Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 450mm 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 SAIF40X450S-06B
The AirTAC SAIF40X450S-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Equipped with a DC24V terminal coil drawing 3.0 W, it achieves an IP65 rating and responds within 0.05 seconds. Because the cylinder body rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The 40mm bore delivers 628N of push force at 0.5 MPa, while the -S magnet enables position tracking via CMSE reed or DMSE electronic sensors.
By default, the factory setting retracts the piston rod when the coil is energised, which can be reconfigured to extend-when-energised by simply repositioning the valve. The manifold links the valve to the cylinder using PU tubing (O8 x O5), and the 1/8" valve port is distinct from the cylinder's PT1/8 port. This self-contained design eliminates remote plumbing, saving panel space and making it ideal for 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.
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 SAIF40X450S-06B Is Used
Decentralized Assembly Lines
Perfect for large machines where running individual valve tubing is costly, allowing each station to switch itself via a single DC24V signal.
Space-Constrained Machinery
The built-in 4M210 valve and manifold block minimize pneumatic footprint, fitting neatly into tight automation cells.
Retrofit Automation
Ideal for upgrading existing ISO 15552 setups where adding a remote valve island is impractical, simplifying electrical control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-06B the Right Choice?
Choose this self-valved SAIF40X450S-06B when you need to consolidate wiring and plumbing across decentralized stations, as the integrated 4M210 valve removes the need for a separate remote valve bank. If your application requires greater thrust, stepping up to the 50mm bore yields 982N of push force at 0.5 MPa; conversely, dropping to the 32mm bore provides 402N. For load-holding applications, note that the 5/2 valve routes air but does not lock the load—consider the SAIL series for pneumatic locking needs.
Since the 450mm stroke exceeds 300mm, ensure adequate guidance to prevent excessive side loads on the piston rod. When ordering a replacement, verify the 40mm bore, 450mm stroke, 06 (1/8") valve port, DC24V terminal coil, PT thread, and the -S magnet option.
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 SAIF40X450S-06B FAQ
The 40mm bore generates 628N of push force and 528N of pull force at 0.5 MPa. The integrated 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
No, the 5/2 valve routes air but does not lock the load without live pressure. It features a DC24V terminal entry, and by default, the rod retracts when energised, though it can be reconfigured to extend by repositioning the valve.
