Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08C is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm 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 SAIF32X250S-08C
The AirTAC SAIF32X250S-08C is a double-acting ISO 15552 profile cylinder with an integrated 4M210-08 5/2 solenoid valve, providing a Cv of 0.89. It is configured with an AC110V terminal electrical entry and includes a magnet for CMSE reed and DMSE electronic sensors. While the bare cylinder rates to 1.0 MPa, the internal piloted valve operates at 0.15-0.8 MPa, making the practical working range for this assembly 0.15-0.8 MPa. The 32mm bore generates 402N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The manifold uses an O8xO5 PU tube, and the valve port (1/4) differs from the cylinder port (1/8). This self-switching design eliminates remote plumbing, saving panel space for decentralized stations across large machines.

| 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 SAIF32X250S-08C Is Used
Decentralized Stations
Ideal for large machines where running individual valve tubing is costly, utilizing a single AC110V signal to drive localized actuation.
Compact Assembly
Saves valuable panel and floor space by integrating the 4M210 valve directly onto the 32mm profile cylinder, eliminating remote plumbing.
Sensor-Ready Automation
The -S magnet enables precise position detection with AirTAC CMSE reed and DMSE electronic switches along the 250mm stroke.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08C the Right Choice?
Select this 32mm bore when you need compact actuation; stepping up to the 40mm bore raises the 0.5 MPa push force to 628N. The SAIF series excels over a separate cylinder and remote valve by cutting tubing costs and wiring complexity in decentralized layouts. For load-holding applications, note that the 5/2 valve routes air but does not lock the load—consider the SAIL series for pneumatic locking. Because the 250mm stroke exceeds 300mm? No, but at 250mm you should still verify guide tolerance for side loads. To match this unit exactly, specify 32mm bore, 250mm stroke, 1/8 cylinder port, 4M210-08 valve (1/4 port), AC110V, terminal entry, PT thread, 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 SAIF32X250S-08C FAQ
The 32mm bore generates 402N of push force at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
Yes, the SAIF32X250S-08C controls itself from one AC110V coil signal. The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
