Airtac SAIF Series Standard Cylinder with Valve SAIF63X900-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X900-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 900mm 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 SAIF63X900-08A
The AirTAC SAIF63X900-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a PT 1/4 valve port and an AC220V terminal coil connection. The built-in valve delivers a Cv of 1.40 with a 25.0 mm2 effective area, driving the 63mm bore to produce 1559N of push force at 0.5 MPa. 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 integrating the valve directly onto the manifold block via PU tubing, this unit eliminates the need for a remote valve bank, saving panel space and simplifying decentralized installation across large machines. Driven by one coil signal, the factory setting retracts the piston rod when energised, but you can reposition the valve to extend-when-energised if your logic requires it. The cylinder features a carbon steel piston rod and adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIF63X900-08A Is Used
Decentralized Assembly Stations
Ideal for large automated lines where installing individual valve islands is impractical, allowing local AC220V control of clamping operations.
Material Diverters
Provides robust 1559N push force to actuate diverter gates along extended conveyor systems without long pneumatic runs back to a main panel.
Space-Constrained Palletizers
Fits into tight machine envelopes where a separate cylinder and remote valve would exceed available space, streamlining wiring and plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X900-08A the Right Choice?
Choose this 63mm bore when a 50mm bore (offering 982N push at 0.5 MPa) is insufficient, but a 80mm bore (2513N push at 0.5 MPa) would be physically oversized. The 900mm stroke is substantial; for any stroke at or above 300mm, you must account for side-load and implement external guide rails to prevent rod binding and premature seal wear. A self-valved SAIF cylinder is ideal when running separate valve tubing back to a central manifold is costly or impractical, allowing a single AC220V terminal connection to control the actuator locally. If your application requires the rod to hold its position without live air pressure, note that the 5/2 valve routes air but does not lock the load—consider the SAIL series for pneumatic locking requirements. To replace this unit exactly, match the 63mm bore, 900mm stroke, 4M310-08 valve, AC220V voltage, terminal entry, PT thread, and standard non-magnet configuration.
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 SAIF63X900-08A FAQ
The 63mm bore generates 1559N of push force and 1402N of pull force at 0.5 MPa. The integrated 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) and can cycle up to 4 times per second.
Yes. The factory default setting retracts the rod when the AC220V coil is energised, but you can reposition the 5/2 valve on the manifold block to make it extend-when-energised. This eliminates the need for a separate remote valve.
