Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 225mm 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 SAUF32X225S-06B
The SAUF32X225S-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. The 225 mm stroke is above the 50 mm minimum and well within the 1000 mm max. An S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
The integrated valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and handles 5 cycles/sec. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly at 0.15-0.8 MPa. At 0.5 MPa it pushes 402 N and pulls 345 N. The computed safe working load is roughly 241 N, and it can vertically lift about 20 kg with a 2:1 margin. The 32 mm bore uses a 1/8" cylinder port, a Ø12 mm rod, and an M10x1.25 thread.

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 SAUF32X225S-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses its own SAUF cylinder, eliminating a central manifold and long tubing runs.
Inline Diverter Gate
Perfect for a conveyor diverter that needs a single coil signal to actuate a 225 mm stroke gate without complex remote valve wiring.
Modular Pick-and-Place
Suits a compact assembly module where the built-in valve saves manifold space and the magnet allows position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-06B the Right Choice?
Size by force: this 32 mm bore pushes 402 N at 0.5 MPa; step up to a 40 mm bore for 628 N if needed. The 225 mm stroke is standard and non-magnetic variants cannot take sensors. Confirm the DC24V terminal entry and PT threads. Default action retracts the rod when energised; reposition the valve to extend on signal. Size force within the 0.15-0.8 MPa valve limit, never the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 225 mm stroke, guide the load to manage side-load stress.
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 SAUF32X225S-06B FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) running on DC24V. The cylinder body rates to 1.0 MPa, but you must size force within the assembled valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve. Because the valve only routes air, use an external rod lock or pilot-operated check valve if you need to hold a load.
