Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 400mm 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 SAIF32X400S-08A
The AirTAC SAIF32X400S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve. This integrated manifold design eliminates the need for a remote valve island, saving panel space and simplifying plumbing for decentralized machine stations. Driven by an AC220V terminal entry coil drawing 3.5 VA, it responds in 0.05 s. The valve provides a 16.0 mm2 flow area (Cv 0.89) and switches up to 5 cycles per second.
Because the 5/2 valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the cylinder body itself rates to 1.0 MPa. At 0.5 MPa it delivers 402N of push thrust and 345N of pull thrust. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal. The -S magnet enables position sensing with AirTAC CMSE (reed) and DMSE (electronic) switches.

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 SAIF32X400S-08A Is Used
Decentralized Assembly Stations
Ideal for large machines where running individual valve tubing back to a central panel is costly. The built-in 4M210 valve lets this 32mm cylinder switch itself from a single AC220V signal.
Compact Sorting Diverters
Provides 402N of push force at 0.5 MPa for diverting lightweight packages. The integrated manifold saves valuable space along tight conveyor frames.
Space-Constrained Automation
Fits ISO 15552 mounting dimensions but eliminates the external valve block. The 400mm stroke handles extended reach tasks without needing remote pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08A the Right Choice?
Choose this 32mm bore when you need compact thrust up to 402N (0.5 MPa) with the convenience of a self-contained valve. If your application requires greater force, stepping up to the 40mm bore yields 628N of push force. The 400mm stroke on this model requires careful attention to side loading; always use a guide rail or external bearing to prevent rod binding over the extended travel.
The SAIF32X400S-08A specifies a 4M210-08 valve with a 1/4" valve port, while the cylinder port is 1/8". The manifold connects them via PU tubing (O8 x O5). Remember that the 5/2 valve routes air but does not lock the load mechanically; for position holding without live pressure, consider an AirTAC SAIL lock cylinder. Replacement match: 32mm bore, 400mm stroke, 1/4" valve port, AC220V, terminal entry, PT thread, with 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 SAIF32X400S-08A FAQ
At 0.5 MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The built-in 4M210-08 5/2 valve has an effective flow area of 16.0 mm2 (Cv 0.89).
No, the SAIF32X400S-08A has a built-in 4M210 5/2 solenoid valve mounted directly on the manifold. Driven by an AC220V coil, it switches itself. By default, the rod retracts when energised, but you can reposition the valve to extend on signal.
