Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 150mm 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 SAIF80X150-08B
The AirTAC SAIF80X150-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve. Delivering a 2513N push force at 0.5 MPa and a 1.40 Cv flow rate, it is driven by a DC24V terminal entry coil consuming 3.0W. The integrated manifold uses O10xO6.5 PU tubing to connect the valve block to the cylinder, meaning the valve port (1/4) differs from the cylinder port (3/8).
Because the cylinder rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. By default, the piston rod retracts when the coil is energised, though this can be reconfigured to extend-when-energised by repositioning the valve. It switches itself from one coil signal, eliminating remote valves and reducing panel space for decentralized installations.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF80X150-08B Is Used
Decentralized Assembly Stations
Ideal for large machines where running valve tubing is costly, this self-contained unit operates from a single DC24V signal to reduce panel space.
High-Force Clamping
Delivers 2513N push force at 0.5 MPa for secure holding and clamping of heavy workpieces without needing a remote valve bank.
Space-Constrained Retrofits
The integrated 4M310 valve and manifold block eliminate external plumbing, making it perfect for upgrading tight machinery layouts.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08B the Right Choice?
Choose this 80mm bore when you need higher thrust than the 63mm bore (which offers 1559N push at 0.5 MPa), but less envelope than the 100mm option. A self-valved SAIF beats a separate cylinder plus remote valve in space-tight machines, as it requires only a single DC24V electrical signal to operate, minimizing plumbing across large machines. The 4M310 valve achieves a max frequency of 4 cycles per second.
For replacements, match the 80mm bore, 150mm stroke, 1/4 valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. Note that the 5/2 valve routes air but does not hold the load without live pressure; for position holding, consider the SAIL lock or BSAI clamp-lock cylinders. Since the stroke is 150mm, side-load is minimal, but always ensure proper guide alignment.
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 SAIF80X150-08B FAQ
At 0.5 MPa, the 80mm bore provides a 2513N push force and a 2268N pull force. The built-in 4M310-08 valve has a 1.40 Cv flow rate to handle the required air volume.
No, the SAIF80X150-08B features a built-in 4M310 5/2 solenoid valve. It switches itself from one DC24V coil signal. By factory default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
