Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 75mm 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 SAUF50X75S-06A
The SAUF50X75S-06A is a double-acting profile cylinder with a built-in AirTAC 4M 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 is shorter than an ISO 15552 cylinder of the same bore. This unit includes a piston magnet for CMSG/DMSG/EMSG switches.
It hosts a 4M210-06 valve with a 1/8" port, 14 mm2 flow (Cv 0.78), and 5 cycles/s. The cylinder body rates to 1.0 MPa, but the integrated valve limits operation to 0.15-0.8 MPa. At 0.5 MPa it pushes 982 N and pulls 825 N. The computed safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. The bore sets the 1/4" cylinder port and M16x1.5 rod thread.

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-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently without a central valve manifold.
Inline Diverters
Perfect for conveyor sorting gates that require individual actuation, saving tubing and simplifying installation along the line.
Package Stops
Suits independent package stopping mechanisms in distribution hubs, eliminating the need for remote valve plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-06A the Right Choice?
When sizing, compare this 50 mm bore against the 40 mm and 63 mm neighbors. At 0.5 MPa it delivers 982 N push and 825 N pull. Confirm the AC220V terminal entry and PT threads. The rod retracts by default when energized, but you can reposition the valve to extend on signal. Size all forces within the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder body rating. The valve routes air and does not function as a load lock; add an external rod lock or pilot-operated check valve to hold loads. For this 75 mm stroke, side-load guides are not critical, but always guide longer strokes above 300 mm.
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-06A FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-06 with a 1/8" port, Cv 0.78, and 5 cycles/s max. It uses an AC220V terminal entry coil. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend when energized simply by repositioning the built-in valve. This self-switching design removes the need for a separate remote valve.
