Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-08B 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-08B
The SAUF50X75S-08B is a double-acting profile-type cylinder with a built-in AirTAC 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. This 50mm bore features a 1/4" air port, an M16x1.5 rod thread, and a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push and 825N pull at 0.5 MPa. The integrated valve provides 16mm2 flow (Cv 0.89) and handles up to 5 cycles per second. For sizing, the safe working load is roughly 589N, and it can vertically lift about 50kg with a 2:1 margin. The DC24V terminal coil is IP65 rated.

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-08B Is Used
Decentralized Clamping
Ideal for large fixtures needing one valve per actuator, using the 4M210-08 valve to drive clamps directly without a central manifold.
Inline Diverting
Provides rapid 5 cycle/sec diverting on conveyors where running separate tubing to a remote valve is impractical.
Packaging Gates
Powers sorting gates in packaging lines, saving installation time and tubing by switching itself from one DC24V signal.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-08B the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 50mm bore pushes 982N at 0.5 MPa, sitting between the 40mm (628N) and 63mm (1559N) options. The 75mm stroke is above the 50mm minimum. Confirm the DC24V terminal entry and PT thread meet your control specs. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For strokes over 300mm, use side-load guides.
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-08B FAQ
It pushes 982N and pulls 825N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) running on a DC24V terminal coil. Size the assembled unit within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod on energisation, but you can reposition the valve to make it extend-when-energised. This flexibility lets you match the fail-safe state of your machine without extra remote valves.
