Airtac SAIF Series Standard Cylinder with Valve SAIF80X80-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X80-08A 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 SAIF80X80-08A
The AirTAC SAIF80X80-08A is a double-acting ISO 15552 profile cylinder fitted with a built-in 4M310-08 5/2 solenoid valve. Delivering a Cv of 1.40 and a 25.0 mm2 effective area, this integrated manifold switches itself from a single AC220V terminal coil signal. The assembly operates within a 0.15-0.8 MPa pressure range, as the valve pilots internally at a lower ceiling than the 1.0 MPa cylinder body rating. At 0.5 MPa it generates 2513 N of push force and 2268 N of pull force.
By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your cycle logic requires it. The manifold links the valve to the cylinder using O10 x O6.5 PU tubing, meaning the 1/4" valve port and the 3/8" cylinder port are distinct pathways that must not be confused. This decentralized architecture eliminates remote plumbing, saves panel space, and removes the need for a separate valve island on 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)

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 SAIF80X80-08A Is Used
Decentralized Assembly Stations
Ideal for large manufacturing lines where running individual valve tubing back to a central island is costly. The integrated 4M310 valve lets each 80mm cylinder operate independently from a single AC220V signal.
Space-Constrained Machinery
Delivers 2513 N of thrust at 0.5 MPa in a compact ISO 15552 profile envelope. The built-in manifold removes the need for external valve mounting hardware, saving critical machine footprint.
Retrofit and Upgrades
Perfect for upgrading existing pneumatic setups. The terminal electrical entry and self-contained 5/2 valve simplify wiring and plumbing during machine modernization projects.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X80-08A the Right Choice?
Choose this 80mm bore when 50mm (982 N push at 0.5 MPa) is insufficient but you want to avoid stepping up to a 100mm bore (3927 N at 0.5 MPa) that demands more air volume. The self-valved SAIF80X80-08A beats a separate cylinder plus remote valve in space-tight machines or decentralized stations, as it requires only one electrical signal and a main air supply. Select this AC220V terminal entry configuration for standard factory voltages; ensure your control circuit can handle the 3.5 VA coil draw and 0.05 s activation time.
When specifying replacements, verify the 80mm bore, 80mm stroke, 1/4" valve port, 3/8" cylinder port, AC220V voltage, terminal entry, PT thread, and absence of a magnet (-S). Note that the 5/2 valve routes air but does not lock the load mechanically; if you need true position holding without live pressure, consider the AirTAC SAIL lock series instead. The carbon steel rod and adjustable air cushions handle standard deceleration, but always guide external loads to prevent rod side-loading.
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 SAIF80X80-08A FAQ
The 80mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa, reaching up to 4523 N push at 0.9 MPa. The built-in 4M310-08 5/2 valve provides a 25.0 mm2 effective area (Cv 1.40) with a maximum frequency of 4 cycles per second.
No, the 5/2 solenoid valve routes air but does not mechanically lock the piston. The factory setting retracts the rod when the AC220V coil is energised, but it can be reconfigured to extend-when-energised. For true position holding without live pressure, use a SAIL lock cylinder.
