Airtac SAIF Series Standard Cylinder with Valve SAIF32X400-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X400-08A 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 SAIF32X400-08A
The AirTAC SAIF32X400-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This specific SKU is configured with an AC220V terminal coil and delivers a Cv of 0.89 with a 16.0 mm2 orifice. Because the integrated valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembly, even though the bare cylinder rates to 1.0 MPa. It yields 402N of push force at 0.5 MPa.
By controlling itself from a single electrical signal, it eliminates remote plumbing and saves panel space, making it perfect for decentralized machine stations. The manifold connects to the cylinder via PU tubing (O8 x O5), and the valve port (1/4") differs from the cylinder port (1/8"). Factory set to retract the rod when the coil energises, the valve can be physically repositioned to extend-when-energised if your cycle logic requires it.

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 SAIF32X400-08A Is Used
Decentralized Assembly Stations
Ideal for large machines where running individual valve lines back to a central manifold is costly and space-prohibitive.
Material Handling Gates
Provides self-switching actuation for sorting gates, reducing response time and simplifying pneumatic plumbing.
Compact Clamping Fixtures
Integrates the valve directly on the cylinder body to save valuable fixture space while delivering 402N of clamping force.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X400-08A the Right Choice?
Choose this 32mm bore if your application requires around 402N push force at 0.5 MPa; stepping up to the 40mm bore raises that to 628N. A self-valved SAIF excels over a separate cylinder plus remote valve when you need to minimize tubing across a large machine. To replace this unit, match the 32mm bore, 400mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and standard carbon steel rod. Since this model has a 400mm stroke, ensure you use a guide to prevent side-load damage to the profile barrel and seals. Note that the 5/2 valve routes air and is not a lock; for load-holding, consider the SAIL series.
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 SAIF32X400-08A FAQ
The 32mm bore generates 402N push force and 345N pull force at 0.5 MPa. The built-in 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
Yes. The factory setting retracts the piston rod when the AC220V coil is energised, but you can reposition the 5/2 valve on the manifold block to extend-when-energised. This self-contained design means no separate remote valve is required.
