Airtac SAIF Series Standard Cylinder with Valve SAIF100X450-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X450-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 450mm 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 SAIF100X450-08B
The AirTAC SAIF100X450-08B 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. Driven by a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 s or less with an IP65 rating. While the bare cylinder rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, setting the practical working range for this assembly. It delivers a robust 3927 N push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The manifold connects the valve to the cylinder using O10 x O6.5 PU tubing. This self-switching design eliminates remote plumbing, saving panel space and making it ideal for decentralized stations across large machines.

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 SAIF100X450-08B Is Used
Decentralized Assembly Lines
Eliminates the need for long air runs from a central control panel. The integrated DC24V valve directly controls the 100mm bore for heavy pushing tasks.
High-Force Clamping Stations
Provides 3927 N of push force at 0.5 MPa. Ideal for securing heavy workpieces directly at the machining station without external valves.
Retrofit Large Machinery
Perfect for upgrading space-tight equipment where running dedicated valve tubing is costly. The terminal coil keeps wiring simple and localized.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X450-08B the Right Choice?
Choose this 100mm bore when you need high thrust, as it generates 3927 N push at 0.5 MPa; stepping down to a 80mm bore drops the push force to 2513 N. A self-valved SAIF is superior to a separate cylinder and remote valve when you want to minimize wiring and tubing in decentralized layouts. Remember that the built-in 5/2 valve routes air but does not hold the load without live pressure; for true mechanical locking, consider the SAIL series. When replacing this unit, match the 450mm stroke, 1/2" cylinder port, 1/4" valve port, DC24V voltage, terminal entry, PT threads, and standard carbon steel rod. For this 450mm stroke, ensure external guides are used to manage side loads.
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 SAIF100X450-08B FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. It can reach a maximum push force of 7068 N at 0.9 MPa.
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the 4M310-08 valve on the manifold block to extend-when-energised. No separate remote valve is needed.
