Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 400mm 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 SAIF80X400-08A
The AirTAC SAIF80X400-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with an AC220V terminal connection and delivers a robust 2513N push force at 0.5MPa. Because the cylinder rates to 1.0MPa but the built-in valve operates from 0.15-0.8MPa, the practical working range for this assembled unit is 0.15-0.8MPa.
By mounting the valve directly via a manifold block and PU tubing, it eliminates the need for a separate remote valve, saving valuable panel space and simplifying decentralized installation across large machines. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve 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)
| 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 SAIF80X400-08A Is Used
Decentralized Automation
Perfect for large factory layouts where installing a central valve bank is impractical, allowing local cylinder control via a single AC220V signal.
High-Force Clamping
Delivers 2513N of push force at 0.5MPa, suitable for securely holding heavy workpieces during machining or welding processes.
Retrofits & Upgrades
Ideal for machinery upgrades where minimizing new plumbing is critical; the integrated valve drastically cuts required tubing and wiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X400-08A the Right Choice?
Choose this 80mm bore when 50mm (982N at 0.5MPa) is insufficient but 100mm (3927N at 0.5MPa) is oversized for your space. The self-contained 4M310 valve (Cv 1.40, max 4 cycles/sec) is ideal for decentralized stations where running separate valve tubing is costly. This model uses a PT3/8 cylinder port and a PT1/4 valve port. Remember, the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL series. With a 400mm stroke, ensure adequate guiding to prevent excessive side loads.
To replace this unit, match the 80mm bore, 400mm stroke, 08 (1/4) valve port, AC220V voltage, terminal entry, PT thread, and standard carbon steel rod. It operates without a magnet, so CMSE or DMSE sensors cannot be used without a different SKU.
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 SAIF80X400-08A FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5MPa. The built-in 4M310-08 valve provides an effective area of 25.0mm2 (Cv 1.40) with a maximum operating frequency of 4 cycles per second.
Yes, by default the coil energizes to retract the rod, but the 5/2 valve can be repositioned to extend-when-energised. This AC220V terminal-connected valve eliminates the need for a separate remote valve, operating safely within the 0.15-0.8MPa range.
