Airtac SAIF Series Standard Cylinder with Valve SAIF40X400-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X400-06B 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 SAIF40X400-06B
The AirTAC SAIF40X400-06B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This valve provides a 14.0 mm2 effective area (Cv 0.78) and is wired with a DC24V terminal coil consuming 3.0 W. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates safely at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. Delivering 628N of push force at 0.5 MPa, it uses an O8 x O5 PU tube between the manifold and cylinder.
By default, the piston rod retracts when the coil is energised, though you can reconfigure it to extend-when-energised simply by repositioning the valve. This decentralized design switches itself from one coil signal, eliminating remote plumbing and saving panel space across large machines. The standard carbon steel rod and PT tapered ports make it a drop-in ISO 15552 interchangeable upgrade for decentralized 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.
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 SAIF40X400-06B Is Used
Decentralized Automation
Ideal for large factory lines where running remote valve tubing is costly, utilizing the built-in 4M210 valve for localized switching.
Extended Stroke Handling
Handles 400mm stroke tasks with 628N push force, requiring external guides to manage side loads during long-travel movements.
Space-Tight Machinery
Saves valuable panel space by integrating the 5/2 valve directly onto the cylinder body, perfect for compact machine cells.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X400-06B the Right Choice?
Choose this 40mm bore when your application requires roughly 628N push force at 0.5 MPa; step down to a 32mm bore for 402N or up to a 50mm bore for 982N. A self-valved SAIF beats a separate cylinder and remote valve when you need to minimize wiring and tubing in decentralized machine layouts. This specific SKU uses a DC24V terminal electrical entry and a PT 1/8 valve port. Remember the 5/2 valve routes air but does not lock the load—use AirTAC SAIL for pneumatic locking. Because the 400mm stroke exceeds 300mm, add an external guide to prevent side-load damage.
To replace this unit, match the 40mm bore, 400mm stroke, 4M210-06 valve (1/8 port), DC24V voltage, terminal entry, PT thread, and no magnet (-S).
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 SAIF40X400-06B FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
It uses a 5/2 solenoid valve that holds position via internal pilot pressure. This specific model uses a DC24V terminal coil. The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
