Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 150mm 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 SAUF40X150S-06A
The SAUF40X150S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 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 makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" cylinder port, an M12x1.25 rod thread, and a 21mm adjustable cushion.
Operating within the valve's 0.15-0.8 MPa range, this bore pushes 628N and pulls 528N at 0.5 MPa. The integrated 4M210-06 valve has a 1/8" port, 14mm2 flow (Cv 0.78), and cycles up to 5 times per second. The AC220V terminal coil is IP65 rated. For sizing, a safe working load is roughly 377N (60% of the 0.5MPa push), allowing a 32kg vertical lift with a 2:1 margin. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF40X150S-06A Is Used
Decentralized Clamping
Ideal for independent clamping stations on a large machining line, using one coil signal per actuator to save manifold space.
Inline Diverting
Mounts directly on conveyor frames for localized diverting gates, cutting tubing runs back to a central control panel.
Independent Stop Gates
Powers individual package stoppers in high-throughput logistics, switching itself via the built-in 4M210 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-06A the Right Choice?
Size by checking both neighbouring bores: the 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. This 40mm bore provides 628N push and 528N pull at 0.5MPa. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT threads meet your supply. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 150mm stroke, ensure side-load guidance to prevent uneven wear.
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 SAUF40X150S-06A FAQ
It delivers 628N push and 528N pull at 0.5MPa, reaching 1005N push at 0.8MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V terminal coil. The assembled unit must operate within the 0.15-0.8 MPa valve range, despite the 1.0 MPa cylinder body rating.
No, the built-in valve routes air and is not a load lock. The rod drifts on air loss, and the 21mm cushion only decelerates near stroke end. For load holding, install an external rod lock or pilot-operated check valve. Also, the default retract-when-energised action can be reversed by repositioning the valve.
