Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-06A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 300mm 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 SAUF32X300S-06A
The SAUF32X300S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One AC220V coil signal drives the 32mm bore and 300mm stroke, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. The 1/8" valve port delivers 14 mm2 flow (Cv 0.78) at up to 5 cycles per second. The cylinder body rates to 1.0 MPa, but you must size force within the integrated valve's 0.15-0.8 MPa operating window. The bore's air port is 1/8" with a PT thread. This unit includes a piston magnet for CMSG/DMSG/EMSG switches.
At 0.5 MPa it pushes 402 N and pulls 345 N. A practical computed insight: plan for a safe working load around 241 N (about 60% of the 0.5 MPa push force), which suits a vertical lift of roughly 20 kg with a 2:1 safety margin. The coil uses terminal entry, and the recommended PU tube is Ø8xØ5.

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 SAUF32X300S-06A Is Used
Decentralized Clamping
Ideal for a multi-station clamping fixture where running individual air lines to a central manifold is impractical, letting this 32mm bore actuate independently via its built-in valve.
Inline Diverting
Perfect for a decentralized conveyor divert gate that switches up to 5 cycles per second without consuming a slot on the main machine valve manifold.
Remote Pick-and-Place
Suits a compact pick-and-place unit on a large assembly line, saving tubing and installation time by driving the 300mm stroke directly from one AC220V signal.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-06A the Right Choice?
When sizing, compare neighboring bores: a 40mm bore offers 628 N push at 0.5 MPa if your 241 N safe working load estimate is too tight, while this 32mm bore provides 402 N. Confirm your coil is AC220V with terminal entry before ordering. The rod retracts by default when energized, but you can reconfigure it to extend-when-energised by repositioning the valve. Always operate within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Because the built-in valve only routes air, it is not a load lock; add an external rod lock or pilot-operated check valve to hold a load safely. For this 300mm stroke, use external guides to prevent rod bending and side-load damage.
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 SAUF32X300S-06A FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa, reaching 643 N push at 0.8 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V 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.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. This allows you to choose the fail-safe direction for your application without extra plumbing.
