Airtac SAIF Series Standard Cylinder with Valve SAIF100X125-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X125-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 125mm stroke and a built-in 4M310-08 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 SAIF100X125-08B
The AirTAC SAIF100X125-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 s with an IP65 rating. The base cylinder features a 1/2 inch cylinder port and a carbon steel rod, while the integrated valve manifold uses a 1/4 inch valve port connected via PU tubing. Because the 4M310 valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa, despite the bare cylinder rating of 1.0 MPa. This 100mm bore generates 7068N of push force at 0.9 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised by simply repositioning the valve. This decentralized design switches itself from one coil signal, eliminating the need for a separate remote valve, reducing plumbing, and saving panel space across large machines. The assembly operates at speeds of 30-800 mm/s and relies on internal pilot pressure to hold its last position, meaning it does not lock the load without live air pressure.

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 (Ø100mm)

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAIF100X125-08B Is Used
Decentralized Automation Stations
Ideal for large machines with decentralized stations, driving heavy 100mm bore loads directly from a single DC24V signal without routing long remote valve lines.
Space-Constrained Machinery
Perfect for compact assemblies where panel space is restricted, using the built-in 4M310-08 valve manifold to eliminate external plumbing and reduce overall envelope.
Retrofit and Upgrades
Simplifies machine retrofits by bundling the cylinder and valve, minimizing the need to run new pneumatic tubing across the factory floor for remote control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X125-08B the Right Choice?
Select this 100mm bore when your application requires high thrust, such as the 5497N push force at 0.7 MPa, and you want to step up from a 80mm bore that provides 3518N at the same pressure. A self-valved SAIF unit is superior to a separate cylinder and remote valve when installation space is tight and running valve tubing is costly, as it integrates the manifold directly on the profile barrel. Choose this specific configuration when you need a DC24V terminal coil with PT tapered threads. To replace this model, match the 100mm bore, 125mm stroke, 1/4 inch valve port, DC24V voltage, terminal entry, and no magnet. For load-holding applications, note that the 5/2 valve routes air but does not lock the load; consider the SAIL series for pneumatic locking.
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 SAIF100X125-08B FAQ
The 100mm bore generates a maximum push force of 7068N at 0.9 MPa and 3927N at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
Yes. The factory default setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. This self-contained design eliminates the need for a separate remote valve.
