Airtac SAIF Series Standard Cylinder with Valve SAIF63X450S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X450S-08B 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-08B
The AirTAC SAIF63X450S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and an effective orifice of 25.0 mm2. Driven by a DC24V terminal entry coil drawing 3.0 W, it activates in 0.05 s or less. While the bare cylinder rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa. It delivers 1559 N of push force at 0.5 MPa, stepping up to 2182 N at 0.7 MPa. The manifold connects to the cylinder via PU tubing (O10 x O6.5).
This unit includes a magnet for CMSE reed and DMSE electronic sensors. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. It switches itself from one coil signal, eliminating remote valves and extra tubing for decentralized machine stations.

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 SAIF63X450S-08B Is Used
Decentralized Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by switching directly from the cylinder body.
Mid-Force Positioning
Provides 1559 N push force at 0.5 MPa for clamping or lifting mid-weight workpieces without a remote valve bank.
Space-Tight Retrofits
Fits into compact machine envelopes where installing a separate directional control valve and manifold is physically impossible.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X450S-08B the Right Choice?
Choose this 63 mm bore if you need more thrust than the 50 mm class (982 N push at 0.5 MPa) but want to avoid the larger 80 mm envelope (2513 N at 0.5 MPa). The self-valved SAIF design beats a separate cylinder plus remote valve when panel space is tight and running tubing across a large machine is costly. The 4M310-08 valve features a 1/4" port, while the cylinder port is 3/8". This model uses a DC24V terminal coil with PT threaded ports and a carbon steel rod. For position feedback, it accepts CMSE or DMSE switches.
Because the stroke is 450 mm, ensure adequate guide support to prevent side-load damage to the rod seals. Note that the built-in 5/2 valve routes air but does not lock the load; for dead-load holding, consider an AirTAC SAIL lock cylinder. To replace this unit, match the 63x450 dimensions, the 4M310-08 valve, DC24V terminal coil, PT threads, and the -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 SAIF63X450S-08B FAQ
It delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
No, the 5/2 valve routes air but does not lock the load; you need a SAIL cylinder for load holding. The DC24V terminal coil draws 3.0 W. By factory default, energising the coil retracts the rod, but you can reposition the valve to make it extend-when-energised.
