Airtac SAIF Series Standard Cylinder with Valve SAIF40X400-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X400-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 400mm 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 SAIF40X400-06A
The AirTAC SAIF40X400-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers 628N of push force at 0.5 MPa. The built-in valve offers a 14.0 mm2 effective area (Cv 0.78) and cycles up to 5 times per second. Because the valve manifold mounts directly using O8xO5 PU tubing, it eliminates remote plumbing and saves panel space for decentralized machine stations.
While the bare cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. The 5/2 valve is internally piloted and, by factory default, the piston rod retracts when the coil is energised; you can reposition the valve to extend-when-energised if your sequence requires it. The cylinder features a PT1/8 port, variable air cushions at both ends, and a standard carbon steel piston rod.

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 SAIF40X400-06A Is Used
Decentralized Stations
Eliminates the need for long air tubing runs back to a central valve island by switching directly at the machine station via the integrated 4M210 valve.
Material Handling
Provides reliable 628N push force for diverting or lifting products on a 400mm stroke, responding in under 0.05 seconds for fast cycling.
Space-Tight Retrofits
Ideal for upgrading older machines where adding a separate remote valve and extensive piping is physically impossible or too costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X400-06A the Right Choice?
Choose this 40mm bore when you need more thrust than a 32mm unit (402N push at 0.5 MPa) but want a smaller footprint than a 50mm bore (982N push at 0.5 MPa). The 400mm stroke is well within the 1200mm standard maximum, but at this length you should ensure adequate side-load guidance to prevent premature seal wear. The integrated 4M210-06 valve with a PT1/8 port and AC220V terminal connection means one signal wire drives the actuator directly at the station, drastically reducing tubing runs compared to a traditional cylinder with a remote valve bank.
This assembly does not hold its load without live air pressure, as the 5/2 valve routes air rather than locking it; for position holding consider a SAIL lock variant. To replace this unit, match the 40mm bore, 400mm stroke, 1/8 valve port, AC220V voltage, terminal entry, PT thread, and standard rod without 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 SAIF40X400-06A FAQ
At 0.5 MPa operating pressure, the 40mm bore provides 628N of push force and 528N of pull force. The integrated 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) to handle the required airflow.
The 5/2 valve is internally piloted and holds its last position via pilot pressure, not a spring. By factory default, energising the AC220V coil retracts the rod, but you can reposition the valve to extend-when-energised.
