Airtac SAIF Series Standard Cylinder with Valve SAIF63X450-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X450-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm 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 SAIF63X450-08B
The AirTAC SAIF63X450-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, a PT1/4 valve port, and a 3/8 cylinder port. Driven by an internal pilot, the 4M310-08 valve provides a 25.0 mm2 effective area (Cv 1.40) and handles up to 4 cycles per second. The manifold links to the cylinder via O10 x O6.5 PU tubing.
While the bare cylinder rates to 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa. In its factory setting, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. The 63 mm bore generates 1559 N of push force at 0.5 MPa, and the unit requires no remote valve, saving panel space for decentralized machine 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 (Ø63mm)

| 0.7 MPa | 2182 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 SAIF63X450-08B Is Used
Decentralized Automation
Eliminates the need for a remote valve bank, allowing independent control of individual stations across a large factory floor using a single DC24V signal.
Material Handling Diverters
Provides 1559 N of push force at 0.5 MPa to actuate diverters and gates on conveyor lines, with the built-in valve reducing pneumatic plumbing complexity.
Space-Constrained Machinery
Fits into tight machine envelopes where a separate cylinder and valve would not fit, offering a 25.0 mm2 flow area directly at the actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X450-08B the Right Choice?
Choose this self-valved SAIF63X450-08B when a 63 mm bore is required to move loads needing around 1559 N of push thrust at 0.5 MPa. If your application requires less force, stepping down to a 50 mm bore yields 982 N push at 0.5 MPa and uses a 4M210 valve; if you need more power, an 80 mm bore provides 2513 N push at 0.5 MPa. The 450 mm stroke falls within standard limits but is long enough that you should account for side-load risks and use appropriate guide rails to prevent rod binding.
This model is ideal for decentralized installations where running air tubing to a remote valve is costly or space-prohibitive. A single DC24V terminal connection drives the cylinder directly. For exact replacements, match the 63 mm bore, 450 mm stroke, 3/8 cylinder port, 4M310-08 valve with PT1/4 valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. Note that the 5/2 valve routes air and is not a lock; if you need fail-safe 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 SAIF63X450-08B FAQ
The 63 mm bore generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
The integrated 5/2 valve is internal piloted and operates on DC24V (3.0 W). By factory default, energizing the coil retracts the rod, but it can be reconfigured to extend-when-energised. The valve routes air and is not a locking mechanism; it will not hold the load without live pressure.
