Airtac SAIF Series Standard Cylinder with Valve SAIF40X225S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X225S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 225mm 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 SAIF40X225S-06A
The AirTAC SAIF40X225S-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Equipped with a -S magnet for CMSE reed and DMSE electronic sensors, it delivers 628N of push force at 0.5MPa. The AC220V terminal coil draws 3.5 VA, responds in 0.05s, and carries an IP65 rating. Because the manifold block routes air directly via O8xO5 PU tubing, you eliminate remote plumbing and save panel space across decentralized stations.
While the cylinder body itself rates to 1.0MPa, the practical operating range for this valved assembly is 0.15-0.8MPa. The valve orifice is 14.0mm2 (Cv 0.78) and supports a max frequency of 5 cycles/sec. By default, the factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if your logic requires it.

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 SAIF40X225S-06A Is Used
Decentralized Machine Stations
Ideal for large automated lines where installing individual remote valves is impractical, letting each station control its own cycle via a single AC220V signal.
Compact Assembly Automation
Fits neatly into tight mechanical envelopes, using the built-in manifold and short PU tubing to minimize external plumbing on compact clamping or pressing units.
Retrofit & Upgrade Kits
Perfect for upgrading existing ISO 15552 interchangeable profile cylinders, adding self-switching capability without redesigning the pneumatic control panel.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X225S-06A the Right Choice?
Choose this 40mm bore when 32mm lacks thrust: the 40mm bore yields 628N push at 0.5MPa, whereas the 32mm only provides 402N. If your application needs even more force, stepping up to the 50mm bore gives 982N at the same pressure. The self-valved SAIF architecture is ideal for space-tight machines or retrofits where running separate valve tubing is costly, as one AC220V terminal signal drives the entire actuator.
When specifying a replacement, match the 225mm stroke, 1/8" cylinder port, 4M210-06 valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet. At 225mm stroke, ensure your mounting arrangement manages side loads to prevent premature seal wear. Remember that the 5/2 valve routes air but does not hold the load without live pressure; for position holding, consider the SAIL lock series.
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 SAIF40X225S-06A FAQ
At 0.5MPa, the 40mm bore provides 628N of push force and 528N of pull force. The integrated 4M210-06 valve has an effective area of 14.0mm2 (Cv 0.78) and a maximum no-load frequency of 5 cycles per second.
It uses a 4M210-06 5/2 solenoid valve. The AC220V terminal coil consumes 3.5 VA, features IP65 protection, and activates in 0.05s or less. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
