Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-08A is a genuine double-acting profile-type cylinder with a Ø50mm 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 SAUF50X75S-08A
The AirTAC SAUF50X75S-08A is a double-acting profile cylinder with a built-in 4M210-08 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 means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, it delivers 982 N push and 825 N pull at 0.5 MPa. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) with a 5 cycle/s limit. The cylinder port is 1/4" with a PT thread. For sizing, expect a safe working load around 589 N, or a 50 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X75S-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently without a central manifold.
Inline Diverter Gate
Perfect for a conveyor diverter that needs a self-contained actuator, saving tubing and simplifying installation along the line.
Package Stopper Arm
Suits a logistics sorting hub where individual stop arms must switch rapidly without routing extra air lines back to a panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-08A the Right Choice?
Size this 50 mm bore against its neighbors: a 40 mm bore gives 628 N push at 0.5 MPa, while a 63 mm bore provides 1559 N. This SAUF50X75S-08A yields 982 N push at 0.5 MPa. Confirm the AC220V terminal entry coil suits your supply. The rod retracts when energised but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 75 mm stroke, side-load guides are minimal, but ensure alignment for smooth cushioning.
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 SAUF50X75S-08A FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) with an AC220V terminal entry coil. Size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when the coil is energised. You can reconfigure it to extend on signal by repositioning the built-in valve. This self-switching design means no remote valve is needed.
