Airtac SAIF Series Standard Cylinder with Valve SAIF40X225-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X225-06A 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 SAIF40X225-06A
The AirTAC SAIF40X225-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal entry coil drawing 3.5 VA, it eliminates the need for a remote valve island. The integrated valve provides a 14.0 mm2 effective area (Cv 0.78) and switches at up to 5 cycles per second. Because the 4M210 valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the cylinder body itself rates to 1.0 MPa.
This self-contained design uses an O8 x O5 PU tube to bridge the manifold and cylinder, which features a 1/8 cylinder port distinct from the valve's 1/8 port. Delivering 628 N of push force at 0.5 MPa, it is ideal for decentralized stations. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence 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)

|---|---|---|
| 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 SAIF40X225-06A Is Used
Decentralized Machine Stations
Eliminates long air lines back to a central valve island by switching locally via the integrated 4M210 valve and a single AC220V signal.
Mid-Stroke Diverting
Provides 225 mm of travel to push products between conveyor lanes, using 628 N of thrust at 0.5 MPa to handle moderate package weights.
Compact Assembly Cells
Saves valuable panel space by mounting the 5/2 valve directly on the ISO 15552 profile body, simplifying the pneumatic schematic.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X225-06A the Right Choice?
Choose this 40 mm bore when a 32 mm cylinder (402 N push at 0.5 MPa) lacks thrust, but a 50 mm bore (982 N) is physically excessive. The 225 mm stroke provides ample travel for medium-range actuation. Because the stroke is 225 mm, ensure adequate guiding to prevent side-load wear on the rod seals. The integrated valve means you only need to run a single AC220V electrical signal and the main air supply, drastically reducing tubing and panel space compared to a separate cylinder and remote valve.
This unit does not hold its load without live air pressure, as the 5/2 valve routes air rather than locking it; for position holding, consider an AirTAC SAIL lock cylinder. To replace this exact configuration, match the 40 mm bore, 225 mm stroke, 1/8 valve port, AC220V voltage, terminal electrical entry, and PT thread. Note this standard carbon steel rod version ships without a sensor 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 SAIF40X225-06A FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. The integrated 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) to handle the required airflow.
No, it is a double-acting system driven by a 5/2 solenoid valve that holds position via internal pilot pressure. By factory default, energizing the AC220V coil retracts the rod, but the valve can be repositioned to extend-when-energised.
