Airtac SAIF Series Standard Cylinder with Valve SAIF40X175-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X175-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 175mm 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 SAIF Series Standard Cylinder with Valve SAIF40X175-06B
The AirTAC SAIF40X175-06B is a double-acting profile cylinder with an integrated 4M210-06 5/2 solenoid valve, delivering a 14.0 mm2 effective area (Cv 0.78) and a maximum cycle frequency of 5 cycles per second. Driven by a DC24V terminal coil consuming 3.0 W, it features an IP65 rated electrical connection and a rapid activation time of 0.05 seconds or less. The assembly operates within a practical pressure range of 0.15-0.8 MPa, as the built-in valve limits the cylinder's 1.0 MPa rating, while the carbon steel piston rod handles a push force of 628N and a pull force of 528N at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via PU tubing (O8 x O5), and it is crucial to note the valve port is 1/8 inch (code 06) while the cylinder port is 1/4 inch. This self-switching design eliminates the need for remote plumbing, saving panel space and making it ideal for decentralized installations across large machines.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø40mm)

|---|---|---|
| 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.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF40X175-06B Is Used
Decentralized Machine Stations
Eliminates long air tubes from a central manifold; each station controls itself locally via the DC24V signal.
Compact Assembly Automation
Saves panel and floor space by mounting the 5/2 valve directly to the cylinder profile, ideal for tight cells.
Retrofit & Upgrade Projects
Replaces standalone cylinders where running new valve tubing is costly, using the existing 24V DC control logic.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X175-06B the Right Choice?
Choose this 40mm bore when a 32mm bore (402N push at 0.5 MPa) lacks thrust, but a 50mm bore (982N push at 0.5 MPa) is physically oversized for your envelope. A self-valved SAIF40X175-06B beats a separate cylinder plus remote valve in space-constrained machines by consolidating control and actuation into one unit, driven directly by a DC24V terminal signal. Ensure your replacement matches the 175mm stroke, 1/4 inch cylinder port, 1/8 inch valve port, DC24V voltage, terminal entry, PT tapered threads, and standard carbon steel rod without a magnet. Since the 175mm stroke is under the 300mm threshold, standard mountings handle the load without auxiliary side-load guides.
Remember that the integrated 5/2 valve routes air but does not lock the load; without live pressure, the cylinder will not hold position. For applications requiring true mechanical load holding, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder series instead.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF40X175-06B FAQ
At 0.5 MPa operating pressure, this 40mm bore cylinder provides a push force of 628N and a pull force of 528N. The maximum thrust is 128 kgf at 1.0 MPa, but the practical working range is 0.15-0.8 MPa due to the built-in valve.
No, the integrated 4M210-06 5/2 valve controls the cylinder directly from a single DC24V terminal coil signal. By factory default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
