Airtac SAIF Series Standard Cylinder with Valve SAIF63X700-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X700-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 700mm 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 SAIF63X700-08B
The AirTAC SAIF63X700-08B 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 PT3/8 cylinder port. The built-in valve provides a 25.0 mm2 effective area (Cv 1.40) and operates at 0.15-0.8 MPa, which dictates the practical working range for the assembled unit since the cylinder body itself rates to 1.0 MPa.
By driving the cylinder directly from one coil signal, this unit eliminates the need for a remote valve bank, drastically reducing plumbing and panel space for decentralized machine stations. The manifold connects to the cylinder via O10 x O6.5 PU tubing. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it. At 0.5 MPa it yields 1559 N of push force and 1402 N of pull force.

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)

| 0.5 MPa | 1559 N | 1402 N |
| 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 SAIF63X700-08B Is Used
Decentralized Automation
Eliminates remote valve banks on large machines by switching itself locally via the integrated 4M310 valve, saving significant panel and plumbing space.
Long-Stroke Diverting
Provides robust 1559 N push force at 0.5 MPa across a 700 mm stroke to divert heavy packages on conveyor lines without needing external pilot lines.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 interchangeable setups where adding a separate valve island is structurally difficult or expensive to wire.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X700-08B the Right Choice?
Choose this 63 mm bore when a 50 mm bore falls short on thrust (offering 982 N push at 0.5 MPa) or when an 80 mm bore provides excess capacity (2513 N push). The 700 mm stroke operates safely within the 1500 mm maximum standard stroke for this bore, but at this length you must account for side loads and use a guide to prevent rod bending. The DC24V terminal coil offers IP65 protection and a 0.05 s activation time, making it a safe, low-voltage choice for automated equipment.
This self-valved configuration shines in space-tight machines where running tubing back to a central manifold is costly or impractical. Remember that the 5/2 valve routes air and the end cushions only decelerate the piston near stroke end; neither function locks the load. If your application requires true mechanical load-holding, consider an AirTAC SAIL lock cylinder instead. To replace this exact unit, match the 63x700 dimensions, 4M310-08 valve, DC24V terminal coil, PT threads, and standard carbon steel rod.
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 SAIF63X700-08B FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The integrated 4M310-08 5/2 valve features a 25.0 mm2 effective area (Cv 1.40) with a maximum frequency of 4 cycles per second.
This model uses a DC24V terminal coil consuming 3.0 W. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Because the valve is built-in, no separate remote valve is needed to drive the cylinder.
