Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 200mm stroke and a built-in 4M210-08 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 SAUF50X200-08B
The AirTAC SAUF50X200-08B is a double-acting profile cylinder with a built-in 4M210-08 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 is shorter than an ISO 15552 cylinder of the same bore. This 50mm bore uses a 1/4" cylinder port, a Ø20mm rod with an M16x1.5 thread, and 21mm adjustable cushions.
Size force strictly within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it delivers 982N push and 825N pull. A practical computed insight: safe working load is roughly 589N (about 60% of the 0.5MPa push force), and it can vertically lift around 50kg with a 2:1 margin. The 4M210-08 valve has a 1/4" port, Cv 0.89 flow, and 5 cycles/sec max. It uses terminal entry, PT threads, and Ø8xØ5 PU tube.

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 SAUF50X200-08B Is Used
Decentralized Clamping Stations
Ideal for large machines with multiple clamping points, using one coil signal per actuator to eliminate long tubing runs from a central manifold.
Independent Divert Gates
Mounts directly on conveyor diverters. The integrated 4M210 valve switches the 50mm bore locally at up to 5 cycles/sec without needing a remote valve island.
Localized Package Stops
Perfect for distribution lines where each stopper needs autonomous control. The compact profile saves space while delivering 982N push force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200-08B the Right Choice?
When sizing, compare neighboring bores: a 40mm bore gives 628N push while a 63mm bore gives 1559N at 0.5 MPa. This 50mm bore provides 982N push and 825N pull at 0.5 MPa. Confirm the DC24V terminal entry coil meets your supply; allowable DC variance is ±10%. The rod retracts by default when energized, but you can reconfigure it to extend-when-energised by repositioning the valve. Because the 200mm stroke is under 300mm, side-load guides are less critical, but always align the load. The built-in valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for holding. Note this SKU lacks the -S magnet and cannot take a magnetic switch.
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 SAUF50X200-08B FAQ
It generates 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) driven by a DC24V terminal entry coil. Although the cylinder body rates to 1.0 MPa, you must size force within the 0.15-0.8 MPa assembled valve window.
No. The built-in 5/2 valve routes air but does not function as a load lock. If air is lost, the piston drifts and the 21mm cushions only decelerate near stroke end. For vertical load holding, install an external rod lock or pilot-operated check valve.
