Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 125mm 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 SAUF32X125S-08A
The SAUF32X125S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 32 mm bore generates 402 N push and 345 N pull at 0.5 MPa. The cylinder body rates to 1.0 MPa, but the integrated valve limits operation to a 0.15-0.8 MPa window.
The integrated valve uses a 1/4" port with a flow of 16 mm2 (Cv 0.89) and reaches 5 cycles/sec. The AC220V terminal entry coil is IP65 rated with a 0.05 s response. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 241 N (60% of the 402 N push force), yielding a vertical lift capacity of about 20 kg with a 2:1 margin. The cylinder port is 1/8" and the rod thread is M10x1.25.

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 SAUF32X125S-08A Is Used
Component Ejection
Decentralized ejection of small molded parts where one coil signal per actuator avoids a central manifold.
Transfer Diverters
Routing packages on a conveyor line using local 4M210 valves to save tubing across long frames.
Clamp Stations
Independent clamping of small workpieces with CMSG sensors confirming position at each stop.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-08A the Right Choice?
Size this 32 mm bore against the 40 mm option: the 40 mm yields 628 N push at 0.5 MPa versus 402 N here. Confirm the AC220V terminal entry coil matches your supply. The rod retracts when energised by default; reposition the valve to extend on signal. The 4M210 valve routes air but does not lock the piston, so add an external rod lock or pilot-operated check valve to hold loads. Since the 125 mm stroke is under 300 mm, side-load guides are less critical. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating.
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 SAUF32X125S-08A FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in 4M210-08 valve has a 1/4" port, Cv 0.89, and runs on AC220V. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window.
The rod retracts when the coil is energised. You can reconfigure it to extend when energised by repositioning the integrated 4M210 valve. This local switching removes the need for a remote valve, simplifying installation.
