Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-06A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 250mm 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 SAUF32X250S-06A
The SAUF32X250S-06A is a compact 32mm profile-type double-acting 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 makes it shorter than an ISO 15552 cylinder of the same bore. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, it delivers 402 N push and 345 N pull at 0.5 MPa. The 4M210-06 valve has a 1/8" port, Cv 0.78, and runs up to 5 cycles/sec. The cylinder body rates to 1.0 MPa but the assembled unit is capped by the valve's 0.8 MPa limit. Computed buyer insight: safe working load is roughly 241 N (60% of the 0.5 MPa push), allowing a 20 kg vertical lift with a 2:1 margin.

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 SAUF32X250S-06A Is Used
Modular Clamping Stations
Decentralized clamping on a machining line. The integrated 4M210 valve switches the 32mm actuator directly from one AC220V signal, skipping a central manifold.
Package Diverter Gates
Routing small cartons on a conveyor. The compact profile cylinder fits tight transfer points, while the built-in valve minimizes tubing across the frame.
Multi-Zone Test Fixtures
Independent actuation for product testing. Each SAUF unit self-switches, saving manifold slots and simplifying I/O wiring for high-density test arrays.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250S-06A the Right Choice?
Size force across the 0.15-0.8 MPa valve range: this 32mm bore gives 402 N push at 0.5 MPa, whereas the neighbouring 40mm bore gives 628 N. Confirm your coil is AC220V with terminal entry before ordering. Default action retracts the rod when energised; reposition the valve to extend-when-energised. The built-in valve routes air, so add an external rod lock or pilot-operated check valve to hold a load. The cylinder air port is 1/8". For this 250mm stroke, guide the rod to manage side loads.
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 SAUF32X250S-06A FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) running on AC220V. Although the cylinder body rates to 1.0 MPa, size force within the valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised by repositioning the valve. Because the valve only routes air, use an external rod lock or pilot-operated check valve if you need to hold a load.
