Airtac SAIF Series Standard Cylinder with Valve SAIF63X125S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X125S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 125mm 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 SAIF63X125S-08A
The AirTAC SAIF63X125S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Equipped with a magnet for position sensing, it works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The bundled valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and operates at 4 cycles per second. Driven by an AC220V terminal-entry coil consuming 3.5 VA, it activates in 0.05 seconds. While the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa.
This decentralized unit switches itself from a single coil signal, eliminating remote plumbing and saving panel space. The manifold connects the valve to the cylinder via PU tubing (O10 x O6.5). It delivers 1559 N of push force at 0.5 MPa. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal. The 5/2 valve holds position via internal pilot pressure, not a spring, but it will not lock a load without live air.

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 SAIF63X125S-08A Is Used
Decentralized Machine Stations
Eliminate long air lines from a central panel by placing this self-valved cylinder directly at remote workstations on large assembly lines.
Compact Clamping Fixtures
Save valuable tooling envelope space by integrating the 4M310 valve directly on the 63mm bore actuator for mid-force clamping tasks.
Retrofit Automation Upgrades
Drop-in ISO 15552 interchangeability and built-in solenoid control make it ideal for upgrading older machines where running new valve tubing is costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X125S-08A the Right Choice?
Choose this 63mm bore when 50mm outputs (982 N push at 0.5 MPa) are insufficient, or step down from 80mm (2513 N) to save space. The self-valved SAIF design beats a separate cylinder and remote valve in tight layouts by cutting tubing and wiring. For load-holding, note this valve routes air but does not brake; consider AirTAC SAIL for locking. To replace this unit, match bore 63, stroke 125, valve port 08, AC220V, terminal entry, PT thread, and the -S magnet. At 125mm stroke, side-load stress is minimal, but ensure standard guide support for heavier loads.
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 SAIF63X125S-08A FAQ
The 63mm bore generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
Yes. The factory setting retracts the piston rod when the AC220V coil is energised, but you can reposition the 5/2 valve on the manifold block to extend-when-energised. Because it is a pilot-held 5/2 valve, no separate remote valve is needed.
