Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-06B 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 SAUF32X250-06B
The AirTAC SAUF32X250-06B is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve on the cap. One DC24V 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. It has a 1/8" cylinder port, an M10x1.25 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, this 32mm bore delivers 402N push and 345N pull at 0.5MPa. The integrated valve flows 14mm2 (Cv 0.78) at up to 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-thread SKU lacks a magnet, so it cannot accept a magnetic switch.

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 SAUF32X250-06B Is Used
Decentralized Clamping
Ideal for a multi-station clamping fixture where running individual tubes back to a central manifold is impractical.
Independent Diverters
Perfect for a conveyor diverter gate that needs a single DC24V signal to actuate without dedicating a manifold slot.
Compact Part Ejection
Suits a small part ejection station on a dense machine bed where the integrated valve saves valuable space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-06B the Right Choice?
When sizing, compare neighbouring bores: this 32mm bore gives 402N push at 0.5MPa, whereas a 40mm bore yields 628N. Always size force within the 0.15-0.8 MPa valve range, never the 1.0MPa cylinder body rating. Confirm the DC24V terminal entry matches your control signal. The rod retracts by default when energised; you can reconfigure it to extend by repositioning the valve. 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 250mm stroke, guide the load to prevent side-load wear.
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 SAUF32X250-06B FAQ
It uses a 4M210-06 5/2 valve with a 1/8" port, 14mm2 flow (Cv 0.78), and a DC24V terminal-entry coil. The 32mm bore provides 402N push at 0.5MPa. You must size the force within the valve's 0.15-0.8 MPa operating window.
No, the 5/2 valve only routes air and is not a lock. The rod retracts when energised by default, but you can reposition the valve to extend on signal. For load holding, install an external rod lock or pilot-operated check valve.
