Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 150mm 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 SAUF32X150-08A
The AirTAC SAUF32X150-08A 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 has a 1/8" cylinder port and a 12mm rod with an M10x1.25 thread.
The integrated 4M210-08 valve features a 1/4" port, 16mm2 flow (Cv 0.89), and runs at 5 cycles/sec. It operates within a 0.15-0.8 MPa window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 402N and pulls 345N. A practical computed insight: the safe working load is roughly 241N, allowing a 2:1 margin to vertically lift about 20kg. The AC220V terminal entry coil is IP65 rated. Without a magnet suffix, this SKU 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 SAUF32X150-08A Is Used
Component Ejection
Decentralized ejection of small parts from a CNC machining center using one coil signal per actuator without a central manifold.
Sorting Diverter
A compact profile diverter on a packaging line that switches itself locally, saving tubing runs in tight machine frames.
Clamp Station
Independent clamping of workpieces at multiple assembly cells, where the built-in 4M210 valve simplifies installation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150-08A the Right Choice?
When sizing, compare neighbouring bores: a 40mm bore gives 628N push at 0.5MPa versus 402N here, while a 32mm is more compact. Confirm the AC220V terminal entry and PT thread match your supply. The assembled unit must operate within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. Default action retracts the rod when energised; reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads. For this 150mm stroke, ensure side-load guidance to prevent rod binding.
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 SAUF32X150-08A FAQ
It generates 402N push and 345N pull at 0.5MPa. The built-in 4M210-08 valve has a 1/4" port, Cv 0.89, and runs on AC220V. Size the force within the valve's 0.15-0.8MPa operating window, not the 1.0MPa cylinder body rating.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The valve routes air and is not a lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding.
