Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08E 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-08E
The AirTAC SAIF80X75S-08E 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. Driven by an AC24V terminal entry coil consuming 3.5 VA, it delivers robust thrust of 2513N push and 2268N pull at 0.5 MPa. The integrated manifold uses O10 x O6.5 PU tubing to bridge the valve and cylinder, eliminating the need for separate remote plumbing.
Because the cylinder body rates to 1.0 MPa but 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 factory setting retracts the piston rod when the coil is energised, though you can reposition the valve to extend-when-energised. This -S variant includes a magnet for CMSE reed and DMSE electronic sensors, and its self-contained switching makes 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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF80X75S-08E Is Used
Decentralized Assembly Lines
Perfect for large machines with decentralized stations, saving panel space by switching directly from an AC24V terminal signal without remote valve banks.
High-Force Clamping Jigs
Provides 2513N of push force at 0.5 MPa for securing heavy workpieces, utilizing the integrated 4M310-08 valve for rapid 4 cycle/sec actuation.
Space-Constrained Retrofits
Ideal for upgrading older pneumatic setups where plumbing new valve tubing is impractical, offering a self-valved ISO 15552 profile body with CMSE/DMSE sensor tracking.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X75S-08E the Right Choice?
Select this 80mm bore when a 63mm cylinder falls short of the 1559N push force at 0.5 MPa, or step down to a 63mm unit if 2513N is excessive for your load. The SAIF80X75S-08E shines in space-constrained retrofits where running separate valve tubing is costly, as one AC24V terminal signal drives the actuator directly. It operates at 30-800 mm/s across its 75mm stroke.
For load-holding applications, remember that the built-in 5/2 valve routes air but does not lock the piston; consider an AirTAC SAIL lock cylinder for fail-safe holding. When ordering a replacement, match the 80mm bore, 75mm stroke, 1/4" valve port, PT thread type, AC24V voltage, terminal entry, and the -S magnet requirement.
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-08E FAQ
At 0.5 MPa, this 80mm bore cylinder delivers 2513N of push force and 2268N of pull force. The integrated 4M310-08 valve manages airflow with a Cv of 1.40 and an effective area of 25.0 mm2.
Yes, the factory setting retracts the rod when the AC24V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the 5/2 valve. This self-contained design eliminates the need for a separate remote valve.
