Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-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 SAUF40X150S-08A
The SAUF40X150S-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 directly, 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 delivers 628 N push and 528 N pull at 0.5 MPa. The integrated valve operates at 0.15-0.8 MPa with a 1/4" port and Cv 0.89, running up to 5 cycles per second. The AC220V terminal entry coil is IP65 rated. A computed buyer insight: safe working load is roughly 377 N, and vertical lift is about 32 kg with a 2:1 margin. The bore's cylinder port is 1/4".

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-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Divert Gate
Perfect for a conveyor diverter that needs a self-contained actuator. The built-in valve minimizes tubing runs along the frame.
Package Stopper
A packaging line stopper that cycles up to 5 times per second, benefiting from the integrated 4M210 valve and fast response.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150S-08A the Right Choice?
Size force within the 0.15-0.8 MPa valve window. If 628 N push at 0.5 MPa is insufficient, step up to the 50 mm bore which provides 982 N; if excessive, drop to the 32 mm bore at 402 N. This 150 mm stroke is above the 50 mm minimum and below the 1200 mm maximum. Confirm the AC220V terminal entry and PT thread. The rod retracts when energised by default but can be reconfigured to extend by repositioning the valve. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 150 mm stroke side-load is minimal, but for strokes over 300 mm add a guide.
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-08A FAQ
It provides 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-08 with a 1/4" port and Cv 0.89. The coil is AC220V with terminal entry. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the built-in valve. This self-switching design eliminates the need for a separate remote valve.
