Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 50mm 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 SAIF80X50-08A
The AirTAC SAIF80X50-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Driven by an AC220V terminal coil consuming 3.5 VA, it delivers a robust 2513N push force at 0.5 MPa. The built-in valve offers a 25.0mm2 effective area (Cv 1.40) and switches up to 4 cycles per second. Because the cylinder body rates to 1.0 MPa but the valve operates 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
This self-contained design eliminates the need for a separate remote valve, reducing panel space and PU tubing runs for decentralized installations. The manifold connects to the cylinder via O10xO6.5 tubing, while the valve itself uses a 1/4" port distinct from the cylinder's 3/8" port. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The standard carbon steel rod and PT tapered threads ensure durable, leak-free pneumatic connections.

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 SAIF80X50-08A Is Used
Decentralized Automation
Ideal for large machines with multiple stations, using the built-in valve to cut down on remote valve manifold plumbing and extensive tubing runs.
High-Force Clamping
Delivers 2513N of push force at 0.5 MPa for securing heavy workpieces, operating efficiently within the 0.15-0.8 MPa valve pressure range.
Compact Machine Retrofits
Perfect for upgrading existing machinery where adding external valve islands is impractical, offering a direct AC220V terminal connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-08A the Right Choice?
Choose this 80mm bore when you need high thrust (2513N push at 0.5 MPa) in a space-constrained, decentralized station, avoiding the plumbing complexity of a remote valve. If your application requires less force, stepping down to a 63mm bore yields 1559N push at 0.5 MPa. If you need even greater thrust, a 100mm bore provides 3927N at 0.5 MPa. The integrated 4M310-08 valve handles the flow efficiently, but remember the 5/2 valve routes air and does not lock the load; for position holding, consider an AirTAC SAIL lock cylinder. When replacing this unit, match the 80mm bore, 50mm stroke, 3/8" cylinder port, 1/4" valve port, AC220V terminal coil, PT threads, and standard non-magnet configuration.
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 SAIF80X50-08A FAQ
At 0.5 MPa, this 80mm bore cylinder generates 2513N of push force and 2268N of pull force. The integrated 4M310-08 5/2 valve provides an effective area of 25.0mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
By factory default, the coil is set so the piston rod retracts when energised. By repositioning the integrated 5/2 valve, you can easily reconfigure it to extend-when-energised. This self-switching design means no separate remote valve is required.
