Airtac SAIF Series Standard Cylinder with Valve SAIF80X175S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X175S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm 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 SAIF80X175S-08A
The AirTAC SAIF80X175S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. This integrated valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and is wired for an AC220V coil with a standard terminal entry. Because the manifold block connects to the cylinder via PU tubing, the valve port (1/4") is distinct from the cylinder port (3/8"). The standard carbon steel rod includes a magnet for CMSE reed and DMSE electronic sensors.
Although the cylinder body rates to 1.0 MPa, the practical operating range for this assembled unit is 0.15-0.8 MPa due to the internal pilot valve limits. Delivering 2513 N of push force at 0.5 MPa, it switches itself from a single coil signal, eliminating remote plumbing. Factory set to retract when energised, the valve can be repositioned to extend on signal, making it ideal for decentralized stations.

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 (Ø80mm)

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAIF80X175S-08A Is Used
Decentralized Machine Stations
Eliminates the need to run long valve tubing from a central panel. The integrated 4M310 valve and AC220V terminal coil let this 80mm bore cylinder operate autonomously at distant machine zones.
High-Force Assembly Actuators
Provides 2513 N of push force at 0.5 MPa directly at the work point. The built-in valve ensures rapid 4 cycle/sec switching without the lag of remote pneumatic lines.
Wiring-Retrofit Upgrades
Ideal for retrofits where adding new pneumatic plumbing is costly. You only need to run a single electrical signal to the terminal entry, simplifying machine updates.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X175S-08A the Right Choice?
Choose this 80mm bore when a 63mm cylinder (1402 N pull at 0.5 MPa) lacks thrust or a 100mm unit is too bulky. The self-valved SAIF architecture is superior to a separate cylinder and remote valve when you need to minimize panel space and tubing runs across a large machine. This 175mm stroke is under the 300mm side-load threshold, but always verify guide alignment. To replace this unit, match the 80mm bore, 175mm stroke, 4M310-08 valve, AC220V terminal coil, PT threads, and the -S magnet.
Remember that the 5/2 valve routes air but does not hold the load without live pressure; it is not a lock. For secure position holding during air loss, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinders 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 SAIF80X175S-08A FAQ
The 80mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The built-in 4M310-08 valve provides a 25.0 mm2 effective area (Cv 1.40) and operates at a maximum frequency of 4 cycles per second.
No, it switches itself using the integrated 4M310 5/2 valve driven by an AC220V terminal coil. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Note that the valve routes air but does not lock the load without pressure.
