Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-06B 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 SAUF50X450-06B
The SAUF50X450-06B 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 makes it shorter than an ISO 15552 cylinder of the same bore. It uses a 1/4" cylinder port and an M16x1.5 rod thread.
This 50mm bore model pushes 982N and pulls 825N at 0.5MPa. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. It runs on DC24V via terminal entry. Because the valve limits pressure to 0.15-0.8MPa, size forces within that window. Computed buyer insight: safe working load is ~589N (60% of the 0.5MPa push), allowing a ~50kg vertical lift with a 2:1 margin.

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 SAUF50X450-06B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. The integrated valve removes long tube runs back to a central manifold, speeding up packaging lines.
Independent Machine Station
Ideal for standalone robotic cells where one coil signal per actuator simplifies wiring and avoids dedicating a manifold slot to a single motion.
Vertical Package Stop
Provides a compact 450mm stroke for sorting height variations. The built-in 4M210 valve ensures rapid local response without remote plumbing delays.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-06B the Right Choice?
Size by comparing the 50mm bore (982N push @0.5MPa) against the 40mm (628N) and 63mm (1559N) neighbors. Confirm the DC24V coil and terminal entry suit your control system. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. The cylinder body rates to 1.0MPa, but the assembled SAUF must operate within the 0.15-0.8MPa valve window. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold loads. For the 450mm stroke, use external guides to prevent rod bending and side-load damage.
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 SAUF50X450-06B FAQ
It delivers 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. The valve only routes air and is not a load lock; the piston will drift on air loss, so install an external rod lock or pilot-operated check valve for holding.
