Airtac SAIF Series Standard Cylinder with Valve SAIF63X350S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X350S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 350mm 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 SAIF63X350S-08A
The AirTAC SAIF63X350S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Equipped with a 1/4" valve port, it delivers a Cv of 1.40 and operates on AC220V via a terminal connection. The cylinder bore is 63mm with a 3/8" cylinder port, generating 1559N of push force at 0.5 MPa. A factory-installed magnet (-S) enables position sensing with CMSE reed or DMSE electronic switches.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-contained design eliminates remote plumbing, using a short PU tube (O10 x O6.5) to link the manifold and cylinder, which is 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)
| 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 SAIF63X350S-08A Is Used
Decentralized Assembly Lines
Eliminates the need for long air tubing runs back to a central valve manifold, enabling localized control across large factory layouts.
Space-Constrained Machinery
The integrated 4M310 valve manifold saves critical panel and footprint space in compact automation equipment.
Retrofit Automation
Ideal for upgrading older machines where adding external valve plumbing is costly, relying on a single AC220V coil signal to drive motion.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X350S-08A the Right Choice?
Choose this 63mm bore when a 50mm cylinder lacks thrust (982N push at 0.5 MPa) or a 80mm unit is excessive (2513N push at 0.5 MPa). The self-valved SAIF architecture beats a separate cylinder plus remote valve setup by cutting panel space, wiring, and tubing runs. At 350mm stroke, the unit is susceptible to side loads, so ensure adequate guide rails to prevent rod binding. To replace this unit, match the 63mm bore, 350mm stroke, 4M310-08 valve, AC220V terminal coil, PT threads, and -S magnet. Note that the 5/2 valve routes air and is not a lock; for load-holding, select a SAIL or BSAI 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 SAIF63X350S-08A FAQ
The 63mm bore generates 1559N push and 1402N pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles/sec.
No, it uses a built-in 5/2 solenoid valve driven by an AC220V terminal coil. By factory default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
