Airtac SAIF Series Standard Cylinder with Valve SAIF100X125-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X125-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 125mm 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 SAIF100X125-08A
The AirTAC SAIF100X125-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by an AC220V coil with a terminal electrical entry, it consumes 3.5 VA and activates in 0.05 s. The integrated manifold uses PU tubing (O10 x O6.5) to bridge the valve and cylinder, meaning the 1/4" valve port and the 1/2" cylinder port are distinct entities. While the bare cylinder rates to 1.0 MPa, the practical operating range for this assembled valved unit is 0.15-0.8 MPa.
Generating up to 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa, this 100 mm bore actuator is designed for heavy loads. By default, the factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. Because it switches itself from a single 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 (Ø100mm)

| 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 SAIF100X125-08A Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve bank, allowing independent heavy-duty actuation at remote machine stations.
Space-Constrained Machinery
The integrated valve manifold saves critical panel and tubing space in compact automated equipment.
Retrofit Automation
Ideal for upgrading older machines where routing new pneumatic tubing back to a control cabinet is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X125-08A the Right Choice?
Choose this 100 mm bore SAIF when your application demands high thrust (3927 N push at 0.5 MPa); if you need less force, stepping down to the 80 mm bore yields 2513 N push at 0.5 MPa. The self-valved SAIF100X125-08A excels over a separate cylinder plus remote valve by saving panel space and reducing wiring complexity in decentralized layouts. It operates at 30-800 mm/s. Remember that the built-in 5/2 valve routes air but does not hold the load without live pressure; for true mechanical locking, select the SAIL series instead. When ordering a replacement, verify the 125 mm stroke, 1/4" valve port, AC220V terminal coil, PT threads, and standard carbon steel rod. As this stroke is under 300 mm, standard mounting handles the load without auxiliary guides.
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 SAIF100X125-08A FAQ
The 100 mm bore cylinder generates a push force of 3927 N at 0.5 MPa and 5497 N at 0.7 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40).
By factory default, the rod retracts when the AC220V coil is energised, but the valve can be repositioned to extend-when-energised. The 5/2 valve routes air and does not lock the load without live pressure; for load-holding, use the SAIL series.
