Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125-06A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 125mm 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 SAUF32X125-06A
The AirTAC SAUF32X125-06A is a double-acting profile cylinder with a built-in 4M210-06 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. This 32mm bore uses a 1/8" cylinder port and delivers 402N push at 0.5 MPa.
The integrated valve provides 1/8" porting, 14mm2 flow (Cv 0.78) and switches up to 5 cycles/sec. It operates on an AC220V terminal entry coil (IP65, response <=0.05s). Size within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Based on the 402N push at 0.5 MPa, the safe working load is ~241N, allowing a vertical lift of ~20kg with a 2:1 margin. This SKU lacks a magnet, so it cannot take 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 SAUF32X125-06A Is Used
Decentralized Clamping
Individual clamping stations on a large fixture use the built-in valve to actuate directly from one AC220V signal, cutting tubing runs.
Inline Diverters
Small package routing gates switch independently at up to 5 cycles/sec without crowding a central valve manifold.
Modular Pick & Place
Compact 32mm profile actuators handle 20kg vertical lifts in distributed assembly cells, saving manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125-06A the Right Choice?
Select by sizing both ways: this 32mm bore pushes 402N at 0.5 MPa, sitting between the smaller options and the 40mm bore (628N). Confirm the AC220V terminal entry coil and PT thread meet your supply. The rod retracts when energised; reposition the valve to extend on signal. The assembled unit operates at 0.15-0.8 MPa. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 125mm stroke, side-load is minimal, but for strokes >=300mm use a guide. This no-S model cannot accept sensors.
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 SAUF32X125-06A FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) on an AC220V terminal coil. Size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod on signal, but you can reposition the valve to extend when energised. Because the valve only routes air, use an external rod lock or pilot-operated check valve to hold a load.
