Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 500mm 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 SAUF50X500S-06B
The SAUF50X500S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in decentralized setups. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. The bore dictates a 1/4" cylinder port and an M16x1.5 rod thread, while the valve port is 1/8".
Operating on DC24V with terminal entry, the integrated valve delivers a 14 mm2 flow (Cv 0.78) at up to 5 cycles per second. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa working window. At 0.5 MPa it pushes 982 N and pulls 825 N. For sizing, the safe working load is roughly 589 N (about 60% of the 0.5 MPa push force), and it can vertically lift around 50 kg with a 2:1 margin. 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 SAUF50X500S-06B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The built-in 4M210-06 valve eliminates long tube runs back to a central manifold, ensuring rapid 5 cycle/sec actuation.
Independent Pallet Stop
Ideal for a standalone pallet stop in a large warehouse. One DC24V coil signal drives the 500 mm stroke, saving a manifold slot and simplifying installation.
Remote Clamp Station
Serves as a remote clamping actuator on a large machine bed. The compact profile and integrated switching reduce plumbing complexity while providing 982 N of push force.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-06B the Right Choice?
Size by checking both neighboring bores: the 40 mm bore pushes 628 N while the 63 mm bore pushes 1559 N at 0.5 MPa. This 50 mm bore gives 982 N push and 825 N pull at 0.5 MPa, with a maximum push of 1570 N at the 0.8 MPa valve limit. Confirm your coil is DC24V with terminal entry before ordering. The default action retracts the rod when energized, but you can reposition the valve to extend on energization. Because the 500 mm stroke exceeds 300 mm, add external guides to prevent rod bending and side-load wear. The integrated valve routes air but does not lock the piston; for load holding on air loss, install an external rod lock or pilot-operated check valve.
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 SAUF50X500S-06B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (5/2 solenoid) with 1/8" port, 14 mm2 flow (Cv 0.78), and runs on DC24V. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa working window.
No, the built-in valve only routes air and is not a lock. If air is lost, the piston drifts. For load holding, install an external rod lock or pilot-operated check valve. The default action retracts when energized, but you can reposition the valve to extend on energization.
