Airtac SAIF Series Standard Cylinder with Valve SAIF63X450S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X450S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 450mm 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 SAIF63X450S-08A
The AirTAC SAIF63X450S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve delivers a Cv of 1.40 and operates at a maximum frequency of 4 cycles per second. Supplied with a carbon steel piston rod and a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic solid-state switches. Driven by an AC220V terminal coil drawing 3.5 VA with IP65 protection and a 0.05s activation time, it switches itself from a single electrical signal.
While the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. At 0.5 MPa it generates 1559N of push force and 1402N of pull force. The manifold connects the valve to the cylinder using PU tubing (O10 x O6.5). Note that the valve port is 1/4 (code 08) while the cylinder port is 3/8. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised. This decentralized design eliminates remote valves and excess plumbing.

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)

| 0.7 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 SAIF63X450S-08A Is Used
Decentralized Automation Cells
Ideal for large machines where running individual valve lines is costly. The built-in 4M310-08 valve lets this 63mm cylinder operate independently from a single AC220V signal.
Mid-Force Assembly Stations
Provides 1559N of push force at 0.5 MPa. The 450mm stroke handles extended travel for part manipulation and clamping tasks in tight workspaces.
Sensor-Ready Positioning
Equipped with a standard magnet (-S) for precise end-of-stroke detection using CMSE reed or DMSE solid-state sensors along the profile barrel.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X450S-08A the Right Choice?
Choose this self-valved SAIF unit to slash tubing and panel space in decentralized machine layouts. If your application requires less force, the 50mm bore neighbor provides 982N push at 0.5 MPa; if you need more power, the 80mm bore offers 2513N. This specific model uses an AC220V terminal connection with PT threaded ports. To replace it, match the 63mm bore, 450mm stroke, 4M310-08 valve, AC220V voltage, terminal entry, and the -S magnet.
Because the 450mm stroke exceeds 300mm, ensure adequate guide support to prevent rod side-loading and premature seal wear. Remember that the built-in 5/2 valve routes air but does not lock the load mechanically; if you need true position holding without live pressure, consider the SAIL lock series 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 SAIF63X450S-08A FAQ
At 0.5 MPa, the 63mm bore generates 1559N push and 1402N pull force. The integrated 4M310-08 5/2 valve provides 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 on the manifold block to extend-when-energised. No separate remote valve is needed.
