Airtac SAIF Series Standard Cylinder with Valve SAIF63X75S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X75S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 75mm 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 SAIF63X75S-08B
The AirTAC SAIF63X75S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal coil drawing 3.0 W, it integrates switching directly on the actuator. The base cylinder rates to 1.0 MPa, but because the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The 63 mm bore generates 1559 N of push force at 0.5 MPa.
This self-contained design eliminates remote valves and extensive plumbing, making it ideal for decentralized stations across large machines. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port (1/4) is distinct from the cylinder port (3/8). Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if needed. The included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for position feedback.

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 SAIF63X75S-08B Is Used
Decentralized Assembly Stations
Perfect for large machines where running individual valve tubing back to a main panel is costly. The integrated 4M310-08 valve lets this 63 mm bore actuator switch itself locally via a single DC24V signal.
Compact Clamping Fixtures
Delivers 1559 N of push force at 0.5 MPa in space-tight machinery. The built-in valve and manifold remove the need for external plumbing, freeing up valuable envelope space around the clamping point.
Retrofit Automation Upgrades
Ideal for upgrading existing lines with ISO 15552 mounting interfaces. The self-contained pneumatic switching simplifies installation while the -S magnet enables drop-in CMSE or DMSE sensor tracking.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X75S-08B the Right Choice?
Choose this 63 mm bore when 50 mm (982 N push at 0.5 MPa) is insufficient, but 80 mm (2513 N) is oversized. The SAIF63X75S-08B excels where a self-valved actuator reduces panel space and wiring compared to a separate cylinder and remote valve. Its DC24V terminal connection offers straightforward, low-power integration into modern control systems. Remember that the 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider the SAIL lock or BSAI clamp-lock series. When ordering replacements, verify the 75 mm stroke, 3/8 cylinder port, 1/4 valve port, DC24V voltage, terminal entry, PT threads, 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 SAIF63X75S-08B FAQ
The 63 mm bore generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
The integrated 5/2 valve is factory set to retract the rod when the DC24V coil is energised, but can be repositioned to extend-when-energised. It eliminates the need for a separate remote valve, but it routes air rather than locking; it cannot hold a load without live pressure.
