrated 4M210-08 valve has a 1/4" port, Cv 0.89 flow, and handles 5 cycles/sec. For sizing, the safe working load is roughly 241N, and it can vertically lift about 20kg with a 2:1 margin. This terminal-entry, PT-threaded SKU lacks a magnet, so it cannot accept a sensor.

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 SAUF32X150-08B Is Used
Decentralized Clamping
Ideal for a clamping station where running a single DC24V signal to the cap valve is faster than plumbing a remote manifold.
Inline Diverting
A short-stroke diverter gate that benefits from the 5 cycles/sec speed of the 4M210 valve and the compact profile barrel.
Modular Pick-and-Place
Perfect for standalone gantry axes where saving manifold slots and minimizing tubing between the controller and cylinder is critical.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150-08B the Right Choice?
Size by force: this 32mm bore gives 402N push at 0.5 MPa, whereas the 40mm bore gives 628N. If your load is lighter, confirm if a smaller actuator works. Always size within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Verify you need DC24V terminal entry before ordering. The rod retracts when the coil energises; reposition the valve to invert this. Since this SKU lacks the -S suffix, it cannot take a magnetic switch. The valve routes air but does not lock the piston; add an external rod lock or pilot-operated check valve to hold a load. For this 150mm stroke, guide any side loads.
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 SAUF32X150-08B FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89) running on DC24V. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The 5/2 valve only routes air; it is not a load lock. If you need to hold a load against air loss, install an external rod lock or pilot-operated check valve.
