Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-06A 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-06A
The SAUF32X450S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One AC220V 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. This 32mm bore version has a 1/8" cylinder port, an M10x1.25 rod thread, and a 450mm stroke.
Operating within the valve's 0.15-0.8 MPa window, it delivers 402N push and 345N pull at 0.5MPa. The valve flows 14mm2 (Cv 0.78) at up to 5 cycles/sec. A safe working load is roughly 241N, offering a 2:1 vertical lift margin of about 20kg. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches. Note the 1.0MPa cylinder body rating is capped by the 0.8MPa valve limit.

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-06A Is Used
Compact Part Ejection
Decentralized ejection on a machining line. The built-in valve handles 5 cycles/sec directly at the actuator, clearing parts without a remote manifold.
Transfer Line Diverting
One-signal diverting along a conveyor. The AC220V coil switches the 450mm stroke locally, saving tubing runs and simplifying machine layout.
Small Component Sorting
Sorting stations benefit from the integrated 4M210 valve. The 32mm bore provides precise 241N working force for pushing light components reliably.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450S-06A the Right Choice?
Size by checking both neighbors: the 40mm bore offers higher force, while this 32mm bore provides 402N push at 0.5MPa. Confirm the AC220V terminal entry and PT threads match your supply. Default action retracts the rod when energized, but repositioning the valve switches it to extend-when-energized. Always size force within the 0.15-0.8MPa valve range, never the 1.0MPa body rating. Because the 450mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. The valve only routes air; it is not a load lock, so add an external rod lock or pilot-operated check valve to hold a load.
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-06A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by an AC220V terminal coil. Despite the 1.0MPa cylinder body rating, the assembled unit must operate at 0.15-0.8MPa due to the valve limit.
Yes, the default action retracts the rod when energized, but you can reposition the valve to make it extend instead. The 5/2 valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve for load holding.
