Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-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 SAIF40X175S-06B
The AirTAC SAIF40X175S-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering an effective flow of 14.0 mm2 (Cv 0.78). It is configured with a DC24V terminal entry coil consuming 3.0 W, featuring IP65 protection and a 0.05 s activation time. The integrated manifold connects the valve to the cylinder using an O8 x O5 PU tube, meaning the valve port (1/8) is distinct from the cylinder port (1/4). This assembly operates within a 0.15-0.8 MPa range, as the built-in valve limits the cylinder's 1.0 MPa rating. It delivers 628N of push force at 0.5 MPa.
By switching itself from a single coil signal, this unit eliminates the need for remote plumbing and saves panel space, making it ideal for decentralized stations across large machines. The factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. The included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for position feedback.

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 SAIF40X175S-06B Is Used
Decentralized Machine Stations
Ideal for large assembly lines where running individual valve tubing back to a central manifold is costly, allowing each station to control itself via a single DC24V signal.
Compact Handling Systems
Saves valuable panel and footprint space by integrating the 4M210 valve directly onto the cylinder body, perfect for space-constrained packaging and handling machinery.
Retrofit & Upgrade Projects
Drops into existing ISO 15552 mounting interfaces to upgrade older systems with self-switching capabilities, drastically reducing pneumatic re-plumbing effort.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-06B the Right Choice?
Select this 40mm bore when you need 628N push force at 0.5 MPa, or step down to the 32mm bore for 402N in lighter-duty pick-and-place tasks. A self-valved SAIF beats a separate cylinder and remote valve when wiring and space are tight, as it requires only one DC24V electrical signal to operate. If your machine layout needs load holding, note that the 5/2 valve routes air but does not lock the load; for true position holding, consider the SAIL lock or BSAI clamp-lock variants. For replacement, verify the 175mm stroke, 1/8 valve port, DC24V terminal entry, PT threads, and the -S magnet.
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 SAIF40X175S-06B FAQ
The 40mm bore provides 628N push force and 528N pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
The built-in 5/2 valve allows the cylinder to operate from a single DC24V coil signal without needing a separate remote valve. By factory default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
