Airtac SAIF Series Standard Cylinder with Valve SAIF80X80S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X80S-08B 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-08B
The AirTAC SAIF80X80S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 s or less. The integrated valve manifold uses a PU tube (O10 x O6.5) to feed the cylinder, meaning the valve port (1/4) and cylinder port (3/8) serve distinct roles in the assembly. Because the cylinder body rates to 1.0 MPa but the 4M-series valve operates from 0.15 to 0.8 MPa, the practical working range for this valved unit is 0.15-0.8 MPa.
This 80mm bore generates 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. The factory setting retracts the piston rod when the coil is energised, though you can reposition the valve to extend-when-energised if your sequence demands it. By switching itself from one coil signal, it eliminates remote plumbing and saves panel space, making it highly suited for decentralized stations across large machines. The carbon steel rod and -S magnet option pair perfectly with AirTAC CMSE reed and DMSE electronic sensors for precise positioning feedback.

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.

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-08B Is Used
Decentralized Automation Cells
Ideal for large factory layouts where running separate valve tubing back to a central manifold is costly. The integrated 4M310 valve handles localized switching directly at the cylinder.
High-Force Clamping Jigs
Delivers 2513 N of push force at 0.5 MPa for securing heavy workpieces. The built-in DC24V coil ensures rapid 0.05 s actuation for tight machining cycles.
Space-Constrained Machinery
Saves valuable panel space by mounting the valve directly on the cylinder profile. The terminal electrical entry keeps wiring compact and organized.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X80S-08B the Right Choice?
Select this 80mm bore when your application requires substantial thrust (2513 N push at 0.5 MPa) but stepping up to a 100mm bore would be excessive, as the larger size delivers 3927 N at the same pressure. Conversely, if 1559 N is sufficient, dropping to a 63mm bore saves envelope space. The self-valved SAIF architecture beats a separate cylinder plus remote valve when you need to minimize tubing runs and wiring across a sprawling machine layout. Remember that the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, consider the SAIL lock or BSAI clamp-lock series. For stroke lengths of 300mm or more, add an external guide to prevent excessive side-load wear on the rod.
To replace this unit, match the 80mm bore, 80mm stroke, 4M310-08 valve, DC24V terminal coil, PT threaded ports, and the -S magnet. The integrated valve operates at up to 4 cycles per second, easily handling standard cycling rates within the 30-800 mm/s cylinder speed range.
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-08B FAQ
At 0.5 MPa, this 80mm bore double-acting cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
No, the 5/2 solenoid valve routes air to hold position only with live pressure; it is not a mechanical lock. By default, the rod retracts when the DC24V coil is energised, but the valve can be repositioned to extend-when-energised.
