Airtac SAIF Series Standard Cylinder with Valve SAIF80X75-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X75-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 75mm 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 SAIF80X75-08B
The AirTAC SAIF80X75-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, offering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by a DC24V terminal coil drawing 3.0 W with IP65 protection, it responds in 0.05 s. While the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working pressure for this assembled unit. It delivers 2513 N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The manifold connects the valve to the cylinder using O10 x O6.5 PU tubing. Because it switches itself from one coil signal, it eliminates remote plumbing and is ideal for decentralized stations 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 SAIF80X75-08B Is Used
Decentralized Machine Stations
Eliminates the need for long tubing runs back to a central manifold, driving 2513 N push force directly at the workstation.
Space-Constrained Automation
Integrates the 4M310-08 valve onto the cylinder body to save valuable panel space in tightly packed production lines.
High-Force Component Handling
Provides robust 80mm bore thrust for moving heavy pallets or fixtures without requiring external valve infrastructure.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X75-08B the Right Choice?
Choose this 80mm bore when you need high force (2513 N push at 0.5 MPa) in a compact footprint, or step down to the 63mm bore (1559 N push at 0.5 MPa) if your load is lighter. A self-valved SAIF beats a separate cylinder plus remote valve by saving panel space, reducing wiring, and simplifying decentralized installations. The cylinder port is 3/8, while the valve port is 1/4. This configuration uses a DC24V terminal entry and PT thread. Note that the 5/2 valve routes air but does not hold the load without live pressure; for position holding, consider the SAIL lock cylinder.
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 SAIF80X75-08B FAQ
The 80mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
The built-in 5/2 valve allows the cylinder to switch itself from one DC24V coil signal, removing the need for a separate remote valve. The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
