Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-06A 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 SAUF40X150-06A
The AirTAC SAUF40X150-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 1/4" cylinder port, an M12x1.25 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa range, this 40mm bore delivers 628N push and 528N pull at 0.5 MPa. The integrated valve provides 1/8" porting, 14 mm2 flow (Cv 0.78), and handles up to 5 cycles per second. The AC220V terminal-entry coil is IP65 rated. For sizing, the safe working load is roughly 377N, and it can vertically lift about 32kg with a 2:1 margin.

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 SAUF40X150-06A Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running individual lines to a central manifold is impractical, switching directly from one AC220V signal.
Inline Diverting
Mounts directly on conveyor frames for package diverting, saving tubing and manifold space while delivering 628N push force at 0.5 MPa.
Independent Pick-and-Place
Perfect for standalone pick-and-place units where each actuator self-switches, eliminating the need for a remote valve island on the machine.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-06A the Right Choice?
Size this model against its neighbours: a 32mm bore offers 402N push at 0.5MPa, while a 50mm bore provides 982N. This 40mm bore yields 628N push and 528N pull at 0.5MPa. Confirm the AC220V terminal entry and PT threads suit your supply. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. 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. Note that this SKU lacks a magnet and cannot accept a sensor.
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 SAUF40X150-06A FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
Yes, the default action retracts the rod on energisation, but you can reposition the valve to make it extend instead. The valve only routes air; it is not a lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
