Airtac SAIF Series Standard Cylinder with Valve SAIF63X800S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X800S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 800mm 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 SAIF63X800S-08B
The AirTAC SAIF63X800S 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 and a 25.0 mm2 effective orifice. Driven by a DC24V terminal entry coil consuming 3.0 W, it achieves IP65 protection and a 0.05 s activation time. The cylinder body features a PT3/8 port, while the integrated valve utilizes a PT1/4 port connected via O10 x O6.5 PU tubing. Because the 4M310 valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa.
This configuration delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa. The integrated manifold eliminates the need for a remote valve, saving panel space and making it ideal for decentralized stations across large machines. Out of the box, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for position feedback.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF63X800S-08B Is Used
Decentralized Assembly Lines
Eliminates the need for long tubing runs from a central valve island, allowing independent DC24V control at each station.
Material Handling Gates
Provides 1559 N of push force at 0.5 MPa to actuate heavy sorting gates directly at the conveyor edge without a separate valve.
Space-Constrained Retrofits
The integrated 4M310 valve and manifold block minimize physical envelope, ideal for upgrading tight machinery where adding external valves is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X800S-08B the Right Choice?
Choose this 63mm bore when a 50mm bore (982 N push at 0.5 MPa) is insufficient and an 80mm bore (2513 N push at 0.5 MPa) would be excessive. The self-valved SAIF design beats a separate cylinder and remote valve setup by cutting plumbing complexity and wiring down to a single DC24V coil signal. For replacement, match the 63mm bore, 800mm stroke, 08 (1/4) valve port, DC24V voltage, terminal entry, PT thread, and -S magnet. Because the stroke is 800mm, ensure adequate guiding to prevent excessive side loads on the rod. Note that the built-in 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, consider the SAIL lock or BSAI clamp-lock variants.
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 SAIF63X800S-08B FAQ
The 63mm bore generates 1559 N push and 1402 N pull at 0.5 MPa. The built-in 4M310-08 valve has a 25.0 mm2 orifice with a Cv of 1.40, supporting a max frequency of 4 cycles/sec.
The integrated 5/2 solenoid valve holds its position via internal pilot pressure, not a spring. The factory default retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
