Airtac SAIF Series Standard Cylinder with Valve SAIF80X225-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X225-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 225mm 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 SAIF80X225-08A
The AirTAC SAIF80X225-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. This integrated valve delivers a 25.0 mm2 effective area (Cv 1.40) and mounts directly via a manifold block using O10 x O6.5 PU tubing. Driven by an AC220V terminal connection coil drawing 3.5 VA, it achieves IP65 protection and a 0.05 s response time. The cylinder itself features a carbon steel rod and PT tapered threads.
Because the cylinder body rates to 1.0 MPa but the internal pilot 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 factory setting retracts the piston rod when the coil is energised, though you can reconfigure it to extend-when-energised simply by repositioning the valve. Generating 2513 N of push force at 0.5 MPa, it switches itself from one coil signal, eliminating remote plumbing and 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 SAIF80X225-08A Is Used
Decentralized Assembly Lines
Eliminates the need for a remote valve bank, allowing independent cylinder control directly at the station across sprawling factory layouts.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces during machining, without external pneumatic tubing.
Space-Constrained Machinery
The integrated manifold and valve block save valuable panel space, making it ideal for compact equipment where routing separate valve lines is costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X225-08A the Right Choice?
Choose this 80mm bore when your application requires substantial thrust, such as the 2513 N push force at 0.5 MPa, but stepping down to a 63mm bore offers 1559 N if you need a smaller footprint. Conversely, if you need the maximum 513 kgf at 1.0 MPa, the 100mm bore is the next step up. The self-valved SAIF80X225-08A beats a separate cylinder and remote valve setup by saving panel space and cutting tubing runs, particularly in decentralized layouts. It operates at 30-800 mm/s.
For replacements, match the 80mm bore, 225mm stroke, 4M310-08 valve port, AC220V voltage, terminal entry, PT thread, and standard carbon steel rod. Note that no magnet is specified, so CMSE or DMSE sensors cannot be used without modification. The 225mm stroke falls under the 300mm threshold, so extreme external side-load guides are less critical than on longer strokes. Keep in mind the 5/2 valve routes air but does not hold the load without live pressure; for true locking, consider the SAIL series.
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 SAIF80X225-08A FAQ
The 80mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a max frequency of 4 cycles/sec.
No, the integrated 4M310-08 5/2 solenoid valve switches the cylinder directly from one AC220V coil signal. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
