Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 450mm 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 SAUF32X450S-08A
The SAUF32X450S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 makes it shorter than an ISO 15552 unit of the same bore. It features a 450mm stroke, a 1/8" cylinder port, and an M10x1.25 rod thread.
The integrated valve handles flow up to 16 mm2 (Cv 0.89) at 5 cycles/s. The coil is AC220V with terminal entry and IP65 protection. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within the 0.15-0.8 MPa valve window. At 0.5 MPa it delivers 402 N push force, giving a computed safe working load of roughly 241 N or a 20 kg vertical lift with a 2:1 margin. The S suffix adds a piston magnet for position sensing.

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-08A Is Used
Decentralized Clamping
Ideal for isolated clamping stations on a large machine bed where running individual lines back to a central manifold is impractical.
Inline Diverting
Mounts directly over a conveyor to actuate a diverter gate, using the integrated valve to switch instantly without extra tubing.
Compact Ejection
Fits tight ejection zones on packaging lines, saving manifold space while providing reliable 402 N push force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-08A the Right Choice?
Size by force: the 32mm bore yields 402 N push at 0.5 MPa, while the neighboring 40mm bore offers 628 N. Keep operating pressure within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry matches your supply. The rod retracts when energized by default but can be reconfigured to extend by repositioning the valve. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 450mm stroke, use external guides to prevent rod bending and side-load wear.
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-08A FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (Cv 0.89, 16 mm2 flow) operating at 5 cycles/s. The coil is AC220V with terminal entry. You must size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when the coil is energized, but you can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This allows flexible machine sequencing without altering your electrical control logic.
