Airtac SAIF Series Standard Cylinder with Valve SAIF63X175S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X175S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 175mm 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 SAIF63X175S-08A
The AirTAC SAIF63X175S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides a Cv of 1.40 and an effective area of 25.0 mm2, driving the 63mm bore to deliver 1559N of push force at 0.5 MPa. Equipped with a carbon steel piston rod and an -S magnet for CMSE reed or DMSE electronic sensors, it operates on an AC220V terminal connection consuming 3.5 VA. Because the manifold relies on internal pilot pressure, the practical working range for this valved assembly is 0.15-0.8 MPa, despite the bare cylinder rating of 1.0 MPa.
By default, 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. This decentralized design eliminates the need for a separate remote valve, drastically reducing panel space and tubing runs. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port (1/4 inch) is intentionally smaller than the 3/8 inch cylinder port to optimize flow control for the 4M310 valve.

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 SAIF63X175S-08A Is Used
Decentralized Assembly Lines
Perfect for large-scale automated machinery where installing individual remote valves is impractical, allowing each station to control its own actuation locally.
Mid-Force Clamping Fixtures
Provides reliable 1559N clamping force at 0.5 MPa for machining cells, eliminating the need for external valve plumbing in tight workholding spaces.
Retrofit Machine Upgrades
Ideal for upgrading older pneumatic systems by bundling the cylinder and valve into one unit, minimizing rewiring and new tube routing during modernization.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X175S-08A the Right Choice?
Choose this 63mm bore when a 50mm bore (offering 982N push at 0.5 MPa) is underpowered, but an 80mm bore (2513N push at 0.5 MPa) would be physically oversized for your machine. The SAIF63X175S-08A is ideal for decentralized stations where running separate valve tubing back to a main manifold is costly or impractical. The AC220V terminal entry provides a straightforward hardwired connection, and the PT tapered threads ensure a reliable, sealed pneumatic joint.
Since the stroke is 175mm, side-load is minimal, but always ensure proper guide alignment for smooth operation. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding against gravity or drop pressure, consider the AirTAC SAIL lock cylinder or BSAI clamp-lock variant instead. When ordering a replacement, verify the 63mm bore, 175mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, PT threads, and the -S magnet option.
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 SAIF63X175S-08A FAQ
The 63mm bore generates 1559N of push force and 1402N of pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 and a Cv of 1.40.
No, the integrated 4M310 valve switches the cylinder directly from one AC220V coil signal. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
