Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-08B 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-08B
The SAUF40X175S-08B 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 cylinder, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
It features a 40mm bore, 175mm stroke, and a piston magnet for CMSG/DMSG/EMSG switches. The 1/4" valve port delivers a 16 mm2 flow (Cv 0.89) at up to 5 cycles/s. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the 0.15-0.8 MPa valve window. At 0.5 MPa it pushes 628 N and pulls 528 N, yielding a safe working load of about 377 N or a 32 kg vertical lift 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 SAUF40X175S-08B Is Used
Decentralized Clamping Stations
Ideal for multi-station clamping where each actuator switches itself from one DC24V signal, removing long tube runs back to a central manifold.
Independent Divert Gates
Deploy individual diverters along a conveyor. The integrated 4M210 valve provides rapid 5 cycle/s actuation without complex remote plumbing.
Compact Assembly Pick-Place
Fits tight machine cells. The profile barrel saves space while the built-in magnet supports CMSG/DMSG/EMSG switches for position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X175S-08B the Right Choice?
Size by force and neighbors: this 40mm bore pushes 628 N at 0.5 MPa, sitting between the 32mm (402 N) and 50mm (982 N) options. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil energises, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 175mm stroke, side-load is low, but ensure adequate guiding for longer strokes.
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-08B FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa using a 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/s). The coil is DC24V (IP65, 3.0 W). Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within a 0.15-0.8 MPa window.
Yes. The default action retracts the rod on signal, but you can reposition the built-in valve to make it extend when energised. This allows flexible machine logic without needing a separate remote valve.
