Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 400mm 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 SAIF63X400S-08A
The AirTAC SAIF63X400S-08A 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 area. Driven by an AC220V terminal coil consuming 3.5 VA, it activates in 0.05 s with IP65 protection. The integrated valve routes air through O10 x O6.5 PU tubing, meaning one coil signal switches the cylinder directly without remote plumbing. This decentralized architecture saves panel space across large machines. The cylinder bore is 3/8" while the valve port is 1/4".
Although the cylinder body rates to 1.0 MPa, the practical operating range for this valved unit is 0.15-0.8 MPa. It delivers 1559 N of push force at 0.5 MPa and 2805 N at 0.9 MPa. Factory set to retract the rod when energised, the valve can be repositioned to extend-when-energised. A -S magnet is included for precise position detection with CMSE reed and DMSE electronic sensors.

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 SAIF63X400S-08A Is Used
Decentralized Automation
Ideal for large factory layouts needing localized actuation, eliminating long tubing runs to a central manifold.
Extended Stroke Clamping
Provides 1559N push force over a 400mm stroke for positioning heavier workpieces on machining lines.
Space-Constrained Retrofits
Perfect for machine upgrades where adding external valve islands is physically or economically unviable.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-08A the Right Choice?
Choose this 63mm bore when 50mm falls short—yielding 1559 N push at 0.5 MPa versus 982 N—or when 80mm is excessive. The 4M310 valve offers 4 cycles/sec. The 400mm stroke requires external guide support to prevent rod side-loading. The built-in valve switches itself from one signal, eliminating separate valves. It does not hold loads unpowered; use SAIL for locking. To replace: match bore, 400mm stroke, 1/4" valve port, AC220V terminal coil, PT threads, 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 SAIF63X400S-08A FAQ
The cylinder provides 1559 N push and 1402 N pull force at 0.5 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40).
Yes. The factory setting retracts the rod when the AC220V coil is energised, but you can reposition the 5/2 valve to extend-when-energised. No separate remote valve is needed.
