Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 450mm 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 SAUF50X450S-06A
The SAUF50X450S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 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. The bore sets the cylinder air port to 1/4" with an M16x1.5 rod end, and the valve port is 1/8".
Operating within the 0.15-0.8 MPa valve window, it delivers 982 N push and 825 N pull at 0.5 MPa. The safe working load is roughly 589 N, and vertical lift capacity is about 50 kg with a 2:1 margin. The 4M210-06 valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/s. The AC220V terminal-entry coil is IP65 rated. The S suffix means a piston magnet is present 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 SAUF50X450S-06A Is Used
Diverter Gate Actuation
Decentralized sorting line where the integrated valve switches the 450 mm stroke diverter directly at the gate without a remote manifold.
Vertical Package Lift
Lifts packages up to 50 kg using one coil signal, saving tubing and simplifying installation across multiple independent packaging stations.
Machine Tool Loading
Pushes parts into a machining center; the compact profile and built-in 4M210 valve minimize footprint while providing 982 N of push force.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-06A the Right Choice?
Size force between the 32 mm bore (402 N push) and 63 mm bore (1559 N push) alternatives at 0.5 MPa. This 50 mm bore provides 982 N push, but size strictly within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry fits your control panel. The rod retracts when the coil is energised; reposition the valve to extend on signal. The built-in valve routes air and is not a lock, so add an external rod lock or pilot-operated check valve to hold a load. For the 450 mm stroke, use external guides to prevent rod bending and side loads.
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 SAUF50X450S-06A FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s) with an AC220V terminal-entry coil. Size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve for load holding.
