Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 300mm 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 SAUF32X300-06B
The SAUF32X300-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One DC24V 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. This 32mm bore uses a 1/8" cylinder port, a 1/8" valve port, and a Ø12mm rod with an M10x1.25 thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers 402N push force at 0.5 MPa. The integrated valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/sec. For sizing, the safe working load is roughly 241N (60% of the 0.5 MPa push), and it can vertically lift about 20kg with a 2:1 margin. This terminal-entry, PT-threaded unit has no magnet and cannot accept a sensor.

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 SAUF32X300-06B Is Used
Decentralized Clamping Station
Ideal for a multi-station machining line where each clamp needs its own DC24V signal without running tubing back to a central manifold.
Inline Divert Gate
Uses the built-in 4M210 valve to actuate a 300mm divert gate at up to 5 cycles/sec, saving manifold space on the conveyor frame.
Independent Package Stopper
A standalone stopper cylinder on a packing line that switches itself locally, reducing plumbing complexity across the machine.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300-06B the Right Choice?
Size by checking both neighboring bores: this 32mm bore pushes 402N at 0.5 MPa, while the 40mm bore pushes 628N. Confirm the DC24V coil and terminal entry match your control voltage. The cylinder body rates to 1.0 MPa, but you must size force within the 4M210 valve's 0.15-0.8 MPa operating range. By default the rod retracts when energized; repositioning the valve switches it to extend-when-energized. Because this SKU lacks the -S magnet, it cannot take a magnetic switch. At 300mm stroke, add external guides to prevent rod bending and side-load wear. The valve only routes air; it is not a lock. To hold a load on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF32X300-06B 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, 5/2 solenoid) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
The valve routes air but does not lock the piston; on air loss the load drifts and the 21mm cushion only decelerates near stroke end. For holding, add an external rod lock or pilot-operated check valve. The rod retracts when energized by default, but you can reposition the valve to extend-when-energized.
