Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 250mm 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 SAUF32X250S-08A
The SAUF32X250S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The 32mm bore has a 1/8" cylinder port, a 12mm rod, and M10x1.25 rod-end thread. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
The integrated valve has a 1/4" port, 16mm2 flow (Cv 0.89), and cycles up to 5 times per second. The coil is AC220V with terminal entry. Size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 402N and pulls 345N. The computed safe working load is about 241N, and it can vertically lift roughly 20kg 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-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently without a central valve manifold.
Inline Diverting
Perfect for a conveyor diverter gate that requires a compact profile cylinder and self-contained switching to save tubing along the frame.
Package Sorting
Great for a sorting pusher that pushes light packages at up to 5 cycles per second with integrated AC220V control.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-08A the Right Choice?
Size against the 40mm bore if you need more force, or drop to a smaller profile if space is tighter. This 32mm bore delivers 402N push at 0.5 MPa. Confirm the AC220V terminal entry matches your supply. The rod retracts when the coil is energised; reposition the valve to make it extend-when-energised. Operate within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock, so add an external rod lock or pilot-operated check valve to hold a load. For this 250mm stroke, use a guide to prevent side-loading damage.
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-08A FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-08 with a 1/4" port, Cv 0.89, and runs on AC220V. You must size force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
No. The built-in 5/2 valve routes air but does not lock the piston. If air is lost the rod drifts. For load holding you must add an external rod lock or a pilot-operated check valve. The default action retracts the rod when energised, which you can change to extend by repositioning the valve.
