Airtac SAIF Series Standard Cylinder with Valve SAIF32X350S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X350S-08E is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 350mm 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 SAIF32X350S-08E
The AirTAC SAIF32X350S-08E is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Driven by an AC24V terminal coil, this unit delivers a Cv of 0.89 and eliminates the need for a separate remote valve. The integrated manifold uses O8 x O5 PU tubing to bridge the valve and cylinder, significantly reducing plumbing and panel space. Because the valve operates at 0.15-0.8 MPa, the practical working pressure of the assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa.
Equipped with a magnet for position sensing, this model works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The 32mm bore generates 402N of push force at 0.5 MPa. By default, the factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The valve port is 1/4" while the cylinder port is 1/8", and the assembly supports speeds of 30-800 mm/s.

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 SAIF32X350S-08E Is Used
Decentralized Machine Stations
Ideal for large machines with multiple actuation points, using the built-in valve to switch locally from a single AC24V signal without a central valve bank.
Space-Constrained Clamping
Delivers 402N of push force at 0.5 MPa in tight envelopes where plumbing a separate remote valve and manifold is physically impossible.
Sensor-Ready Automation
The -S magnet enables precise end-of-stroke detection with CMSE reed or DMSE electronic sensors for automated sequencing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X350S-08E the Right Choice?
Choose this self-valved SAIF cylinder when you need decentralized actuation across a large machine without running long valve tubing back to a central manifold. The 32mm bore provides 402N push force at 0.5 MPa; if your application requires more clamping power, stepping up to the 40mm bore yields 628N. For this 350mm stroke, adding an external guide is recommended to prevent excessive side-load on the piston rod. Remember that the 5/2 valve routes air but does not hold the load without live pressure; for true mechanical locking, consider the SAIL series.
When specifying a replacement, verify the 32mm bore, 350mm stroke, 1/4" valve port, AC24V voltage, terminal entry, PT thread, and the -S magnet. The built-in valve eliminates the need for external pneumatic piping between a valve island and the cylinder, saving wiring and space.
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 SAIF32X350S-08E FAQ
The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89). The 32mm bore cylinder generates 402N of push force and 345N of pull force at 0.5 MPa.
No, the 5/2 solenoid valve routes air but does not function as a lock or brake. The cylinder will not hold its load without live pressure. For load-holding applications, consider the AirTAC SAIL lock cylinder series.
