Airtac SAIF Series Standard Cylinder with Valve SAIF80X800S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X800S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 800mm 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 SAIF80X800S-08A
The AirTAC SAIF80X800S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40. Driven by an AC220V terminal coil consuming 3.5 VA, it integrates pneumatic and electrical control into one assembly. The base cylinder rates to 1.0 MPa, but the integrated valve limits the practical working pressure to 0.15-0.8 MPa.
This 80mm bore unit generates 3518N of push force at 0.7 MPa. It includes a magnet for CMSE reed and DMSE electronic sensors. By default, the piston rod retracts when the coil is energised; this can be reconfigured to extend-when-energised by repositioning the valve. The manifold uses O10xO6.5 PU tubing, and the valve's 1/4" port differs from the cylinder's 3/8" port.

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 SAIF80X800S-08A Is Used
Decentralized Assembly Lines
Eliminates remote valve plumbing across large machines, driving 80mm bore actuation directly from a single AC220V signal at each station.
Heavy Material Handling
Provides 3518N push force at 0.7 MPa for moving substantial fixtures, using the built-in 4M310-08 valve to cycle at up to 4 cycles per second.
Space-Constrained Machinery
Saves valuable panel space by mounting the 5/2 valve directly on the ISO 15552 profile cylinder via a compact manifold block.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X800S-08A the Right Choice?
Choose this 80mm model for heavy loads requiring 3518N push force at 0.7 MPa; step down to the 63mm bore (2182N push at 0.5 MPa) if your load is lighter. A self-valved SAIF beats a separate cylinder and remote valve by eliminating panel space and tubing, making it perfect for decentralized stations. The 800mm stroke requires a side-load guide to prevent rod damage.
This configuration uses an AC220V terminal entry coil with PT tapered threads. The 5/2 valve routes air but does not lock the load; for position holding, consider an AirTAC SAIL lock cylinder. To replace this unit, match the 80mm bore, 800mm stroke, 1/4" valve port, AC220V terminal coil, 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 SAIF80X800S-08A FAQ
At 0.7 MPa, this 80mm bore cylinder generates 3518N of push force and 2268N of pull force. The integrated 4M310-08 valve provides a Cv of 1.40 with a 25.0mm effective orifice to handle the required airflow.
No, the 5/2 solenoid valve routes air but does not lock the load. It operates on internal pilot pressure and holds its last position via pilot, not a spring. For true position holding, an AirTAC SAIL lock cylinder is required.
