Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 450mm stroke and a built-in 4M310-10 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 SAIF80X450-10B
The AirTAC SAIF80X450-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve delivers a Cv of 1.68 and a 30.0 mm2 effective area, driving a robust 2513N push force at 0.5 MPa. Configured with a DC24V terminal coil drawing 3.0 W, it activates in 0.05 s or less. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the cylinder body itself rates to 1.0 MPa.
By routing air directly through a manifold block and O10 x O6.5 PU tubing, this unit eliminates remote plumbing and saves panel space. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. It switches itself from one coil signal, making it 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)
| 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 SAIF80X450-10B Is Used
Decentralized Automation
Perfect for large factory lines where running individual valve tubing back to a central manifold is costly and complex.
High-Force Clamping
Delivers 2513N push force at 0.5 MPa for heavy-duty machining and clamping tasks without needing external valves.
Machine Retrofitting
Ideal for upgrading older machines by installing self-contained actuation without modifying existing control panels.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-10B the Right Choice?
Choose this 80mm bore when you need more thrust than the 63mm version offers (1559N push at 0.5 MPa) but want to avoid the larger envelope of a 100mm cylinder. A self-valved SAIF80X450-10B beats a separate cylinder plus remote valve in space-tight machines, cutting tubing runs and wiring complexity. For replacements, match the 80mm bore, 450mm stroke, 3/8" valve port, PT3/8" cylinder port, DC24V voltage, terminal entry, and standard carbon steel rod. Note that no magnet is specified, so CMSE or DMSE sensors cannot be used without adding an -S piston.
With a 450mm stroke, the extended rod is susceptible to side loads. Ensure adequate guiding along the stroke length to prevent binding and premature seal wear. Remember that the built-in 5/2 valve routes air but does not lock the load; for position holding under pressure loss, consider a SAIL lock or BSAI clamp-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 SAIF80X450-10B FAQ
The 80mm bore generates a push force of 2513N and pull force of 2268N at 0.5 MPa. The built-in 4M310-10 valve provides a 30.0 mm2 effective area (Cv 1.68) with a maximum frequency of 4 cycles per second.
The 5/2 valve routes air but does not lock the load; it will not hold position without live pressure. The factory setting retracts the rod when the DC24V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve.
