Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 300mm 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 SAUF32X300-08B
The SAUF32X300-08B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote valves and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This SKU lacks a magnet and cannot take a magnetic switch.
It delivers 402 N push at 0.5 MPa within the valve's 0.15-0.8 MPa operating window. The 1/4" ported valve flows 16 mm2 (Cv 0.89) at up to 5 cycles/s. Computed buyer insight: safe working load is roughly 241 N (60% of the 0.5 MPa push), offering a 2:1 margin for a 20 kg vertical lift. The cylinder port is 1/8".

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 SAUF32X300-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station needs independent actuation without routing tubing back to a central manifold.
Inline Divert Gate
Perfect for a conveyor diverter requiring a single coil signal to actuate a 300 mm stroke gate directly at the mechanism.
Compact Ejector
Saves installation time on a packaging line ejector by integrating the 4M210 valve on the cap, eliminating extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300-08B the Right Choice?
Size by checking both neighbors: a 40 mm bore gives 628 N push at 0.5 MPa if 402 N is insufficient, while a 32 mm bore is the smallest available. This DC24V terminal entry coil must match your control voltage. The rod retracts when energized by default; reposition the valve to extend on signal. Size force strictly within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For the 300 mm stroke, use external guides to prevent rod bending from 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 SAUF32X300-08B 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, 5/2 solenoid) running on DC24V. Although the cylinder body rates to 1.0 MPa, size force within the assembled valve's 0.15-0.8 MPa operating window.
No. The built-in 5/2 valve only routes air; it is not a load lock. If air is lost, the piston drifts. To maintain a vertical load, add an external rod lock or a pilot-operated check valve.
