Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08F is a genuine double-acting ISO 15552 cylinder with a Ø32mm 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 SAIF32X450S-08F
The AirTAC SAIF32X450S-08F is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Equipped with a position magnet (-S), it works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The built-in valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and handles up to 5 cycles per second. Driven by a DC12V terminal entry coil drawing 3.0 W, it activates in 0.05 s or less.
Because the 5/2 valve operates at 0.15-0.8 MPa, this defines the practical working range for the assembled unit, even though the bare cylinder rates to 1.0 MPa. The manifold connects to the cylinder via O8 x O5 PU tubing, meaning the 1/4" valve port and the 1/8" cylinder port are distinct. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal. This decentralized design eliminates remote plumbing and panel space.

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 (Ø32mm)

|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAIF32X450S-08F Is Used
Decentralized Stations
Eliminates the need for a remote valve bank, letting a single DC12V signal drive the cylinder directly at the machine station.
Retrofit Automation
Ideal for upgrading existing lines where routing new pneumatic tubing to a central manifold is costly or physically constrained.
Compact Assembly Handling
Provides 402N push force at 0.5 MPa with a built-in 5/2 valve, saving panel space in tight machinery layouts.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08F the Right Choice?
Choose this 32mm bore for lighter duties requiring 402N push force at 0.5 MPa; step up to the 40mm bore if you need 628N. The 450mm stroke is substantial for this size, so ensure adequate guide support to prevent rod side-loading and premature seal wear. The integrated valve switches itself from one DC12V signal, which is ideal for retrofitting decentralized stations where running pneumatic tubing to a remote valve is costly.
This assembly does not hold its load without live air pressure—the 5/2 valve routes air but is not a lock; for clamping or safety holds, consider the SAIL lock variant. When ordering a replacement, confirm the 32mm bore, 450mm stroke, 1/4" valve port, DC12V terminal coil, PT tapered threads, and the -S magnet.
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 SAIF32X450S-08F FAQ
At 0.5 MPa, the 32mm bore generates 402N push and 345N pull force. The integrated 4M210-08 valve has a 16.0 mm2 orifice (Cv 0.89) and supports up to 5 cycles per second.
The 5/2 valve is internal piloted and holds its last position by pilot pressure, not a spring. Factory-set to retract when the DC12V coil is energised, it can be repositioned on the manifold to extend instead.
