Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 250mm 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 SAUF32X250S-06B
The SAUF32X250S-06B 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 is shorter than an ISO 15552 unit of the same bore. This 32 mm bore has a 1/8" cylinder port, an M10x1.25 rod thread, and 21 mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers 402 N push at 0.5 MPa. The 4M210-06 valve port is 1/8" with a Cv of 0.78 and cycles up to 5 times per second. The DC24V coil uses terminal entry, PT threads, and PU tube sized at Ø8xØ5. Based on the 0.5 MPa push force, the safe working load is roughly 241 N, translating to a vertical lift capacity of about 20 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 (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 SAUF32X250S-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 reducing tubing runs.
Inline Diverting
Perfect for a conveyor diverter gate that requires a compact profile cylinder with self-contained switching to minimize wiring across the frame.
Component Pushing
Suits a light assembly machine pushing 20 kg components vertically, utilizing the built-in 4M210 valve for fast 5 cycle/sec actuation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-06B the Right Choice?
Size by comparing neighboring bores: this 32 mm bore pushes 402 N at 0.5 MPa, whereas the 40 mm bore pushes 628 N. Confirm the DC24V coil and terminal entry match your control circuit. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG sensors. Since the 250 mm stroke exceeds 300 mm? No, but for any stroke ensure adequate side-load guidance. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve for load holding.
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 SAUF32X250S-06B FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in valve is a 4M210-06 with a 1/8" port and Cv of 0.78. The coil is DC24V with terminal entry. You must size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod upon energizing, but you can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This allows flexible machine sequencing without changing your electrical control signal.
