Airtac SAIF Series Standard Cylinder with Valve SAIF63X125-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X125-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 125mm 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 SAIF63X125-08B
The AirTAC SAIF63X125-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry that consumes 3.0 W, protected to IP65 with a 0.05 s response time. The built-in valve offers a 25.0 mm2 effective area (Cv 1.40) and routes air through a PU tube (O10 x O6.5) to the cylinder's PT3/8 port. Because the valve operates at 0.15-0.8 MPa, this defines the practical working range for the assembled unit, even though the cylinder body rates to 1.0 MPa.
Providing 1559 N push force at 0.5 MPa, this self-switching unit eliminates the need for a separate remote valve, drastically reducing panel space and plumbing. It is factory set to retract the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if the machine sequence demands it. The carbon steel piston rod and standard PT tapered threads ensure robust, leak-free operation across the 30-800 mm/s speed range.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF63X125-08B Is Used
Decentralized Automation
Perfect for large factory layouts where installing a remote valve island is impractical, saving wiring and plumbing time by actuating the cylinder directly at the station.
Material Handling
Provides the 1559 N push force needed to divert or lift heavy packages on conveyor lines, utilizing the built-in 5/2 valve for rapid 4 cycle/sec actuation.
Machine Retrofitting
Ideal for upgrading existing ISO 15552 interchangeable setups where adding a separate valve manifold would consume too much envelope space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X125-08B the Right Choice?
Choose this 63mm bore SAIF when your application requires the 1559 N push force at 0.5 MPa and you want to step up from the 50mm bore (982 N push). It is ideal for decentralized stations across large machines where running individual valve tubing is costly; one DC24V wire signal drives the cylinder directly. If you need load holding without live pressure, note that this 5/2 valve routes air but does not lock the load—consider AirTAC SAIL for pneumatic locking. To order a replacement, match the 125mm stroke, PT3/8 cylinder port, 4M310-08 valve (1/4" port code), DC24V terminal coil, 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 SAIF63X125-08B FAQ
At 0.5 MPa, this 63mm bore cylinder provides 1559 N of push force and 1402 N of pull force. The integrated 4M310-08 valve has a Cv of 1.40 (25.0 mm2 orifice) to support speeds up to 800 mm/s.
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the 5/2 valve on the manifold block to extend-when-energised. This self-contained switching means no separate remote valve is required.
