Airtac SAIF Series Standard Cylinder with Valve SAIF100X450S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X450S-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm 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 SAIF100X450S-08A
The AirTAC SAIF100X450S-08A is a double-acting ISO 15552 profile cylinder integrating a 4M310-08 5/2 solenoid valve. It delivers a 1.40 Cv flow rate and operates on AC220V via a terminal electrical entry. The cylinder body rates to 1.0 MPa, but the practical working range for this valved unit is 0.15-0.8 MPa. It generates 3927N of push force at 0.5 MPa, making it suited for heavy loads.
The integrated manifold uses O10 x O6.5 PU tubing, and the valve port (1/4") differs from the cylinder port (1/2"). By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. It includes a magnet for CMSE reed and DMSE electronic sensors.

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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAIF100X450S-08A Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve bank, reducing tubing runs across large automated machinery.
Heavy Material Handling
Provides 3927N push force at 0.5 MPa for moving substantial payloads directly at the work point.
Space-Constrained Retrofits
Ideal for upgrading existing machinery where routing new valve exhaust tubing is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X450S-08A the Right Choice?
Choose this 100mm bore when 80mm (2513N push at 0.5 MPa) is insufficient for your load. The self-valved SAIF100X450S-08A eliminates remote plumbing, saving panel space for decentralized machine stations. For stroke lengths of 450mm, ensure external guides are used to prevent excessive side loading on the rod. Note that the 5/2 valve routes air but does not hold the load without live pressure; for true locking, consider the SAIL series. Replacement requires matching bore, 450mm stroke, 1/4" valve port, AC220V terminal coil, PT threads, and the -S magnet.
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 SAIF100X450S-08A FAQ
At 0.5 MPa operating pressure, the 100mm bore provides 3927N of push force and 3681N of pull force. The integrated 4M310-08 valve has a 1.40 Cv flow rate.
No, the 5/2 solenoid valve routes air but does not lock the load without live pressure. The factory setting retracts the rod when the AC220V coil is energised, but it can be repositioned to extend-when-energised.
