Airtac SAIF Series Standard Cylinder with Valve SAIF80X80S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X80S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 80mm 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 SAIF80X80S-08A
The AirTAC SAIF80X80S-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, offering a Cv of 1.40. Driven by an AC220V terminal coil that consumes 3.5 VA, it activates in 0.05s with IP65 protection. The integrated manifold uses PU tubing (O10xO6.5) to link the valve and cylinder, meaning the 1/4" valve port differs from the cylinder's 3/8" port. The -S magnet option supports position sensing with CMSE reed and DMSE electronic switches.
While the bare cylinder rates to 1.0 MPa, the practical working range for this valved assembly is 0.15-0.8 MPa. It delivers 2513N of push force at 0.5 MPa. By default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. This decentralized design eliminates remote plumbing, saving panel space across large machines.

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 SAIF80X80S-08A Is Used
Decentralized Stations
Ideal for large machines needing distributed actuation, driving the 80mm bore directly from one coil signal without a remote valve bank.
Space-Constrained Machinery
Saves valuable panel and footprint space by mounting the 4M310 valve directly to the cylinder via a compact manifold block.
Retrofit Automation
Perfect for upgrading older lines where running new pneumatic tubing from a central valve island to each cylinder is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X80S-08A the Right Choice?
Choose this 80mm bore when a 63mm bore (1559N push at 0.5 MPa) is insufficient, or step down if 50mm (982N) fits your load. The self-valved SAIF80X80S-08A beats a separate cylinder and remote valve by cutting tubing, wiring, and panel footprint. Remember, the 5/2 valve routes air but does not lock the load; for position holding, consider SAIL or BSAI. Replacement requires matching the 80mm bore, 80mm stroke, 1/4" 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 SAIF80X80S-08A FAQ
The 80mm bore provides 2513N push force at 0.5 MPa and 4523N at 0.9 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles/sec.
The AC220V coil drives the 5/2 valve, which by default retracts the rod when energised but can be reconfigured to extend by repositioning the valve. The valve routes air and does not lock the load; for position holding without pressure, use SAIL or BSAI.
