Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08F is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 50mm 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 SAIF32X50S-08F
The AirTAC SAIF32X50S-08F is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Delivering a 16.0 mm2 flow (Cv 0.89), the manifold uses an O8xO5 PU tube to bridge the 1/4 valve port to the 1/8 cylinder port. Driven by a DC12V terminal entry coil drawing 3.0 W, it activates in 0.05 s or less. The -S option includes a magnet for CMSE reed and DMSE electronic sensors.
Because the built-in valve operates at 0.15-0.8 MPa, this defines the practical working range for the assembled unit, even though the cylinder body rates to 1.0 MPa. Factory set to retract the rod when energised, the valve can be repositioned to extend on signal. This self-contained design eliminates remote plumbing, saving panel space across decentralized machine stations.

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 SAIF32X50S-08F Is Used
Decentralized Stations
Ideal for large machines with multiple nodes, eliminating long air lines by switching directly at the cylinder via a single DC12V signal.
Compact Assembly
Fits neatly into space-tight machinery where a separate remote valve and manifold block would violate the envelope constraints.
Retrofit Upgrades
Simplifies older machine upgrades by removing the need to plumb dedicated pilot lines back to a central control panel.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08F the Right Choice?
Choose this 32mm bore when you need compact thrust up to 402N push at 0.5 MPa; step up to the 40mm bore if your application requires 628N. The SAIF32X50S-08F excels in tight layouts where running separate valve tubing is costly, switching itself from one DC12V coil signal. For position feedback, pair the internal magnet with DMSE solid-state or CMSE reed switches in the sensor grooves. To replace, match the 50mm stroke, 1/4 valve port, PT threads, and terminal entry.
Note that the 5/2 valve routes air and is not a mechanical lock; the air cushion only decelerates near stroke end. If the machine loses pressure, the cylinder will not hold its load. For true position holding, consider the SAIL lock variant 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 SAIF32X50S-08F 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) with a maximum frequency of 5 cycles per second.
No, it has a built-in 4M210 valve actuated by a DC12V terminal coil. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This eliminates the need for remote plumbing.
