Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08E 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-08E
The AirTAC SAIF32X400S-08E is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific configuration uses an AC24V terminal coil drawing 3.5 VA, complete with a -S magnet for CMSE reed and DMSE electronic sensors. Because the cylinder body rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. It delivers 402N of push force at 0.5 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, though this can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold connects using O8xO5 PU tubing, and it is important to note the valve port is 1/4" while the cylinder port is 1/8". Switching itself from one coil signal, this unit eliminates remote valves and tubing, making it ideal for decentralized 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 SAIF32X400S-08E Is Used
Decentralized Stations
Perfect for large machines with decentralized stations, eliminating long pneumatic tubing runs by switching directly at the cylinder.
Compact Assembly
Ideal for space-tight machinery where mounting a separate remote valve is impossible, saving valuable panel and framework space.
Retrofit Projects
Suits machine retrofits where adding new valve manifolds is too costly, requiring only a single electrical signal to operate.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X400S-08E the Right Choice?
Choose this 32mm bore if your application requires up to 402N of push force at 0.5 MPa; step up to the 40mm bore if you need 628N. The 400mm stroke on this model requires attention to side-load, so ensure proper guide bearings to prevent rod damage. A self-valved SAIF beats a separate cylinder plus remote valve when panel space is tight and running valve tubing is costly.
For replacements, match the 32mm bore, 400mm stroke, 1/4" valve port, AC24V terminal coil, PT thread, and the -S magnet. Remember that the 5/2 valve routes air and is not a lock; the air cushion only decelerates near stroke end. For true load-holding, consider the SAIL lock or BSAI clamp-lock series instead.
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-08E FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The integrated 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
No, the integrated 5/2 valve switches the cylinder directly from the AC24V coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
