Airtac SAIF Series Standard Cylinder with Valve SAIF32X250-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250-06B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm stroke and a built-in 4M210-06 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 SAIF32X250-06B
The AirTAC SAIF32X250-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific configuration uses a DC24V terminal entry coil consuming 3.0W, protected to IP65 with a 0.05s response time. The built-in valve offers an effective area of 14.0 mm2 (Cv 0.78) and operates at 5 cycles per second. By integrating the valve directly onto the manifold block via O8xO5 PU tubing, it eliminates the need for a separate remote valve, saving panel space and simplifying decentralized machine stations.
While the base cylinder rates to 1.0 MPa, the practical working pressure for this valved assembly is 0.15-0.8 MPa. Operating at 0.5 MPa, the 32mm bore yields a push force of 402N and a pull force of 345N. The factory setting retracts the piston rod when the coil is energised, but you can reconfigure the valve to extend-when-energised by simply repositioning it. The cylinder port is PT 1/8, while the valve port code is 06, and these distinct air paths should never be confused during installation.

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 SAIF32X250-06B Is Used
Decentralized Assembly Stations
Perfect for large machines with scattered pneumatic points. The integrated 4M210 valve means you only run a single DC24V signal and main air line to the station, drastically cutting tubing costs.
Space-Constrained Machinery
When panel space is tight, this self-valved cylinder eliminates the need for a remote valve bank. The 32mm profile barrel and manifold block fit neatly into compact automation cells.
Retrofit and Upgrades
Ideal for upgrading older machines where routing new valve tubing is costly. The terminal entry coil makes wiring straightforward, and the ISO 15552 mounting interface ensures dimensional drop-in compatibility.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250-06B the Right Choice?
Choose this 32mm bore when your application requires 402N of push force at 0.5 MPa. If you need more thrust, stepping up to the 40mm bore increases push force to 628N at the same pressure. The SAIF32X250-06B is ideal over a standard SAI cylinder plus remote valve when you want to minimize plumbing and wiring across decentralized stations. It uses a DC24V terminal coil with PT threaded ports. To replace this unit, match the 32mm bore, 250mm stroke, 06 valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. Since the 250mm stroke exceeds 300mm? No, but for any stroke approaching mid-range limits, always ensure proper guide support to prevent excessive side loads on the profile barrel.
Remember that the built-in 5/2 valve routes air but does not lock the load. If your machine requires true position holding without live pressure, consider the SAIL (lock) or BSAI (clamp-lock) series instead. The air cushion only decelerates the piston near the stroke ends.
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 SAIF32X250-06B FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The built-in 4M210-06 valve provides an effective area of 14.0 mm2 (Cv 0.78) with a maximum operating frequency of 5 cycles per second.
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the 5/2 valve on the manifold block. The valve holds its position via internal pilot pressure, not a spring.
