Airtac SAIF Series Standard Cylinder with Valve SAIF63X250S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X250S-10A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 250mm stroke and a built-in 4M310-10 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 SAIF63X250S-10A
The AirTAC SAIF63X250S-10A is a double-acting ISO 15552 profile cylinder fitted with a built-in 4M310-10 5/2 solenoid valve, delivering a Cv of 1.68 and a 30mm effective cushion. Driven by an AC220V terminal connection coil drawing 3.5 VA, it activates in 0.05s. The integrated valve operates at 0.15-0.8 MPa, making this the practical working range for the assembled unit even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it generates 1559N of push force.
By switching itself from a single coil signal, this unit eliminates remote plumbing and is ideal for decentralized stations across large machines. The manifold connects the valve to the cylinder via PU tubing (O10 x O6.5). Factory set to retract the carbon steel piston rod when energised, the valve can be repositioned to extend on signal. The -S magnet works with AirTAC CMSE reed and DMSE electronic sensors for position feedback.

| 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 SAIF63X250S-10A Is Used
Decentralized Automation
Ideal for large factory layouts where running individual valve lines is costly, letting each station control its own rod movement from a single AC220V signal.
Mid-Force Assembly
Provides 1559N of push force at 0.5 MPa for precision clamping and pressing tasks within space-constrained machinery envelopes.
Sensor-Ready Actuation
Equipped with a magnet for CMSE and DMSE switches, offering precise end-of-stroke detection for automated sequencing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X250S-10A the Right Choice?
Choose this self-valved SAIF63X250S-10A when a decentralized machine layout demands minimal tubing and panel space, replacing a separate cylinder and remote valve setup. If you need less push force, the 50mm bore delivers 982N at 0.5 MPa; if your application requires more power, step up to the 80mm bore providing 2513N at 0.5 MPa. For stroke lengths of 250mm and above, ensure you use a guide mechanism to handle side loads and prevent rod damage.
This assembly includes a PT3/8 cylinder port and a 3/8 valve port. To replace this unit, match the 63mm bore, 250mm stroke, 4M310-10 valve, AC220V terminal coil, PT thread, and -S magnet. Note that the built-in 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider the AirTAC SAIL lock cylinder.
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 SAIF63X250S-10A FAQ
The cylinder provides 1559N push and 1402N pull force at 0.5 MPa. The built-in 4M310-10 5/2 valve has an effective orifice of 30.0mm2 (Cv 1.68) and a max frequency of 4 cycles/sec.
It uses an internal pilot 5/2 valve that holds position via pilot pressure, not a spring. Factory set to retract when the AC220V coil energizes, it can be reconfigured to extend-when-energized. This integrated design removes the need for a separate remote valve.
