Airtac SAIF Series Standard Cylinder with Valve SAIF100X50-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X50-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 50mm 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 SAIF100X50-08A
The AirTAC SAIF100X50-08A is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M310-08 5/2 solenoid valve, providing a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by an AC220V terminal-entry coil that consumes 3.5 VA and responds in 0.05 s, it delivers substantial thrust up to 3927 N at 0.5 MPa. While the bare cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa.
This decentralized assembly eliminates the need for a separate remote valve, drastically reducing panel space and plumbing. The manifold connects to the cylinder using O10 x O6.5 PU tubing, and the unit operates at speeds of 30-800 mm/s. From the factory, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve.

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)

| 0.5 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 SAIF100X50-08A Is Used
Decentralized Assembly Stations
Ideal for large automated lines where installing a central valve island is impractical, allowing local control of high-force clamping directly at the station.
High-Force Pressing
Provides robust linear thrust for pressing or forming tasks within tight machine envelopes, eliminating the need to plumb a separate high-flow valve.
Retrofit & Upgrades
Perfect for upgrading existing ISO 15552 cylinder footprints to self-switching units, minimizing rewiring and pneumatic tubing during machine modernization.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X50-08A the Right Choice?
Select this 100 mm bore model when an application demands high force in a compact footprint without the tubing complexity of a remote valve bank. If 3927 N of push force at 0.5 MPa exceeds your requirement, stepping down to an 80 mm bore yields 2513 N while saving envelope space. Conversely, this self-valved configuration shines in decentralized stations where running individual valve tubing back to a main panel is cost-prohibitive.
When specifying this exact replacement, confirm the 50 mm stroke, PT1/2 cylinder port, 4M310-08 valve port, AC220V voltage, PT thread, and terminal electrical entry. Note that the integrated 5/2 valve routes air but does not lock the load; for position holding under zero pressure, consider an AirTAC SAIL lock cylinder. The standard carbon steel rod is suitable for general industrial environments.
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 SAIF100X50-08A FAQ
At 0.5 MPa, this 100 mm 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) to handle the required air volume.
The built-in valve eliminates the need for a separate remote valve, saving panel space and simplifying decentralized installation. From the factory, the rod retracts when the AC220V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
