Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08E 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 SAIF32X175S-08E
The AirTAC SAIF32X175S-08E is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve. Delivering a Cv of 0.89 and operating on an AC24V terminal connection at 3.5 VA, it generates 402N of push force at 0.5 MPa. Because the integrated valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the bare cylinder rates to 1.0 MPa. The -S magnet option enables position sensing with CMSE reed and DMSE electronic switches.
By default, the factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold connects the valve to the cylinder using PU tubing (O8 x O5), meaning the 1/4" valve port differs from the cylinder's 1/8" port. This self-switching design eliminates remote plumbing, saving panel space and making it ideal for decentralized stations across large machines.

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 SAIF32X175S-08E Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve bank, allowing independent 5/2 control of multiple small actuators across a large machine layout.
Space-Constrained Automation
The integrated manifold and profile barrel save valuable panel and tubing space in tight equipment frames while delivering 402N of thrust.
Retrofit & Machine Upgrades
Ideal for upgrading existing ISO 15552 installations where running new valve tubing back to a central control panel is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X175S-08E the Right Choice?
Choose this 32mm bore when you need compact thrust up to 402N at 0.5 MPa; step up to the 40mm bore if your application requires 628N of push force. A self-valved SAIF beats a separate cylinder and remote valve when wiring and space are tight, as one AC24V coil signal drives the entire actuator. For stroke lengths of 175mm or more, ensure your mounting accommodates the extended rod and consider external guide rails to prevent side-load wear on the seals.
When ordering a replacement, verify the 32mm bore, 175mm stroke, 1/4" valve port, AC24V voltage, terminal entry, PT thread, and the -S magnet. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock or BSAI clamp-lock cylinder series instead.
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 SAIF32X175S-08E FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
No, it features a built-in 4M210 5/2 valve driven by an AC24V terminal coil. By factory default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
