Airtac SAIF Series Standard Cylinder with Valve SAIF63X225S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X225S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 225mm 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 SAIF63X225S-08B
The AirTAC SAIF63X225S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. Featuring a 1.40 Cv flow coefficient, this integrated assembly operates on a DC24V terminal coil drawing 3.0 W. The manifold connects the valve to the cylinder via PU tubing (O10 x O6.5). Because the cylinder body rates to 1.0 MPa but the 4M310 valve limits pressure to 0.15-0.8 MPa, the practical working range for the assembled unit is 0.15-0.8 MPa.
This 63mm bore generates 1559N of push force at 0.5 MPa and 2805N at 0.9 MPa. The -S magnet allows position sensing with CMSE reed or DMSE electronic switches. By default, the 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 plumbing for decentralized installations.

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 SAIF63X225S-08B Is Used
Decentralized Automation
Ideal for large machine grids where running individual valve tubing back to a central manifold is costly and consumes excessive panel space.
Mid-Force Positioning
Provides 1559N push force at 0.5 MPa for clamping, lifting, and indexing medium-weight workpieces directly at the point of operation.
Space-Constrained Retrofit
Suits machine upgrades where adding a remote valve island is impractical, using a single DC24V signal to drive the actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X225S-08B the Right Choice?
Choose this self-valved SAIF unit when a decentralized machine station needs 1559N push force at 0.5 MPa without the tubing and panel space of a separate remote valve. If your application requires less force, the 50mm bore neighbor offers 982N push at 0.5 MPa; for heavier loads, the 80mm bore provides 2513N. The 225mm stroke is standard for this bore, but at this length you should consider external guide rails to prevent side-loading and ensure seal longevity.
This model includes a DC24V terminal electrical entry and PT tapered threads. The built-in 5/2 valve routes air to hold the cylinder in its last position via pilot pressure, but it is not a lock; for true load-holding under pressure loss, select the SAIL lock or BSAI clamp-lock cylinder. To replace this unit, match the 63mm bore, 225mm stroke, 08 valve port, DC24V voltage, terminal entry, 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 SAIF63X225S-08B FAQ
The 63mm bore generates 1559N push and 1402N pull force at 0.5 MPa, up to 2805N push at 0.9 MPa. The built-in 4M310-08 5/2 valve has a 25.0 mm2 orifice with a 1.40 Cv flow coefficient.
The integrated 5/2 valve drives the cylinder from a single DC24V signal. By factory default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. The valve holds its last position via pilot pressure but is not a mechanical lock.
