Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-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 SAIF32X125S-08B
The AirTAC SAIF32X125S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal entry coil drawing just 3.0 W, it delivers a Cv of 0.89 and activates in 0.05 s. The carbon steel piston rod includes a magnet for position sensing with CMSE reed or DMSE electronic switches. While the bare cylinder rates to 1.0 MPa, the built-in valve limits the practical SAIF operating pressure to 0.15-0.8 MPa.
This 32mm bore generates 402N of push force at 0.5 MPa. The manifold connects to the cylinder using O8xO5 PU tubing, meaning the 1/4" valve port differs from the cylinder's 1/8" port. Factory-set to retract when energised, the valve can be repositioned to extend on signal. It eliminates remote plumbing, making it perfect 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)

|---|---|---|
| 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-08B Is Used
Decentralized Stations
Ideal for large machines with multiple stations, eliminating long air tubing runs by switching locally via the integrated valve.
Space-Tight Machines
Perfect for compact assemblies where external valve manifolds cannot fit, driving 402N loads directly from one coil signal.
Retrofit Installations
Simplifies upgrades where adding remote pneumatic plumbing is costly, requiring only a 3.0W DC24V electrical connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X125S-08B the Right Choice?
Choose this 32mm bore for lighter loads up to 402N at 0.5 MPa; step up to the 40mm bore if you need 628N push force. The self-valved SAIF design beats a separate cylinder and remote valve when panel space is tight and running air tubing is costly. The 4M210-08 valve handles up to 5 cycles per second. Remember the 5/2 valve routes air but does not lock the load—use a SAIL lock cylinder for holding requirements.
For replacement, verify the 125mm stroke, 1/8" cylinder port, 1/4" valve port, DC24V voltage, PT thread, and -S magnet. At 125mm stroke, side loads are minimal, but always ensure proper guide alignment to prevent rod binding.
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-08B FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N push and 345N pull force. The built-in 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and supports up to 5 cycles per second.
No, the built-in 4M210 valve switches the cylinder directly from a DC24V terminal coil signal. By factory default, the piston rod retracts when energised, but you can reposition the valve to extend-when-energised without extra parts.
