Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-06B 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 SAUF50X500-06B
The SAUF50X500-06B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One DC24V 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. This SKU has no magnet, so it cannot take a magnetic switch.
The 50mm bore delivers 982N push and 825N pull at 0.5MPa. Size within the 0.15-0.8MPa valve window, as the integrated valve limits the assembly below the 1.0MPa cylinder body rating. The 1/8" valve port gives 14mm2 flow (Cv 0.78) at up to 5 cycles/sec. 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 SAUF50X500-06B Is Used
Sorting Diverter
Decentralized diverter gate on a conveyor. The integrated 4M210 valve switches the 500mm stroke directly, removing long tube runs back to a central manifold.
Packaging Pusher
Carton pusher on a packaging line. One DC24V signal extends the 50mm bore actuator, saving manifold space while providing 982N push force at 0.5MPa.
Machine Guard Gate
Automated guard door actuation. The compact profile cylinder fits tight machine frames, with the built-in valve ensuring fast local response up to 5 cycles/sec.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-06B the Right Choice?
Select by checking both neighbours: the 40mm bore yields 628N push while the 63mm bore yields 1559N push at 0.5MPa. This 50mm unit offers 982N push. Confirm the DC24V terminal entry and PT thread. The rod retracts when energised; reposition the valve to extend on signal. Because the 500mm stroke risks rod bending, use an external guide to manage side loads. The valve routes air and is not a lock; for load holding on air loss, add 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 SAUF50X500-06B 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, 5/2 solenoid) running on DC24V. Size the force within the 0.15-0.8MPa valve operating window, even though the cylinder body rates to 1.0MPa.
By default the rod retracts when energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. For holding a load during air loss, install an external rod lock or pilot-operated check valve.
