Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm 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 SAIF80X75S-08B
The AirTAC SAIF80X75S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, providing a Cv of 1.40 and an effective area of 25.0 mm2. It features a 80mm bore generating 2513N of push force at 0.5 MPa, paired with a carbon steel rod and a -S magnet for CMSE reed and DMSE electronic sensors. Driven by a DC24V terminal coil consuming 3.0 W with IP65 protection and a 0.05 s response time, it eliminates the need for a remote valve bank.
Because the integrated 4M310 valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa despite the cylinder body rating of 1.0 MPa. 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 energised, the valve can be repositioned to extend on signal, making it ideal for decentralized machine 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)

| 0.7 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 SAIF80X75S-08B Is Used
Decentralized Automation
Perfect for large machines with decentralized stations, eliminating long tubing runs to a central panel by switching itself via the integrated 4M310 valve.
High-Force Clamping
Delivers 2513N of push force at 0.5 MPa directly at the workpiece, ideal for heavy-duty clamping tasks where space for external valves is tight.
Streamlined Retrofits
Simplifies machine upgrades by replacing a standard cylinder and remote plumbing with a single self-valved unit requiring only one DC24V electrical signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08B the Right Choice?
Select this 80mm bore model when an application requires substantial thrust, such as the 2513N push force at 0.5 MPa, but you want to avoid the plumbing of a separate valve. If you need less force, stepping down to a 63mm bore yields 1559N push at 0.5 MPa; if you need more, the 100mm bore offers 3927N. The self-contained DC24V terminal coil design drastically cuts wiring and panel space compared to a traditional cylinder plus remote valve setup.
For load-holding applications, note that the 5/2 valve routes air but does not lock the load without live pressure, and the air cushion only decelerates near stroke end. For true mechanical holding, consider the SAIL lock or BSAI clamp-lock series. When ordering a replacement, verify the 80mm bore, 75mm stroke, 1/4 valve port, DC24V terminal coil, PT tapered threads, and the -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 SAIF80X75S-08B FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
Yes. The factory setting retracts the piston rod when the DC24V coil is energised, but the 5/2 valve can be repositioned to extend the rod upon energisation. This self-switching design removes the need for a separate remote valve.
