Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 175mm 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 SAUF40X175S-08A
The SAUF40X175S-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.
This 40mm bore delivers 628N push and 528N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa window. The integrated valve provides 1/4" porting, 16mm2 flow (Cv 0.89), and 5 cycles/sec. The computed safe working load is roughly 377N, and it can vertically lift about 32kg with a 2:1 margin. It includes a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF40X175S-08A Is Used
Decentralized Clamping
Ideal for independent clamping stations on a large machining line where running individual lines back to a central manifold is impractical.
Inline Diverters
Powers conveyor sorting gates directly at the actuator, using one AC220V coil signal to switch without extra tubing.
Package Pushers
Drives localized package reject arms in logistics hubs, saving manifold space and simplifying installation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-08A the Right Choice?
Size force between the 32mm bore (402N push) and 50mm bore (982N push) alternatives at 0.5MPa. This 40mm bore provides 628N push and 528N pull, sized strictly within the 0.15-0.8MPa valve operating range, not the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry and PT thread. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The integrated valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for hold. For this 175mm stroke, ensure side-load guidance.
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 SAUF40X175S-08A FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-08 (Cv 0.89, 1/4" port) running on AC220V with terminal entry. You must size force within the valve's 0.15-0.8MPa operating window, even though the cylinder body rates to 1.0MPa.
No. The built-in valve only routes air and is not a lock. The rod retracts when energised by default, but can be reconfigured to extend by repositioning the valve. For load holding on air loss, install an external rod lock or pilot-operated check valve.
