Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 150mm 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 SAUF40X150-08A
The SAUF40X150-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 21mm adjustable cushions.
The integrated valve restricts the working pressure to a 0.15-0.8 MPa window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 628N push and 528N pull force. This yields a safe working load of roughly 377N, or a 32kg vertical lift with a 2:1 margin. The AC220V terminal entry coil is IP65 rated, and the 1/4" valve port provides a Cv of 0.89 with a maximum cycle speed of 5 cycles per second. This SKU lacks the S magnet suffix, 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 SAUF40X150-08A Is Used
Decentralized Clamping Station
Ideal for a machining cell where the integrated 4M210 valve switches the clamp locally, saving tubing runs back to a central manifold.
Inline Diverter Gate
Drives a sorting flap directly from one AC220V signal. The compact profile fits tight conveyor frames without extra valve plumbing.
Independent Forming Press
Provides 628N push at 0.5 MPa for a small press operation. The built-in valve simplifies control wiring in standalone machine cells.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-08A the Right Choice?
Size force within the 0.15-0.8 MPa valve range: this 40mm bore gives 628N push at 0.5 MPa. If you need less force, step down to the 32mm bore (402N); for more power, step up to the 50mm bore (982N). Confirm the AC220V terminal entry coil matches your supply. The rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The valve routes air, so it is not a load lock. For a held load without air, add an external rod lock or pilot-operated check valve. At 150mm stroke, side-load is minimal, but always guide the load for longer strokes over 300mm.
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 SAUF40X150-08A FAQ
It pushes 628N and pulls 528N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) driven by an AC220V terminal entry coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve. Because the valve only routes air, it cannot hold a load without air pressure. Add an external rod lock or pilot-operated check valve for load holding.
