Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 250mm stroke and a built-in 4M310-10 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 SAIF80X250S-10A
The AirTAC SAIF80X250S-10A is a double-acting ISO 15552 profile cylinder paired with a built-in 4M310-10 5/2 solenoid valve. It delivers a robust 4523N push force at 0.9 MPa and includes a magnet for CMSE and DMSE position sensing. The integrated valve offers a 30.0 mm2 effective area (Cv 1.68) and switches at up to 4 cycles per second. Driven by an AC220V terminal coil drawing 3.5 VA, it activates in 0.05 seconds. The manifold connects to the PT3/8 cylinder port via O10 x O6.5 PU tubing, while the valve itself uses a PT3/8 port.
Because the built-in valve operates from 0.15 to 0.8 MPa, the practical SAIF working range is 0.15-0.8 MPa despite the cylinder body rating of 1.0 MPa. This decentralized design eliminates remote valves and excess plumbing, saving panel space. Factory-set to retract the carbon steel rod when energised, the valve can be repositioned to extend-when-energised if your sequence requires it.

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 SAIF80X250S-10A Is Used
Decentralized Automation Stations
Ideal for large-scale production lines where running individual valve tubing back to a central panel is costly, this self-valved unit operates independently from a single AC220V signal.
Heavy Material Handling
With 4523N of push force at 0.9 MPa, it easily drives heavy lifting and pushing mechanisms in compact machinery without needing external valve infrastructure.
Retrofitted Assembly Lines
Perfect for upgrading existing ISO 15552 interchangeable setups where adding a separate valve island is impractical, utilizing the built-in 4M310-10 valve and PT3/8 ports.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10A the Right Choice?
Choose this 80mm bore when a 50mm bore (982N push at 0.5 MPa) is insufficient but a 100mm bore (3927N push at 0.5 MPa) is oversized. The integrated 4M310-10 valve removes the need for a separate manifold block, cutting wiring and tubing costs across decentralized stations. Since the 5/2 valve routes air rather than mechanically locking it, do not rely on the cushion or valve for position holding under load—select an AirTAC SAIL lock cylinder for true load-holding tasks. When ordering replacements, verify the 250mm stroke, PT3/8 valve port, AC220V terminal coil, and the -S magnet for CMSE/DMSE sensors. For this 250mm stroke, ensure external guides support side loads to prevent rod binding.
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 SAIF80X250S-10A FAQ
The 80mm bore cylinder generates 2513N push and 2268N pull force at 0.5 MPa, reaching 4523N push at 0.9 MPa. The built-in 4M310-10 valve provides a 30.0 mm2 effective area (Cv 1.68) with a maximum operating frequency of 4 cycles per second.
No, the 5/2 solenoid valve routes air but does not lock the piston mechanically. The factory setting retracts the rod when the AC220V coil is energised, but it can be repositioned to extend-when-energised. For true load-holding, use an AirTAC SAIL lock cylinder.
