Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-06A 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-06A
The AirTAC SAIF40X450S-06A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve, delivering a Cv of 0.78. Driven by an AC220V coil with a terminal electrical entry, it consumes 3.5 VA and features an IP65 rating with a rapid 0.05s activation time. Because the manifold links the valve to the cylinder via an O8xO5 PU tube, the 1/8 valve port and the 1/4 cylinder port remain distinct. The integrated design eliminates the need for a separate remote valve, saving panel space and simplifying decentralized installation across large machines.
While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. The 40mm bore generates 628N of push force at 0.5 MPa. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence requires it. This unit includes a magnet for CMSE reed and DMSE electronic sensors, and its carbon steel rod handles standard loads. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL series.

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.

| 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-06A Is Used
Decentralized Assembly Stations
Eliminates long air lines from a central panel by switching locally via the AC220V terminal coil, reducing plumbing complexity on large automated lines.
Space-Constrained Machinery
The integrated 4M210 valve manifold on the ISO 15552 profile body saves valuable footprint in tight equipment layouts.
Retrofitted Material Handling
Ideal for adding self-switching actuation to existing conveyors where routing new valve tubing back to a main control block is cost-prohibitive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-06A the Right Choice?
Choose this self-valved SAIF40 unit when decentralizing machine logic and minimizing tubing runs are higher priorities than centralized panel control. The 40mm bore provides 628N push force at 0.5 MPa; if your application requires less force, dropping to a 32mm bore yields 402N, while stepping up to a 50mm bore offers 982N. The built-in 4M210-06 valve handles up to 5 cycles per second. With a 450mm stroke, ensure you provide adequate guide support to prevent side-loading and premature seal wear. To replace this exact unit, match the 40mm bore, 450mm stroke, 1/8 valve port, AC220V 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-06A FAQ
The 40mm bore generates 628N of push force at 0.5 MPa and 879N at 0.7 MPa. The built-in 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
Yes. By default, the factory setting retracts the piston rod when the AC220V coil is energised. By physically repositioning the 5/2 valve on the manifold, you can reconfigure it to extend-when-energised. This self-contained switching means no separate remote valve is required.
