Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-06B 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 SAUF50X200-06B
The SAUF50X200-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 makes it shorter than a standard ISO 15552 unit of the same bore. It features a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating strictly within the valve's 0.15-0.8 MPa range, this 50mm bore delivers 982N push and 825N pull at 0.5 MPa. The integrated valve provides 1/8" porting with a 14mm2 flow (Cv 0.78) and handles up to 5 cycles per second. For sizing, the safe working load is roughly 589N, and it can vertically lift about 50kg with a 2:1 margin. Note this SKU lacks a magnet and cannot accept a sensor.

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 SAUF50X200-06B Is Used
Divert Gate Actuation
Decentralized conveyor sorting where the integrated valve mounts directly at the divert gate, cutting tubing runs to a central manifold.
Independent Clamp Stations
Multi-station machining fixtures needing individual clamp control from a single DC24V signal per actuator without complex valve islands.
Compact Ejection Pusher
Parts ejection in tight machine cells where the shorter profile barrel and cap-mounted valve minimize the overall footprint.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-06B the Right Choice?
Size force between the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. At 0.5 MPa this 50mm bore pushes 982N; if you need less force, step down to the 40mm bore (628N push), or step up to the 63mm bore (1559N push) for heavier loads. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil energises, but you can reposition the valve to extend-when-energised. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. 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 SAUF50X200-06B FAQ
It pushes 982N and pulls 825N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) running on DC24V. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
No. The built-in valve routes air but does not lock the piston. If air drops, the load drifts. For vertical holding you must add an external rod lock or pilot-operated check valve. Also, without the -S suffix, this specific SKU lacks a magnet and cannot mount position sensors.
