Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X75S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X75S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 75mm 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 SAUF32X75S-08A
The SAUF32X75S-08A 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 actuator, eliminating remote plumbing and saving a manifold slot. The 32mm bore delivers 402N push and 345N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa range. The cylinder body rates to 1.0MPa, but the assembled unit is limited by the valve.
This model features a 1/4" valve port with 16mm2 flow (Cv 0.89) and switches up to 5 cycles per second. The piston rod is Ø12mm with an M10x1.25 thread, and the cylinder port is 1/8". Computed buyer insight: safe working load is roughly 241N (about 60% of the 402N push at 0.5MPa), allowing a vertical lift of approximately 20kg with a 2:1 margin. The S suffix denotes a built-in piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF32X75S-08A Is Used
Modular Assembly Stations
Ideal for decentralized clamping where one coil signal per actuator saves tubing and eliminates a central valve manifold.
Small Part Ejection
Provides rapid ejection with a 5 cycle/s frequency, fitting neatly into tight machine frames without remote plumbing.
Diverter Gates
Powers lightweight sorting flaps directly at the conveyor, using the integrated 4M210 valve for fast local switching.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X75S-08A the Right Choice?
Size by comparing neighbouring bores: the 32mm bore offers 402N push at 0.5MPa, whereas the 40mm bore offers 628N. Select this 75mm stroke model if your space is tight but requires more travel than the 50mm minimum. Confirm the AC220V terminal entry and PT thread suit your control panel. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8MPa valve window. The valve only routes air, so for load holding on air loss, add an external rod lock or pilot-operated check valve. For strokes of 300mm or more, ensure external side-load guidance.
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 SAUF32X75S-08A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on AC220V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No, the built-in valve routes air but is not a lock. The rod retracts when energised by default, but can be reconfigured to extend. For vertical load holding on air loss, you must add an external rod lock or pilot-operated check valve.
