Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06F is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 125mm 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 SAIF40X125S-06F
The AirTAC SAIF40X125S-06F is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a push force of 628N at 0.5MPa. It features a 1/4" cylinder port and a 1/8" valve port, connected via an O8xO5 PU tube. Equipped with a DC12V terminal coil drawing 3.0W, it activates in 0.05s. The integrated valve means no remote valve is needed, saving panel space for decentralized stations. The -S magnet works with CMSE reed and DMSE electronic sensors.
While the cylinder body rates to 1.0MPa, the internal pilot valve operates at 0.15-0.8MPa, setting the practical working range. Factory-set to retract when energised, the valve can be repositioned to extend on signal. The carbon steel rod and PT tapered threads ensure durable, leak-free pneumatic performance.

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)
| 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.

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 SAIF40X125S-06F Is Used
Decentralized Machine Stations
Ideal for large machines with many stations, eliminating long tubing runs to a central panel by controlling the cylinder directly from its built-in valve.
Low-Voltage Control Systems
The DC12V terminal coil draws only 3.0W, making it suitable for low-voltage automated equipment and safety-focused control circuits.
Space-Constrained Retrofits
Perfect for upgrading existing machinery where adding external valves is impossible, providing a complete 5/2 switching solution on the cylinder itself.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06F the Right Choice?
Choose this self-valved SAIF40 unit when you need decentralized actuation without running tubing to a remote valve. If your application requires higher force, step up to the 50mm bore (982N push at 0.5MPa); for lighter duties, the 32mm bore offers 402N. This DC12V terminal model suits low-voltage control systems, activating in 0.05s with 3.0W power. The 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock series. Replacement requires matching 40mm bore, 125mm stroke, 1/8" valve port, DC12V, 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 SAIF40X125S-06F FAQ
The 40mm bore provides a push force of 628N and pull force of 528N at 0.5MPa. The built-in 4M210-06 valve has an effective area of 14.0mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the 5/2 valve routes air but does not lock the load; it holds position only via live pressure. Factory-set to retract when the DC12V coil is energised, it can be repositioned to extend-when-energised. This integrated design removes the need for a separate remote valve.
