Airtac SAIF Series Standard Cylinder with Valve SAIF63X700S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X700S-08A 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 SAIF63X700S-08A
The AirTAC SAIF63X700S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a PT1/4 valve port, an AC220V terminal electrical entry, and a -S magnet for CMSE reed or DMSE electronic sensors. The built-in valve provides a Cv of 1.40 and an effective area of 25.0 mm2, driving a robust 1559N push force at 0.5 MPa. Because the valve manifold uses O10xO6.5 PU tubing to bridge to the 3/8 cylinder port, plumbing is minimized.
Although the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. The factory default setting retracts the piston rod when the coil is energized, but you can reposition the valve to extend-when-energised. Switching itself from a single AC220V signal (3.5 VA, IP65, 0.05s response), it eliminates the need for a remote valve, 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 (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 SAIF63X700S-08A Is Used
Decentralized Automation
Ideal for large-scale production lines where installing individual remote valves is impractical. The built-in 4M310 valve lets this 63mm cylinder operate independently from a single AC220V signal.
Extended Stroke Diverting
The 700mm stroke handles long-throw diverting tasks on conveyor systems. Note that at this length, an external guide should be fitted to manage side loads safely.
Space-Constrained Retrofits
Perfect for machinery upgrades where adding a separate valve island is impossible. The manifold and O10xO6.5 PU tubing minimize physical footprint while delivering 1559N of force.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X700S-08A the Right Choice?
Choose this 63mm bore when a 50mm cylinder lacks thrust (the 50mm yields 982N push at 0.5 MPa, while this 63mm provides 1559N) or when an 80mm is unnecessarily bulky (80mm yields 2513N). The self-valved SAIF architecture beats a separate cylinder and remote valve when panel space is tight and running tubing across a large machine is costly. For this 700mm stroke, adding a side-load guide is recommended to prevent rod damage and premature seal wear.
This model includes a magnet for CMSE and DMSE position sensing. Remember that the 5/2 valve routes air and is not a lock; it will not hold a load without live pressure. For true load-holding, consider the SAIL lock variant. To replace this unit, match the 63mm bore, 700mm stroke, 4M310-08 valve, AC220V terminal coil, PT thread, and -S magnet.
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 SAIF63X700S-08A FAQ
At 0.5 MPa, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 and a Cv of 1.40, with a maximum operating frequency of 4 cycles per second.
No separate remote valve is needed; the integrated 4M310 valve switches the cylinder directly from an AC220V terminal coil signal. By factory default, the piston rod retracts when the coil is energized, but this can be reconfigured to extend-when-energised by repositioning the valve.
