Airtac SAIF Series Standard Cylinder with Valve SAIF32X50-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X50-08A 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 SAIF32X50-08A
The AirTAC SAIF32X50-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This valve offers an effective area of 16.0 mm2 (Cv 0.89) and is mounted directly via a manifold block using O8 x O5 PU tubing. Equipped with an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05s or less. Although the cylinder body rates to 1.0 MPa, the integrated valve limits the practical operating pressure to 0.15-0.8 MPa.
Providing 402N of push force at 0.5 MPa, this 32mm bore unit is designed for decentralized machine stations. By switching itself from a single coil signal, it eliminates remote plumbing and saves panel space. Factory set to retract when energised, the valve can be repositioned to extend on signal. Note the valve port is 1/4 while the cylinder port is 1/8.

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 SAIF32X50-08A Is Used
Decentralized Stations
Ideal for large machines where running individual valve lines is costly, letting each cylinder control itself locally.
Compact Assembly
Fits into tight machine envelopes, removing the need for a separate valve island and freeing up valuable panel space.
Retrofit Automation
Simplifies machine upgrades by integrating the 5/2 valve directly on the cylinder, minimizing external pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X50-08A the Right Choice?
Choose this 32mm bore when compact force is needed; step up to the 40mm bore for 628N push at 0.5 MPa if load demands increase. The self-valved SAIF32X50-08A excels over a separate cylinder and remote valve in space-tight machines by cutting tubing and wiring. For exact replacements, match the 50mm stroke, 1/4 valve port, AC220V terminal coil, PT thread, and standard carbon steel rod. As the stroke is under 300mm, standard mounting handles guidance without extra side-load concerns.
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 SAIF32X50-08A FAQ
The 32mm bore provides 402N push force at 0.5 MPa and 724N at 0.9 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89.
Yes, the factory setting retracts the rod when the AC220V coil is energised, but you can reposition the 5/2 valve to extend-when-energised. No separate remote valve is needed.
