Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-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 SAIF80X400S-08A
The AirTAC SAIF80X400S-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and an effective area of 25.0 mm2. Driven by an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05 s or less. While the bare cylinder rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working range for the assembled unit. It generates 2513 N of push force at 0.5 MPa.
By switching itself from a single coil signal, this unit eliminates remote plumbing and saves panel space, making it ideal for decentralized stations. The manifold connects to the cylinder via O10 x O6.5 PU tubing, and the factory setting retracts the rod when energized, which can be reconfigured to extend-when-energised by repositioning the valve. The carbon steel piston rod includes a magnet for CMSE reed and DMSE electronic sensors.

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 SAIF80X400S-08A Is Used
Decentralized Automation
Perfect for large machine grids where running individual valve tubing back to a central panel is costly, as the integrated 4M310 valve handles switching locally.
High-Force Clamping
Delivers 2513 N of push force at 0.5 MPa for securing heavy workpieces during machining, utilizing the built-in valve for rapid 4 cycle/sec actuation.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 dimensional installations where adding a separate solenoid bank is physically constrained, using the AC220V terminal connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-08A the Right Choice?
Choose this 80mm bore when a 63mm cylinder is insufficient, offering 1559 N push force at 0.5 MPa compared to this unit's 2513 N. The self-valved SAIF design beats a separate cylinder and remote valve in space-tight machines by consolidating control directly on the manifold. For this 400mm stroke, ensure adequate side-load guidance to prevent rod binding. The 5/2 valve routes air but does not lock the load; if position holding is required without live pressure, consider an AirTAC SAIL lock cylinder. Replacement matches require an 80mm bore, 400mm stroke, PT1/4 valve port, AC220V terminal coil, PT threads, and the -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 SAIF80X400S-08A FAQ
The 80mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve provides an effective area of 25.0 mm2 with a Cv of 1.40.
No separate remote valve is needed; the unit switches itself from one AC220V coil signal. The factory default retracts the rod when energized, but it can be reconfigured to extend-when-energised by repositioning the valve.
