Airtac SAIF Series Standard Cylinder with Valve SAIF63X500-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X500-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 500mm 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 SAIF63X500-08B
The AirTAC SAIF63X500-08B is a double-acting ISO 15552 profile cylinder paired with a built-in 4M310-08 5/2 solenoid valve. Delivering a Cv of 1.40 and a 25.0 mm2 effective area, this integrated manifold block eliminates the need for a remote valve station. The unit is driven by a DC24V terminal entry coil consuming 3.0 W, protected to IP65, and responds in 0.05 s. Because the valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF is 0.15-0.8 MPa rather than the 1.0 MPa max of the bare cylinder.
At 0.5 MPa it generates 1559 N of push force and 1402 N of pull force. The factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the 3/8 inch cylinder port is distinct from the 1/4 inch valve port. This decentralized design requires only one electrical signal to drive the motion, drastically reducing plumbing and panel space across large machines.

| 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 SAIF63X500-08B Is Used
Decentralized Automation
Ideal for large machine layouts where running separate valve tubing is costly, allowing independent stations to switch themselves via a single DC24V signal.
Space-Constrained Handling
The integrated 4M310 valve manifold saves panel space while delivering 1559 N of push force for compact material handling tasks.
Retrofit Installations
Perfect for upgrading existing lines where adding a remote valve bank is impractical, using the built-in 5/2 valve to control the 500 mm stroke directly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X500-08B the Right Choice?
Choose this 63 mm bore when 50 mm bore thrust (982 N push at 0.5 MPa) is insufficient, or step up to an 80 mm bore (2513 N push at 0.5 MPa) if your load requires significantly more force. The self-valved SAIF architecture is ideal for decentralized stations where running separate valve tubing is costly or space-prohibitive. For this specific DC24V terminal entry model, ensure your control voltage matches exactly. If your application requires true load-holding without live pressure, note that the 5/2 valve routes air and is not a lock; consider an AirTAC SAIL lock cylinder or BSAI clamp-lock instead. Because the 500 mm stroke is substantial, always use a guide to prevent side-load damage to the rod. Replacement requires matching the 63 mm bore, 500 mm stroke, 1/4 inch valve port, DC24V voltage, terminal entry, PT thread, and no magnet (-S).
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 SAIF63X500-08B FAQ
The 63 mm bore generates 1559 N push and 1402 N pull force at 0.5 MPa. The built-in 4M310-08 valve provides a 25.0 mm2 effective area with a Cv of 1.40.
It uses a 5/2 solenoid valve that holds position by pilot pressure. The factory setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. No separate remote valve is needed.
