Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 75mm 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 SAUF40X75-08A
The SAUF40X75-08A 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 is shorter than an ISO 15552 unit of the same bore.
It delivers 628 N push and 528 N pull at 0.5 MPa. The integrated valve limits the assembled working pressure to 0.15-0.8 MPa, even though the cylinder body rates to 1.0 MPa. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) with a 5 cycle/s limit. Based on the 0.5 MPa push force, the safe working load is roughly 377 N, and the vertical lift capacity is about 32 kg 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 SAUF40X75-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently, saving manifold space.
Inline Diverter Gate
Perfect for a conveyor diverter that needs a self-contained actuator without running long tubing back to a central valve island.
Independent Pick-and-Place
Suits a compact assembly module where the built-in 4M210 valve allows rapid local switching without extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-08A the Right Choice?
When sizing, compare this 40 mm bore against the neighbouring 32 mm and 50 mm options. The 32 mm bore yields 402 N push, while the 50 mm bore provides 982 N at 0.5 MPa. This 40 mm model provides 628 N push. Confirm the AC220V terminal entry and PT thread suit your control panel. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Size all force within the 0.15-0.8 MPa valve window. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 75 mm stroke, side-load guides are not strictly required, but ensure alignment to prevent binding.
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 SAUF40X75-08A FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-08 5/2 solenoid with a 1/4" port, Cv 0.89, and a 5 cycle/s limit. The coil is AC220V with terminal entry. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design means no remote valve is needed.
