Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50S-06B 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 SAUF50X50S-06B
The SAUF50X50S-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. The 50mm bore delivers 982N push and 825N pull at 0.5MPa, with a 1/4" cylinder port and an M16x1.5 rod thread. The integrated valve has a 1/8" port, 14mm2 flow (Cv 0.78), and handles up to 5 cycles per second.
This unit uses a DC24V coil with terminal entry, IP65 protection, and a piston magnet for CMSG/DMSG/EMSG switches. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa working window. Based on the 0.5MPa push force, the safe working load is about 589N, and it can vertically lift roughly 50kg 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 SAUF50X50S-06B Is Used
Decentralized Clamping
Ideal for clamping stations where running a dedicated line to a single actuator saves manifold space and tubing.
Inline Diverter Gates
Perfect for routing packages on a conveyor, as the built-in 4M210 valve provides fast 5Hz actuation without remote plumbing.
Independent Lift Stations
Suitable for multi-station lift points where each cylinder switches itself from one coil signal, simplifying machine wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50S-06B the Right Choice?
Size this 50mm bore against the 40mm (628N push) and 63mm (1559N push) neighbors at 0.5MPa. Confirm the DC24V terminal entry and PT threads match your supply. The rod retracts when the coil energises, but you can reposition the valve to extend-when-energised. Always operate within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For strokes over 300mm, use side-load guides.
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 SAUF50X50S-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 max) with a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
By default the rod retracts when the coil energises, but you can reconfigure it to extend-when-energised by repositioning the valve. The valve only routes air; it is not a load lock, so add an external rod lock or pilot-operated check valve if you need to hold a load.
