Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 350mm 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 SAUF32X350S-08A
The SAUF32X350S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
At 0.5 MPa it pushes 402 N and pulls 345 N, operating within the valve's 0.15-0.8 MPa window. The 1/4" valve port gives 16 mm2 flow (Cv 0.89) at up to 5 cycles/s. The cylinder port is 1/8". Safe working load is roughly 241 N, allowing a 20 kg vertical lift with a 2:1 margin. The AC220V terminal coil is IP65 rated.

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 SAUF32X350S-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Diverting
Mounts directly on a conveyor diverter arm. The integrated valve eliminates tubing runs back to a central control block.
Package Sorting Gate
Perfect for a 350 mm sorting gate stroke. The AC220V coil provides fast 5 cycles/s actuation for high throughput.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-08A the Right Choice?
Size by checking both neighbors: the 40 mm bore offers 628 N push at 0.5 MPa, while this 32 mm bore gives 402 N. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT threads suit your supply. Default action retracts the rod when energised; reposition the valve to extend on signal. The built-in valve routes air but does not lock the load—add an external rod lock or pilot-operated check valve for holding. For the 350 mm stroke, use external guides to prevent rod bending and side loads.
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 SAUF32X350S-08A FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s) with an AC220V terminal coil. Size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the valve. This one-signal switching means no remote valve is needed.
