Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150S-08B 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 SAUF32X150S-08B
The SAUF32X150S-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 plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. The bore dictates a 1/8" cylinder port and an M10x1.25 rod thread.
Driven by a DC24V coil with terminal entry, the integrated valve offers 1/4" porting, 16 mm2 flow (Cv 0.89), and 5 cycles/sec. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 402 N and pulls 345 N. A computed buyer insight: safe working load is roughly 241 N (60% of the 0.5 MPa push), and vertical lift is about 20 kg with a 2:1 margin. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.

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 SAUF32X150S-08B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station switches itself via one DC24V signal, removing the need for a central valve manifold.
Inline Divert Gate
Perfect for a conveyor diverter that needs independent actuation without running long tubing back to a main control panel.
Compact Part Ejector
Fits space-constrained assembly machines, using the built-in valve and profile barrel to eject small parts efficiently.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X150S-08B the Right Choice?
Size this 32 mm bore against the 40 mm bore (628 N push at 0.5 MPa) if you need more force, or step down if less is required. Confirm the DC24V coil and terminal entry suit your control system. The rod retracts when energised by default; reposition the valve to extend-when-energised. Operate strictly within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The integrated valve routes air but does not lock the piston; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 150 mm 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 SAUF32X150S-08B FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) driven by a DC24V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default, the rod retracts when the coil receives a signal. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design means no remote valve is needed.
