Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 450mm 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 SAIF80X450-08B
The AirTAC SAIF80X450-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, the valve provides a 25.0 mm2 effective area (Cv 1.40) and switches at up to 4 cycles per second. Because the cylinder body rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. At 0.5 MPa it generates 2513 N of push force and 2268 N of pull force.
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 to the cylinder via O10 x O6.5 PU tubing, and the valve port (1/4 inch) is distinct from the cylinder port (3/8 inch). This self-contained design eliminates remote plumbing, reduces panel space, 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 SAIF80X450-08B Is Used
Decentralized Automation Stations
Eliminates the need for a remote valve island on large machines by driving the cylinder directly from a single DC24V signal.
Space-Constrained Machinery
Integrating the 4M310 valve directly onto the profile body saves valuable panel space and reduces complex tubing runs.
High-Force Assembly Lines
Delivers 2513 N of push force at 0.5 MPa for heavy-duty clamping and pressing without external pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X450-08B the Right Choice?
Choose this 80 mm bore if your application requires high force, as stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N. Conversely, if you need even greater thrust, the 100 mm bore offers 3927 N at the same pressure. The 450 mm stroke is well within the 1500 mm standard maximum for this bore, but at this length you should incorporate a guide mechanism to prevent excessive side-loading on the rod.
A self-valved SAIF beats a separate cylinder and remote valve when wiring and tubing long distances is costly or space-prohibitive. To replace this unit, match the 80 mm bore, 450 mm stroke, 4M310-08 valve port, DC24V terminal coil, PT thread, and standard carbon steel rod. Note that the 5/2 valve routes air and does not hold the load without live pressure; for secure position holding, consider an AirTAC 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 SAIF80X450-08B FAQ
The cylinder provides 2513 N of push force and 2268 N of pull force at 0.5 MPa. The built-in 4M310-08 valve has a 25.0 mm2 effective area (Cv 1.40) and operates at a maximum frequency of 4 cycles per second.
No, the integrated 5/2 valve switches the cylinder directly from a DC24V terminal coil signal. By factory default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
