Airtac SAIF Series Standard Cylinder with Valve SAIF80X700-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X700-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 700mm 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 SAIF80X700-08B
The AirTAC SAIF80X700-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific build uses a DC24V terminal coil drawing 3.0 W, actuating in 0.05 s or less with an IP65 rating. The integrated valve provides a 25.0 mm2 effective area (Cv 1.40) and cycles up to 4 times per second. Because the 4M310 valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it delivers 2513 N of push force.
This self-contained design eliminates the need for a separate remote valve, drastically reducing panel space and plumbing. The manifold connects to the cylinder via PU tubing (O10 x O6.5). Note that the valve port is 1/4" (code 08) while the cylinder port is 3/8". 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 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 SAIF80X700-08B Is Used
Decentralized Automation
Perfect for large machines with multiple stations, as the built-in valve eliminates long air lines back to a central manifold and requires only a DC24V signal to operate.
Heavy Workpiece Handling
The 80mm bore provides 2513 N of push force at 0.5 MPa, suitable for lifting and shifting heavy fixtures or clamping substantial components.
Retrofit & Upgrades
Ideal for upgrading existing ISO 15552 dimensional setups where adding external valve hardware is physically constrained or wiring a remote valve is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X700-08B the Right Choice?
Choose this 80mm bore when you need heavy thrust (2513 N push at 0.5 MPa) that a 63mm bore (1559 N) cannot provide, without jumping to the larger 100mm class. The integrated 4M310 valve means one DC24V terminal connection drives the actuator directly at the machine, making it ideal for decentralized stations where running separate valve tubing is costly. If your process drops pressure, remember the 5/2 valve routes air but does not lock the load; for true position holding under loss of pressure, consider an AirTAC SAIL lock cylinder instead.
For this 700mm stroke, ensure adequate side-load guidance to prevent rod binding, as the extended length increases leverage on the front cap. The exact replacement match is an 80mm bore, 700mm stroke, PT 3/8" cylinder port, with a 4M310-08 valve (1/4" valve port), DC24V voltage, PT thread, terminal entry, and no sensor 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 SAIF80X700-08B FAQ
At 0.5 MPa, this 80mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
No separate remote valve is needed; the unit switches itself from one DC24V coil signal. By factory default, the rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the integrated valve.
