Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-08A is a genuine double-acting ISO 15552 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 SAIF Series Standard Cylinder with Valve SAIF40X75S-08A
The AirTAC SAIF40X75S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by an AC220V terminal connection coil consuming 3.5 VA, it eliminates the need for a separate remote valve. The assembly operates within a 0.15-0.8 MPa pressure range, as the integrated valve limits the 1.0 MPa cylinder capacity, while delivering 628N of push force at 0.5 MPa.
This self-contained unit uses an O8 x O5 PU tube to bridge the manifold and cylinder, with a PT1/4 cylinder port and a 1/4 inch valve port. Factory set to retract the rod when the coil is energised, the 5/2 valve can be repositioned to extend on signal. The carbon steel rod and -S magnet option enable precise position sensing with CMSE or DMSE switches.

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 SAIF40X75S-08A Is Used
Decentralized Stations
Ideal for large machines where mounting individual valved cylinders reduces panel space and tubing runs.
Compact Assembly Lines
Fits into tight machine envelopes where a separate valve and manifold block would not physically fit.
Retrofit Upgrades
Simplifies machine upgrades by replacing bare cylinders with self-switching units without adding new air lines.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-08A the Right Choice?
Choose this 40mm bore when a 32mm cylinder (402N push at 0.5 MPa) lacks force, but a 50mm bore (982N) is excessive. The SAIF40X75S-08A excels in decentralized stations where running valve tubing is costly, as one AC220V terminal signal directly controls the actuator. For loads requiring position holding without live pressure, select the SAIL lock cylinder instead, as this 5/2 valve routes air and does not brake the load.
To replace this unit, match the 40mm bore, 75mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet. Since the stroke is under 300mm, side-load guide concerns are minimal.
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 SAIF40X75S-08A FAQ
At 0.5 MPa operating pressure, the 40mm bore provides 628N of push force and 528N of pull force. The maximum push force reaches 1130N at 0.9 MPa.
No, the integrated 4M210-08 5/2 valve is internally piloted and switches directly from the AC220V coil signal. It is factory set to retract when energised but can be repositioned to extend when energised.
