Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 450mm stroke and a built-in 4M210-08 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-08A
The AirTAC SAIF40X450S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU is configured for AC220V operation via a terminal electrical entry with PT threads, drawing 3.5 VA and responding in 0.05 s. The built-in valve provides a 16.0 mm2 effective orifice (Cv 0.89) and switches up to 5 cycles per second. Because the manifold links the valve to the cylinder using O8 x O5 PU tubing, the 1/4 inch valve port and the cylinder's 1/4 inch port are kept distinct.
While the bare cylinder rates to 1.0 MPa, the practical operating pressure for this self-contained SAIF unit is 0.15-0.8 MPa, yielding a 628 N push force at 0.5 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The -S magnet option supports CMSE reed and DMSE electronic sensors for position feedback. This assembly controls itself from one coil signal, eliminating remote plumbing and saving panel space for decentralized installations.

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 SAIF40X450S-08A Is Used
Decentralized Machine Stations
Ideal for large machines where mounting a remote valve bank is impractical; the built-in 4M210 valve lets each station control itself independently.
Space-Constrained Automation
Perfect for tight retrofits where adding external pneumatic plumbing is impossible, utilizing a single AC220V terminal connection to drive the 40mm bore.
Material Handling Gates
Provides 628N of push force at 0.5 MPa for diverting or gating packages on a conveyor, with the integrated valve ensuring fast 5 cycle/sec switching.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X450S-08A the Right Choice?
Choose this 40 mm bore if your application requires around 628 N of push force at 0.5 MPa; stepping down to a 32 mm bore reduces that to 402 N, while a 50 mm bore increases it to 982 N. The self-valved SAIF design is highly advantageous for decentralized stations where running separate valve tubing is costly or space-prohibitive. For load-holding applications, note that the 5/2 valve routes air and does not lock the load—consider an AirTAC SAIL lock cylinder for positive holding. When ordering replacements, verify the 450 mm stroke, 4M210-08 valve port, AC220V terminal coil, PT threads, and the -S magnet.
At 450 mm stroke, the piston rod is highly susceptible to side loads. Ensure external guide rails are used to prevent binding and premature seal wear, as the integrated air cushion only decelerates the load near the stroke ends.
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-08A FAQ
The 40 mm bore generates 628 N of push force and 528 N of pull force at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89).
No, the SAIF controls itself from one AC220V coil signal. By factory default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
