Airtac SAIF Series Standard Cylinder with Valve SAIF100X400S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X400S-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 400mm 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 SAIF100X400S-08A
The AirTAC SAIF100X400S-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. Driven by an AC220V terminal coil drawing 3.5 VA, it eliminates the need for a separate remote valve. The integrated manifold connects to the cylinder via PU tubing (O10 x O6.5), making it ideal for decentralized stations across large machines. It includes a magnet for CMSE reed and DMSE electronic sensors.
Although the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads efficiently. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend on signal. The 5/2 valve holds position via pilot pressure, not a mechanical lock.

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 SAIF100X400S-08A Is Used
Decentralized Automation
Perfect for large-scale production lines where running individual valve tubing back to a main panel is costly and complex.
Heavy Material Handling
Provides robust 3927 N push force at 0.5 MPa for lifting and shifting heavy workpieces directly at the workstation.
Retrofit & Upgrades
Ideal for upgrading existing ISO 15552 machinery setups where physical panel space for external valves is unavailable.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X400S-08A the Right Choice?
Choose this 100mm bore when you need maximum thrust, such as 3927 N push at 0.5 MPa; stepping down to an 80mm bore drops that output to 2513 N. The self-contained SAIF design beats a traditional cylinder plus remote valve setup by drastically cutting plumbing and panel space. A 400mm stroke demands attention to side loads, so ensure adequate guide rails to prevent rod damage. This specific SKU features a PT1/4 cylinder port, a 1/4 inch valve port, AC220V voltage, terminal entry, and a magnet for position sensing. For exact load-holding requirements, note that neither the 5/2 valve nor the air cushions act as a brake; consider an AirTAC SAIL lock cylinder instead.
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 SAIF100X400S-08A FAQ
At 0.5 MPa, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. The integrated 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40).
No, it has a built-in 4M310 valve actuated by an AC220V terminal coil. By factory default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
