Airtac SAIF Series Standard Cylinder with Valve SAIF63X50S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X50S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 50mm 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 SAIF63X50S-08A
The AirTAC SAIF63X50S-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40. It includes a magnet for position sensing with CMSE reed and DMSE electronic switches. Driven by an AC220V terminal entry coil consuming 3.5 VA, it responds in 0.05s. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the cylinder body itself rates to 1.0 MPa.
This decentralized unit switches itself from one coil signal, eliminating remote plumbing and saving panel space. The factory setting retracts the carbon steel rod when energized, but you can reposition the valve to extend-when-energised. The manifold connects to the cylinder via PU tubing, keeping the 1/4" valve port distinct from the cylinder's 3/8" port.

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 SAIF63X50S-08A Is Used
Decentralized Assembly Lines
Eliminates remote valve banks by driving the 1559N stroke directly from the built-in 4M310 valve, cutting tubing costs across large machines.
Space-Tight Machinery
The integrated manifold saves valuable panel space while providing precise position feedback via the -S magnet and DMSE sensors.
Retrofit Automation
Ideal for upgrading older machines where running new valve control lines is costly, simply wire the AC220V terminal coil for immediate actuation.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X50S-08A the Right Choice?
Choose this self-valved unit when you need 1559N push force at 0.5 MPa without routing separate valve tubing. If your application requires less force, step down to the 50mm bore offering 982N; for higher force, the 80mm bore provides 2513N. The built-in 4M310 valve flows enough for the 30-800 mm/s speed range.
The AC220V terminal coil suits standard plant voltage. Remember, the 5/2 valve routes air but does not hold the load without live pressure; for true mechanical locking, select a SAIL cylinder. To replace this unit, match the 63mm bore, 50mm stroke, 1/4" valve port, AC220V terminal coil, PT thread, 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 SAIF63X50S-08A FAQ
At 0.5 MPa, the 63mm bore provides 1559N of push force and 1402N of pull force. The maximum force is 318 kgf at 1.0 MPa, though the practical operating pressure is limited to 0.15-0.8 MPa by the built-in 4M310 valve.
It features a 4M310-08 5/2 solenoid valve with a Cv of 1.40. By default, the factory setting retracts the rod when the AC220V coil is energized, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
