Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08C is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 50mm 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 SAIF32X50S-08C
The AirTAC SAIF32X50S-08C is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a 0.89 Cv flow rate. Driven by an AC110V terminal coil drawing 3.5 VA, it eliminates the need for a remote valve island. The integrated valve operates at 0.15-0.8 MPa, which sets the practical working range for the assembly even though the bare cylinder rates to 1.0 MPa. In the 32mm bore class, it generates 402N of push force at 0.5 MPa.
Factory configured to retract the rod when energised, the valve can be repositioned to extend on signal. The manifold connects to the cylinder via O8xO5 PU tubing, and this -S variant includes a magnet for CMSE reed and DMSE electronic sensors. Because the valve switches the cylinder directly from one coil signal, it drastically reduces plumbing and panel space for decentralized machine stations.

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 SAIF32X50S-08C Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing by switching locally via the AC110V coil, saving panel space across large multi-station machines.
Compact Sorting Diverters
Provides 402N push force at 0.5 MPa with a 0.89 Cv flow, offering rapid 5 cycle/sec actuation for light package routing.
Retrofit Automation Upgrades
Drops into existing ISO 15552 mounting dimensions while bringing integrated valve control to older pneumatic lines without major rework.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08C the Right Choice?
Choose this 32mm bore when 402N of thrust at 0.5 MPa is sufficient; step up to the 40mm bore if your application requires 628N. The self-valved SAIF design is ideal for space-tight machines where running separate valve tubing is costly, as it consolidates actuation and control into one unit. This specific SKU uses an AC110V terminal entry coil with PT tapered threads.
The built-in 5/2 valve routes air and is not a mechanical lock, so it will not hold a load without live pressure. For position holding, consider the SAIL lock variant. When ordering a replacement, verify the 50mm stroke, 1/8 cylinder port, 1/4 valve port, AC110V voltage, terminal entry, PT threads, and the -S magnet requirement.
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 SAIF32X50S-08C FAQ
At 0.5 MPa, the 32mm bore generates 402N of push force and 345N of pull force. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a 0.89 Cv flow rate.
The factory setting retracts the rod when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. No separate remote valve is needed.
