Airtac SAIF Series Standard Cylinder with Valve SAIF80X800-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X800-08A 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 SAIF80X800-08A
The AirTAC SAIF80X800-08A is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by an AC220V terminal entry coil drawing 3.5 VA, it eliminates the need for a separate remote valve. The unit features a carbon steel piston rod and PT tapered threads. Because the 4M310 valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled SAIF, even though the bare cylinder body rates to 1.0 MPa.
From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it. The manifold connects to the cylinder using O10 x O6.5 PU tubing. At 0.5 MPa it generates 2513 N of push force and 2268 N of pull force, making it a robust choice for decentralized stations across large machines where running individual valve tubing is costly.

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 SAIF80X800-08A Is Used
Decentralized Machine Stations
Ideal for large assembly lines where installing a remote valve bank is impractical, letting each 80mm bore station switch locally via the AC220V terminal signal.
Long-Stroke Material Handling
The 800mm stroke pushes heavy loads with 2513 N force at 0.5 MPa, while the built-in valve minimizes tubing runs along the conveyor frame.
Retrofit Automation
Drops into existing ISO 15552 mounts to upgrade a plain cylinder to self-switching without rewiring a central valve manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X800-08A the Right Choice?
Choose this 80mm bore when a 63mm cylinder (1402 N pull at 0.5 MPa) lacks force, but a 100mm unit is physically too large. The integrated 4M310 valve switches itself from one coil signal, saving panel space and plumbing. An 800mm stroke demands careful side-load management; use a guide rail to prevent rod binding. Remember the 5/2 valve routes air and is not a lock—drop pressure and the load moves. For position holding, select a SAIL lock cylinder. To replace this unit, match the 80mm bore, 800mm stroke, PT1/4 valve port, AC220V terminal coil, and no magnet (-S).
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 SAIF80X800-08A FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513 N push and 2268 N pull force. The integrated 4M310-08 5/2 valve has a 25.0 mm2 effective area (Cv 1.40) and a max frequency of 4 cycles per second.
The 4M310 valve is internal piloted and requires no separate pilot line. It holds its last position by pilot pressure, not a spring. By default, the rod retracts when the AC220V coil is energised, but the valve can be repositioned to extend-when-energised.
