Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-06B is a genuine double-acting profile-type cylinder with a Ø40mm 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 SAUF40X200-06B
The SAUF40X200-06B 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 is shorter than an ISO 15552 unit of the same bore. This 40mm bore uses a 1/4" cylinder port, a 1/8" valve port, and a 21mm adjustable cushion.
Operating pressure is 0.15-0.8 MPa, governed by the integrated valve rather than the 1.0 MPa cylinder body. At 0.5 MPa it delivers 628N push and 528N pull. The 4M210-06 valve provides 14 mm2 flow (Cv 0.78) at up to 5 cycles per second. For sizing, the safe working load is roughly 377N, and it can vertically lift about 32kg with a 2:1 margin. This terminal-entry, PT-thread model has no 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X200-06B Is Used
Diverter Gate
Decentralized conveyor sorting where the integrated valve switches the gate directly without a remote manifold.
Clamp Station
Independent machining clamp actuated by a single DC24V signal, saving manifold space on a large cell.
Package Stopper
Inline packaging stopper that cycles at up to 5 Hz, using local 1/8" valve ports to cut tubing runs.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200-06B the Right Choice?
Size force within the 0.15-0.8 MPa valve window. At 0.5 MPa this 40mm bore pushes 628N; if you need less, drop to the 32mm bore (402N), or step up to the 50mm bore (982N) for more power. Confirm the DC24V terminal entry and PT threads match your supply. The rod retracts when the coil is energised, but you can reposition the valve to extend on energisation. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 200mm stroke, guide the mechanism to manage side loads.
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 SAUF40X200-06B FAQ
It pushes 628N and pulls 528N 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. Size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
No. The 5/2 valve only routes air; it is not a lock. If air is lost, the piston drifts and the 21mm cushion only decelerates near stroke end. Install an external rod lock or pilot-operated check valve for load holding.
