Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 300mm 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 SAUF50X300S-06B
The SAUF50X300S-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 is shorter than an ISO 15552 cylinder of the same bore. The 50mm bore uses a 1/4" cylinder port, a Ø20mm rod with an M16x1.5 thread, and 21mm adjustable cushions.
Driven by a DC24V coil (IP65, terminal entry), the integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. Size force within the valve's 0.15-0.8 MPa window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 982 N and pulls 825 N. The computed safe working load is about 589 N, allowing a vertical lift of roughly 50 kg with a 2:1 margin. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG sensors.

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 SAUF50X300S-06B Is Used
Modular Machine Gating
Drive individual machine guard doors directly from the actuator, using the built-in valve to slash tubing runs across a large assembly cell.
Decentralized Diverters
Switch a 300mm sorting flap on a conveyor line with one DC24V signal, bypassing the need for a central valve manifold.
Independent Lift Stations
Elevate 50kg pallet stops at multiple packing zones, letting the integrated 4M210 valve handle local switching without extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-06B the Right Choice?
Size between neighbours: the 40mm bore pushes 628 N and the 63mm pushes 1559 N at 0.5 MPa. This 50mm bore gives 982 N push and 825 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Because the 300mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load wear. The valve routes air and does not lock the load; if air drops, the piston drifts and the cushion only decelerates near stroke end. Add an external rod lock or pilot-operated check valve to hold a load. Operate within the 0.15-0.8 MPa valve range.
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 SAUF50X300S-06B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by a DC24V coil. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window. The cylinder port is 1/4".
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The valve only routes air; it is not a load lock. If air pressure is lost, the piston drifts and the 21mm cushion merely decelerates it near the end of the 300mm stroke. Use an external rod lock or pilot-operated check valve for load holding.
