Airtac SAIF Series Standard Cylinder with Valve SAIF63X200S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X200S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 200mm 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 SAIF63X200S-08A
The AirTAC SAIF63X200S-08A is a double-acting ISO 15552 profile cylinder that integrates a 4M310-08 5/2 solenoid valve directly onto its manifold. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a Cv of 1.40 and activates in 0.05 s. Because the cylinder body rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The carbon steel rod provides a push force of 1559 N at 0.5 MPa.
By controlling itself from a single electrical signal, it eliminates remote plumbing and saves panel space, making it ideal for decentralized machine stations. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the factory setting retracts the rod when the coil is energised, though you can reposition the valve to extend-when-energised. This -S variant includes a magnet for 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)

| 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 SAIF63X200S-08A Is Used
Decentralized Automation Cells
Distributes control logic across large machinery without running long valve tubing back to a central manifold.
Mid-Force Clamping Stations
Provides 1559 N of push force at 0.5 MPa for securing workpieces during machining operations.
Space-Constrained Retrofits
Simplifies machine upgrades where adding a separate valve island is physically or electrically impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X200S-08A the Right Choice?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is insufficient but an 80 mm bore (2513 N push) is excessive. The self-valved SAIF architecture beats a separate cylinder and remote valve in space-tight machines by consolidating air routing and wiring into one decentralized node. This specific SKU uses a PT1/4 cylinder port, a 1/4" valve port, an AC220V terminal connection, and a magnet for position sensing. For exact replacements, match the 63x200 dimensions, 4M310-08 valve, AC220V terminal coil, PT thread, and -S magnet.
At 200 mm stroke, side loads are moderate, but ensuring proper guide alignment will maximize seal life. Note that the 5/2 valve routes air and the cushions only decelerate near stroke end; neither holds the load without live pressure. For true mechanical load-holding, consider an AirTAC SAIL lock cylinder instead.
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 SAIF63X200S-08A FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The integrated 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
No separate pilot is needed; the 4M310 valve is internally piloted. It holds its last position via pilot pressure, not a spring, so it is not a load-holding lock. The factory default retracts the rod when the AC220V coil is energised, but you can reposition the valve to extend-when-energised.
