Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08C 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-08C
The AirTAC SAIF32X450S-08C is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by an AC110V terminal coil consuming 3.5 VA, it delivers a Cv of 0.89 and activates in under 0.05 seconds. The carbon steel piston rod provides standard durability, and the -S magnet enables precise position detection with CMSE reed or DMSE electronic sensors. Although the cylinder body rates to 1.0 MPa, the built-in valve limits the practical operating range to 0.15-0.8 MPa.
This self-contained unit eliminates the need for a remote valve island, drastically reducing plumbing and panel space for decentralized stations. The manifold connects to the cylinder via an O8 x O5 PU tube, distinguishing the 1/4" valve port from the cylinder's 1/8" port. Factory-set to retract the rod when energized, the valve can be repositioned to extend on signal. At 0.5 MPa, it generates 402N of push force and 345N of pull 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 (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-08C Is Used
Decentralized Stations
Perfect for large machines with distributed stations, eliminating long tubing runs back to a central valve manifold.
Compact Assembly
Fits into tight machine footprints where mounting a separate valve and cylinder pair is structurally impossible.
Retrofits & Upgrades
Ideal for upgrading existing pneumatic setups where adding new valve wiring is costly, relying on a single AC110V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08C the Right Choice?
Choose this 32mm bore when your application requires around 402N of push force at 0.5 MPa; stepping up to a 40mm bore increases that output to 628N. The 450mm stroke is well within the 1000mm standard maximum but requires attention to side loads—always use a guide to prevent rod binding over extended travel. The integrated 4M210-08 valve operates at up to 5 cycles per second, making it ideal for high-speed, space-constrained machines where running separate tubing from a central panel is costly or complex.
This assembly does not hold its load without live air pressure, as the 5/2 valve routes air rather than locking it; for true mechanical holding, consider the SAIL lock variant. When ordering a replacement, confirm the 450mm stroke, 1/8" cylinder port, 1/4" valve port, AC110V terminal coil, PT thread type, 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 SAIF32X450S-08C FAQ
At 0.5 MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The integrated 4M210-08 5/2 valve provides an effective flow area of 16.0 mm2 (Cv 0.89).
No, the integrated 4M210 valve switches the cylinder directly from one AC110V coil signal. Factory-set to retract when energized, the valve can be repositioned on the manifold to extend-when-energised, and it holds its last position via internal pilot pressure rather than a spring.
