Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 160mm 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 SAUF50X160S-08B
The SAUF50X160S-08B is a double-acting profile 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 is shorter than an ISO 15552 unit of the same bore. The bore sets the 1/4" cylinder port and M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push at 0.5 MPa. The computed safe working load is 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. The valve flows 16 mm2 (Cv 0.89) at up to 5 cycles/s. This DC24V terminal-entry coil is IP65 rated. The S suffix provides a 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 (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 SAUF50X160S-08B Is Used
Decentralized Clamping
Ideal for clamping stations where mounting a separate valve manifold is impractical, using the built-in valve for direct actuation.
Inline Diverter Gates
Drives sorting flaps on conveyors with one coil signal, cutting tubing runs and simplifying maintenance along the line.
Independent Lift Stations
Powers small vertical lifts in storage systems, offering self-contained operation without a central valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08B the Right Choice?
Size force between the 40 mm bore (628 N push) and 63 mm bore (1559 N push) alternatives, sizing within the 0.15-0.8 MPa valve range rather than the 1.0 MPa cylinder body rating. The computed safe load is 589 N. Confirm the DC24V terminal entry and PT threads. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 160 mm stroke side-load is minimal, but for strokes over 300 mm add a guide.
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 SAUF50X160S-08B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s) with a DC24V terminal-entry coil. The cylinder body rates to 1.0 MPa, but the assembled unit operates at 0.15-0.8 MPa. The bore has a 1/4" cylinder port.
Yes. The default action retracts the rod on energisation, but you can reconfigure it to extend-when-energised by repositioning the built-in valve. This allows flexible machine sequencing without altering the wiring.
