Airtac SAIF Series Standard Cylinder with Valve SAIF40X125-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X125-06B 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 SAIF40X125-06B
The AirTAC SAIF40X125-06B is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers 628N of push force at 0.5 MPa. The integrated valve provides a Cv of 0.78 with a 14.0mm2 orifice, operating at a max frequency of 5 cycles per second. The cylinder itself is dimensionally interchangeable per ISO 15552, featuring a carbon steel piston rod and a 1/8 cylinder port.
Because the built-in valve operates from 0.15 to 0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 MPa rather than the bare cylinder's 1.0 MPa limit. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold uses O8xO5 PU tubing, meaning the valve port differs from the cylinder port, and it eliminates the need for a separate remote valve, saving panel space in decentralized machine stations.

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.

| 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 SAIF40X125-06B Is Used
Decentralized Stations
Eliminates the need for long air lines back to a central valve manifold, driving localized control directly at the machine station.
Retrofit Automation
Ideal for upgrading existing machinery where running new valve tubing is costly or physically constrained by the machine frame.
Compact Actuation
Fits into tight machine envelopes by combining the cylinder and 5/2 valve into one assembly, reducing overall footprint.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X125-06B the Right Choice?
Choose this self-valved SAIF40 unit when decentralized stations require compact plumbing without remote valve banks. If you need more thrust, stepping up to the 50mm bore yields 982N push force at 0.5 MPa; if less force is acceptable, the 32mm bore provides 402N. The DC24V terminal coil offers solid-state switching with an IP65 rating and a 0.05s response time. Remember that the 5/2 valve routes air and does not lock the load; for position holding, consider the SAIL series. When ordering a replacement, verify the 125mm stroke, 1/8 cylinder port, 4M210-06 valve port, DC24V voltage, terminal entry, PT threads, and the absence of a 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 SAIF40X125-06B FAQ
At 0.5 MPa, the 40mm bore provides 628N push force and 528N pull force. The integrated 4M210-06 valve has an effective area of 14.0mm2 (Cv 0.78) and supports up to 5 cycles per second.
No separate valve is needed. The unit uses a 5/2 internal-piloted solenoid valve that switches the cylinder from one coil signal. The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
