Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 200mm 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 SAUF50X200S-06B
The AirTAC SAUF50X200S-06B is a double-acting profile cylinder with a built-in 4M210-06 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. This 50mm bore unit has a 1/4" cylinder port, an M16x1.5 rod thread, and a 200mm stroke.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push and 825N pull at 0.5 MPa. The safe working load is approximately 589N (60% of the 0.5MPa push force), capable of a 50kg vertical lift with a 2:1 margin. The integrated valve provides 14mm2 flow (Cv 0.78) at 1/8" port, cycling up to 5 times per second. The DC24V coil offers IP65 protection with terminal entry. The -S suffix indicates a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF50X200S-06B Is Used
Diverter Gate Actuation
Decentralized sorting on conveyor lines where one coil signal per gate eliminates long tubing runs back to a central manifold.
Package Push-off Station
Independent pallet pushers using local 4M210-06 valves, freeing up manifold slots and reducing installation time on large packaging machines.
Modular Fixture Clamping
Self-switching clamps on machining cells where the built-in magnet allows direct position feedback via CMSG switches.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200S-06B the Right Choice?
Size by comparing neighboring bores: the 40mm bore yields 628N push at 0.5 MPa, while the 63mm bore provides 1559N. This 50mm bore gives 982N push and 825N pull at 0.5 MPa. Confirm the DC24V coil and terminal entry match your supply. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa operating range. Default action retracts the rod when energized; reposition the valve to extend on energization. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For this 200mm stroke, ensure adequate side-load guidance.
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 SAUF50X200S-06B FAQ
It generates 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) with a DC24V coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend when energized simply by repositioning the valve on the cap. This self-switching design removes the need for a separate remote valve.
