Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08F is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 125mm 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 SAIF32X125S-08F
The AirTAC SAIF32X125S-08F is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by a DC12V terminal entry coil drawing 3.0 W, it integrates switching directly on the actuator. The cylinder body rates to 1.0 MPa, but because the internal piloted valve operates at 0.15-0.8 MPa, the practical working range for the assembled unit is 0.15-0.8 MPa. At 0.5 MPa it yields 402N of push force.
This SKU includes a magnet for CMSE reed and DMSE electronic sensors. The manifold connects to the cylinder via O8xO5 PU tubing, meaning the 1/4 valve port differs from the 1/8 cylinder port. Factory-set to retract when energised, the valve can be repositioned to extend on signal, allowing fully decentralized machine stations without remote plumbing.

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 SAIF32X125S-08F Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines, driving the 402N push motion directly from a local DC12V signal.
Space-Constrained Automation
Fits into tight machine envelopes where separate plumbing and panel space are unavailable, using the built-in 4M210-08 manifold.
Retrofit & Upgrades
Ideal for upgrading existing ISO 15552 cylinders to self-switching units without re-routing long pneumatic lines back to a central controller.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08F the Right Choice?
Choose this 32mm bore when a compact, self-valved actuator is needed; step up to the 40mm bore if your application requires the 628N push force available at 0.5 MPa. The SAIF32X125S-08F excels in space-tight machines where running separate valve tubing is costly, as one DC12V wire drives the unit. The 125mm stroke is standard and under the 1000mm maximum. For position feedback, fit CMSE or DMSE switches into the sensor groove. Remember the 5/2 valve routes air and is not a lock; if the machine loses pressure, the load will not hold. For locking needs, consider the SAIL series. Replacement requires matching bore, 125mm stroke, 1/4 valve port, DC12V terminal coil, PT 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 SAIF32X125S-08F FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The integrated 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
It uses a 5/2 solenoid valve that holds position via internal pilot pressure, not a spring. This specific model uses a DC12V terminal coil (3.0 W, IP65). By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to make it extend-when-energised. No separate remote valve is needed.
