Airtac SAIF Series Standard Cylinder with Valve SAIF40X450-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X450-06B 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 SAIF40X450-06B
The AirTAC SAIF40X450-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve. Delivering a Cv of 0.78 (14.0 mm2 orifice), this decentralized unit switches itself from a single DC24V terminal electrical connection, eliminating remote plumbing. The assembly operates within a practical 0.15-0.8 MPa range, as the integrated valve limits the cylinder's 1.0 MPa base rating.
Driven by a 3.0 W DC coil with IP65 protection and a 0.05 s response time, the factory setting retracts the piston rod when energised. You can reconfigure it to extend-when-energised by repositioning the valve. The manifold links the valve to the cylinder using O8 x O5 PU tubing, and the 1/8 valve port is distinct from the cylinder's 1/4 port. At 0.5 MPa, it generates 628N of push force.

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 SAIF40X450-06B Is Used
Decentralized Stations
Ideal for large machines where running valve tubing is costly, this self-switching cylinder handles local actuation from a single DC24V signal.
Space-Tight Machines
By integrating the 4M210 valve directly on the profile barrel, it saves valuable panel space and reduces overall plumbing complexity.
Retrofit Upgrades
A drop-in ISO 15552 interchangeable solution for upgrading older lines to decentralized control without adding remote valve islands.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X450-06B the Right Choice?
Choose this 40mm bore if your application requires around 628N push force at 0.5 MPa; stepping down to a 32mm bore yields 402N, while a 50mm bore provides 982N. A self-valved SAIF beats a separate cylinder plus remote valve in space-tight machines by cutting tubing runs and panel footprint. Because the 450mm stroke exceeds 300mm, add a guide to manage side loads and prevent rod binding.
For replacements, match the 40mm bore, 450mm stroke, 1/8 valve port, DC24V voltage, terminal entry, and PT thread. Note that the 5/2 valve routes air but does not lock the load without live pressure; for position holding, consider an AirTAC SAIL lock cylinder.
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 SAIF40X450-06B FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78).
No, it switches itself from one DC24V coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
