Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-06A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 50mm 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 SAUF32X50-06A
The AirTAC SAUF32X50-06A is a double-acting profile cylinder with a built-in 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. This 32mm bore uses a 1/8" cylinder port and generates 402N push at 0.5MPa.
The integrated 4M210-06 valve flows 14mm2 (Cv 0.78) and cycles up to 5 times per second. It operates within a 0.15-0.8MPa window, even though the cylinder body rates to 1.0MPa. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 241N, and it can vertically lift about 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 SAUF32X50-06A Is Used
Modular Assembly Cells
Distributes individual actuator control across large machines without routing long tube runs back to a central manifold.
Small Part Ejection
Provides rapid 5 cycle/sec ejection of small parts directly at the fixture using the integrated 4M210 valve.
Clamp Stations
Delivers 241N safe working clamping force locally, simplifying installation by combining valve and cylinder.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-06A the Right Choice?
Size by force: this 32mm bore pushes 402N at 0.5MPa, sitting between the 40mm bore (628N) and smaller actuators. The 50mm stroke meets the 50mm minimum for this bore. Confirm the AC220V terminal coil and PT thread suit your control panel. The valve runs at 0.15-0.8MPa, so never size the assembled unit at the 1.0MPa cylinder body limit. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Without air, the valve routes flow but does not lock the piston; add an external rod lock or pilot-operated check valve to hold loads. This SKU lacks a magnet and cannot take a sensor. For strokes over 300mm, use side-load guides.
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 SAUF32X50-06A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78) driven by an AC220V terminal coil. The assembled unit must operate within the valve's 0.15-0.8MPa pressure window, not the 1.0MPa 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 built-in valve. Because the valve only routes air, it cannot hold a load without air pressure; add an external rod lock for secure holding.
