Airtac SAIF Series Standard Cylinder with Valve SAIF32X125-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X125-08B 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 SAIF32X125-08B
The AirTAC SAIF32X125-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve. Delivering a Cv of 0.89, it operates on DC24V via a terminal connection drawing 3.0 W. The integrated manifold uses an O8xO5 PU tube to bridge the valve and cylinder, eliminating the need for remote plumbing. While the cylinder body rates to 1.0 MPa, the valved assembly operates at 0.15-0.8 MPa.
Generating 402N of push force at 0.5 MPa, this 32mm bore unit is designed for decentralized stations. Factory-set to retract when energised, the valve can be repositioned to extend on signal. It holds position pneumatically via pilot pressure, not mechanically; for true load holding, consider the SAIL lock series.

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 SAIF32X125-08B Is Used
Decentralized Stations
Ideal for large machines where running individual valve lines is costly, driving 402N push force from a single DC24V terminal signal.
Compact Assembly
Fits space-tight machinery by integrating the 4M210-08 valve directly on the profile barrel, saving valuable panel footprint.
Retrofit Automation
Upgrades existing ISO 15552 mounts by adding self-switching 5/2 logic without requiring external pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X125-08B the Right Choice?
Choose this self-valved SAIF32X125-08B when panel space is tight and running separate valve tubing is costly; it switches directly from one DC24V coil signal. If your application requires more thrust, stepping up to the 40mm bore yields 628N push at 0.5 MPa. Conversely, if you need less force, the 32mm is the smallest available SAIF option.
When ordering a replacement, verify the 125mm stroke, 1/4" valve port, DC24V terminal coil, PT thread, and standard carbon steel rod. Because this unit lacks a magnet, it cannot host CMSE reed or DMSE electronic sensors without modification.
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 SAIF32X125-08B FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a max frequency of 5 cycles per second.
By default, the factory setting retracts the rod when the DC24V coil is energised. You can reconfigure it to extend-when-energised by simply repositioning the valve on the manifold block.
