Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 250mm 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 SAIF100X250-08A
The AirTAC SAIF100X250-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides a Cv of 1.40 and routes air directly through a manifold block using O10 x O6.5 PU tubing, eliminating the need for separate remote valves and extensive plumbing. Equipped with an AC220V terminal entry coil drawing 3.5 VA, it responds in 0.05s with IP65 protection. While the cylinder body rates to 1.0 MPa, the practical SAIF operating range is 0.15-0.8 MPa due to the valve's pilot pressure limits.
Delivering substantial thrust, this 100mm bore unit generates 3927N push and 3681N pull forces at 0.5 MPa, peaking at 801 kgf at 1.0 MPa. By default, the factory valve setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The cylinder features a 25mm carbon steel rod, M20x1.5 rod thread, and 36mm adjustable air cushions at both ends to decelerate the load smoothly near stroke limits.

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 SAIF100X250-08A Is Used
Decentralized Automation
Ideal for large machines with distributed stations, eliminating long pneumatic tubing runs by switching the cylinder directly via the AC220V coil signal.
High-Force Clamping
Provides up to 801 kgf at 1.0 MPa for heavy-duty holding and clamping tasks, with a built-in 4M310 valve handling the necessary flow.
Retrofit Installations
Perfect for upgrading existing lines where adding a remote valve manifold is costly or space-prohibitive, offering a self-contained actuator solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X250-08A the Right Choice?
Choose this 100mm bore SAIF when your application requires high force in a decentralized layout. If you need less thrust, stepping down to the 80mm bore yields 2513N push at 0.5 MPa, but the SAIF100X250-08A maximizes output at 3927N without needing a separate valve island. The integrated 4M310-08 valve features a 1/4" port, which differs from the cylinder's 1/2" port, ensuring optimal flow control directly at the actuator. The AC220V terminal connection simplifies wiring for standard factory voltages.
When ordering a replacement, verify the 100mm bore, 250mm stroke, 4M310-08 valve, AC220V voltage, terminal entry, and PT thread type. Note that this model does not include a magnet (-S) for sensors; adding one enables CMSE reed or DMSE electronic solid-state switches. Because the stroke is 250mm, ensure adequate guide support to prevent excessive side loads on the rod. Remember that the 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider the SAIL lock or BSAI clamp-lock 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 SAIF100X250-08A FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At its maximum rated cylinder pressure of 1.0 MPa, it delivers up to 801 kgf, though the practical operating pressure for the valved assembly is 0.15-0.8 MPa.
No, the 4M310-08 5/2 valve is internally piloted and operates on 0.15-0.8 MPa. By default, the piston retracts when the AC220V coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
