Airtac SAIF Series Standard Cylinder with Valve SAIF100X450-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X450-08A 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 SAIF100X450-08A
The AirTAC SAIF100X450-08A 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 an AC220V terminal entry coil that consumes 3.5 VA, it activates in 0.05 seconds. The cylinder body rates to 1.0 MPa, but because the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers robust thrust, pushing with 3927N and pulling with 3681N at 0.5 MPa.
By integrating the valve directly on a manifold block via O10 x O6.5 PU tubing, this unit switches itself from a single coil signal, eliminating remote plumbing and saving panel space for decentralized installations. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. Note that the 1/2 inch cylinder port differs from the 1/4 inch valve port. The carbon steel rod and standard PT tapered threads ensure durable, leak-free connections.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF100X450-08A Is Used
Decentralized Automation
Ideal for large factory lines where running air tubing to a central valve bank is costly; the integrated 4M310 valve handles local switching directly at the station.
Heavy Material Forming
Provides substantial 3927N push force at 0.5 MPa for pressing, clamping, or forming rigid materials in tight machine footprints without external valves.
Retrofit & Upgrades
Perfect for upgrading existing ISO 15552 setups where panel space is full, allowing a new actuator station with just a single AC220V wire drop.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X450-08A the Right Choice?
Choose this 100mm bore when you need heavy thrust that smaller neighbours cannot provide; stepping down to an 80mm bore drops the 0.5 MPa push force to 2513N. A self-valved SAIF100X450-08A beats a separate cylinder and remote valve when wiring and space are tight across large machines, as it requires only one electrical signal to drive the actuator. For load-holding applications, remember this 5/2 valve routes air but does not lock the piston; consider an AirTAC SAIL for mechanical locking. When ordering replacements, verify the 450mm stroke, 1/4 inch valve port, AC220V terminal coil, PT threads, and standard carbon steel rod. Since the stroke is 450mm, ensure proper guide rail support to prevent rod side-loading and premature seal wear.
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 SAIF100X450-08A FAQ
At 0.5 MPa, this 100mm bore cylinder delivers 3927N of push force and 3681N of pull force. The built-in 4M310-08 5/2 solenoid valve provides an effective area of 25.0 mm2 (Cv 1.40) and can cycle up to 4 times per second.
No, the 5/2 valve routes air but does not lock the load without live pressure. By default, the factory setting retracts the rod when the AC220V coil is energised, but the valve can be repositioned to extend-when-energised. For true mechanical load holding, consider the AirTAC SAIL series.
