Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 450mm 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 SAUF32X450S-06B
The SAUF32X450S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, this 32 mm bore generates 402 N push at 0.5 MPa. The safe working load is roughly 241 N, and vertical lift is about 20 kg with a 2:1 margin. The 1/8" valve port yields 14 mm2 flow (Cv 0.78) at up to 5 cycles per second. The cylinder body rates to 1.0 MPa, but the assembled unit is limited by the valve. The 1/8" cylinder port and M10x1.25 rod thread are fixed by the bore.

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 SAUF32X450S-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station switches itself via a single DC24V signal, removing long tube runs back to a central manifold.
Inline Diverting
Perfect for a conveyor diverter arm; the integrated 4M210 valve handles 5 cycles per second for rapid part routing without extra plumbing.
Compact Ejection
Fits tightly in a packaging line ejector. The profile barrel saves space while the magnet allows CMSG sensors to confirm ejection strokes.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-06B the Right Choice?
Size by force: this 32 mm bore pushes 402 N at 0.5 MPa, sitting between the 50 mm bore (982 N) and smaller actuators. The 450 mm stroke is standard but long, so add external guides to prevent rod bending and side-load wear. The coil is DC24V with terminal entry. Default action retracts the rod when energised; reposition the valve to extend on signal. Size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; for load holding 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 SAUF32X450S-06B FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate in the 0.15-0.8 MPa valve window.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend on signal by repositioning the built-in valve. This self-switching design removes the need for a remote valve.
