Airtac SAIF Series Standard Cylinder with Valve SAIF32X175-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X175-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 175mm 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 SAIF32X175-08B
The AirTAC SAIF32X175-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal coil consuming 3.0 W, it delivers a 0.89 Cv flow. The manifold connects to the cylinder via PU tubing (O8 x O5), meaning the valve port (1/4) is distinct from the cylinder port (1/8). Although the cylinder body rates to 1.0 MPa, the internal pilot valve operates at 0.15-0.8 MPa, setting the practical working pressure for the assembly.
Providing 402N of push force at 0.5 MPa, this 32mm bore unit is designed for decentralized machine stations. By switching itself from a single coil signal, it eliminates remote plumbing and saves panel space. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. Note that the 5/2 valve routes air and does not lock the load; use SAIL for holding requirements.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF32X175-08B Is Used
Decentralized Stations
Ideal for large machines where running individual valve tubing back to a central manifold is impractical, allowing local control from a single DC24V signal.
Compact Assembly Lines
The integrated 4M210 valve on a 32mm ISO 15552 profile saves valuable space in dense assembly cells without sacrificing the 402N push force.
Retrofit Automation
Perfect for upgrading older pneumatic setups where adding a separate valve island is too costly, using the built-in 5/2 valve to control the 175mm stroke locally.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X175-08B the Right Choice?
Choose this 32mm bore SAIF when a compact, self-switching actuator is required for a 175mm stroke; if your application needs greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. The DC24V terminal entry suits standard PLC outputs, and the PT-threaded ports match typical pneumatic fittings. Because the stroke is 175mm, ensure adequate guidance to prevent side-load wear on the rod seals.
A self-valved SAIF excels over a separate cylinder and remote valve when wiring and tubing long distances is costly. To replace this unit, match the 32mm bore, 175mm stroke, 1/4 valve port, DC24V voltage, terminal entry, PT threads, and no magnet (-S omitted). For position feedback, add an -S magnet to use CMSE reed or DMSE electronic sensors.
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 SAIF32X175-08B FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum thrust at 1.0 MPa is 82 kgf, though the practical operating pressure is limited to 0.15-0.8 MPa by the built-in valve.
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the 4M210-08 5/2 valve on the manifold to extend-when-energised. This decentralized design eliminates the need for a separate remote valve.
