Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 400mm 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 SAUF32X400S-08B
The SAUF32X400S-08B is a double-acting profile cylinder with a built-in AirTAC 4M 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 cylinder of the same bore. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
This 32 mm bore pushes 402 N at 0.5 MPa within the 0.15-0.8 MPa valve window. The integrated 4M210-08 valve has a 1/4" port, Cv 0.89, and handles 5 cycles/sec. The cylinder port is 1/8". Computed buyer insight: safe working load is roughly 241 N, and vertical lift is about 20 kg with a 2:1 margin. Coil is DC24V with terminal entry.

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 SAUF32X400S-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Divert Gate
Operates a short-stroke divert gate on a conveyor directly at the point of action, removing long tubing runs back to a central valve.
Component Pusher
Pushes lightweight parts out of a magazine at up to 5 cycles/sec without needing a separate remote 4M210 valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-08B the Right Choice?
Size both ways: this 32 mm bore delivers 402 N push at 0.5 MPa, sitting between the 40 mm (628 N) and smaller options. Confirm the DC24V coil and terminal entry suit your control system. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa valve window. Default action retracts the rod when energised; reposition the valve to extend on signal. The valve routes air and is not a load lock, so add an external rod lock or pilot-operated check valve to hold loads. For the 400 mm stroke, use external guides to prevent rod bending and side-load 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 SAUF32X400S-08B FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in valve is a 4M210-08 with a 1/4" port and Cv 0.89. The coil is DC24V. You must size the force within the 0.15-0.8 MPa valve operating window, even though the cylinder body rates to 1.0 MPa.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend when energised by repositioning the built-in valve. This self-switching design means no remote valve is needed.
