Airtac SAIF Series Standard Cylinder with Valve SAIF63X250-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X250-10A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 250mm stroke and a built-in 4M310-10 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 SAIF63X250-10A
The AirTAC SAIF63X250-10A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific SKU is configured with a PT 3/8 valve port, an AC220V terminal electrical entry, and a carbon steel piston rod. Because the valve is mounted directly via a manifold block and O10xO6.5 PU tubing, it switches itself from a single coil signal, eliminating remote plumbing and saving panel space for decentralized machine stations. The integrated valve provides an effective flow area of 30.0 mm2 (Cv 1.68) and operates at up to 4 cycles per second.
While the base cylinder rates to 1.0 MPa, the practical working pressure for this valved assembly is 0.15-0.8 MPa. Delivering 1559 N of push force at 0.5 MPa, it handles substantial loads. By default, the factory setting retracts the rod when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. The assembly operates smoothly across 30-800 mm/s, and the valve holds its position pneumatically via internal pilot, not by a mechanical spring.

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 SAIF63X250-10A Is Used
Decentralized Machine Stations
Eliminates the need to run long valve control tubing across a large machine. The integrated AC220V 4M310 valve directly controls the 63mm cylinder right at the point of operation.
Mid-Force Assembly Presses
Provides 1559 N of push force at 0.5 MPa. Ideal for pressing, clamping, or joining components where a 50mm cylinder lacks power but an 80mm unit is too bulky.
Space-Constrained Retrofitting
Fits into tight machine envelopes by removing the space typically required for a separate remote valve manifold, while maintaining a true ISO 15552 mounting interface.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X250-10A the Right Choice?
Choose this 63mm bore when a 50mm bore yields insufficient force (982 N push at 0.5 MPa) or when stepping down from an 80mm bore (2513 N push at 0.5 MPa) to save envelope space. The self-valved SAIF63X250-10A outperforms a separate cylinder plus remote valve setup by drastically reducing wiring and tubing runs, making it perfect for decentralized stations. Select the AC220V terminal entry for standard mains-powered control panels.
When ordering a replacement, match the 63mm bore, 250mm stroke, 3/8 valve port, AC220V voltage, terminal entry, PT thread, and no-magnet standard rod. Note that the 3/8 port listed is for the valve; the cylinder port itself is also 3/8. For this 250mm stroke, which is 250mm or greater, ensure adequate side-load guidance to prevent rod damage. If true load-holding is required under pressure loss, this 5/2 valve will not lock the load; refer to the SAIL or BSAI clamp-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 SAIF63X250-10A FAQ
The 63mm bore cylinder provides 1559 N of push force and 1402 N of pull force at 0.5 MPa. The built-in 4M310-10 valve has an effective area of 30.0 mm2 (Cv 1.68) and a maximum operating frequency of 4 cycles per second.
No, the SAIF63X250-10A has a built-in 4M310 5/2 valve mounted directly on the cylinder. It operates from a single AC220V coil signal. By factory default, energising the coil retracts the rod, but this can be reconfigured to extend-when-energised by repositioning the valve.
