Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 50mm 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 SAUF50X50-06A
The AirTAC SAUF50X50-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve on the cap. One AC220V 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. The 50mm bore uses a 1/4" cylinder port, a Ø20mm rod, and M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push force at 0.5 MPa. A computed buyer insight: safe working load is ~589N (60% of the 0.5MPa push), and vertical lift is ~50kg with a 2:1 margin. The 1/8" valve port yields 14mm2 flow (Cv 0.78) at up to 5 cycles/s. This terminal-entry, PT-thread SKU lacks a magnet, so it cannot accept a magnetic switch.

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 SAUF50X50-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station fires independently from one AC220V signal, avoiding a central valve manifold.
Inline Divert Gate
Perfect for a conveyor divert arm that needs a self-contained actuator; the built-in 4M210 valve minimizes tubing runs along the frame.
Package Stopper
Suits a packaging line stop gate. The compact profile cylinder saves space while delivering 982N push at 0.5 MPa to halt boxes.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-06A the Right Choice?
Size by checking both neighbors: the 40mm bore gives 628N push while the 63mm bore gives 1559N at 0.5 MPa. This 50mm bore yields 982N push and 825N pull at 0.5 MPa. Confirm the AC220V terminal entry matches your supply. The default action retracts the rod when energized; reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 50mm stroke, side-load guides are not critical, but ensure standard mounting uses AirTAC SC-series accessories.
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 SAUF50X50-06A FAQ
It delivers 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) running on an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
The valve routes air but does not lock the piston; add an external rod lock or pilot-operated check valve for load holding. By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal. Also, this no-magnet SKU cannot accept a magnetic switch.
