Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-06A 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 SAUF32X250-06A
The AirTAC SAUF32X250-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This 32mm bore uses a 1/8" cylinder port and a 1/8" valve port, flowing 14 mm2 (Cv 0.78) at up to 5 cycles per second.
Size force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 402 N and pulls 345 N. For sizing, the safe working load is about 241 N (60% of the 0.5 MPa push), and it can vertically lift roughly 20 kg with a 2:1 margin. This terminal-entry, PT-thread version has no magnet (-S omitted), 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 SAUF32X250-06A Is Used
Decentralized Clamping Station
Ideal for a multi-station machining line where each clamp needs its own direct AC220V signal without running tubing back to a central manifold.
Independent Diverter Gate
Perfect for a conveyor diverter that switches up to 5 times per second, using the integrated 4M210-06 valve to save space and plumbing.
Localized Package Stopper
Suits a packaging line stopper mechanism, driving the 32mm rod directly from one coil to isolate control at the point of operation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-06A the Right Choice?
When sizing, compare neighbouring bores: this 32mm bore pushes 402 N at 0.5 MPa, whereas a 40mm bore pushes 628 N. Confirm your coil is AC220V with terminal entry before ordering. The rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Always operate the assembled unit within the 0.15-0.8 MPa valve range, never at the 1.0 MPa cylinder body limit. The built-in valve only routes air, so add an external rod lock or pilot-operated check valve if you need to hold a load against air loss. For this 250mm stroke, guide the load to prevent excessive side-loading on the rod.
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 SAUF32X250-06A 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/s max) running on AC220V. You must size the force within the valve's 0.15-0.8 MPa operating window, not the cylinder body's 1.0 MPa limit.
No, this SKU lacks the -S suffix, so it has no magnet and cannot take a magnetic switch. Additionally, the built-in valve only routes air; it is not a lock. The piston will drift on air loss, so use an external rod lock or pilot-operated check valve to hold a load.
