Airtac SAIF Series Standard Cylinder with Valve SAIF100X900S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X900S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 900mm 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 SAIF100X900S-08B
The AirTAC SAIF100X900S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Equipped with a DC24V terminal coil drawing 3.0 W, it delivers 3927N of push force at 0.5 MPa. The built-in valve offers a Cv of 1.40 and a 25.0 mm2 effective area, operating at a maximum frequency of 4 cycles per second. Because the valve is internally piloted, the practical working pressure for the assembled unit is 0.15-0.8 MPa, despite the cylinder body being rated for 1.0 MPa.
This 100mm bore unit includes a magnet for CMSE reed and DMSE electronic sensors. It uses a carbon steel piston rod and PT tapered threads. By default, the rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised by repositioning it. The manifold connects to the cylinder via PU tubing, and the 1/4" valve port is distinct from the cylinder's 1/2" port.

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 SAIF100X900S-08B Is Used
Decentralized Automation Cells
Ideal for large machine layouts where installing a central valve bank is impractical, allowing local control of heavy 100mm bore movements.
Long-Stroke Material Handling
Provides reliable 900mm actuation for heavy workpiece routing, benefiting from the integrated 4M310 valve's 4 cycle/sec speed.
Space-Constrained Retrofits
Drops into existing lines needing high push force (3927N at 0.5 MPa) without the wiring complexity of remote pneumatic controls.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X900S-08B the Right Choice?
Choose this self-valved SAIF100X900S-08B for decentralized stations where running remote valve tubing is costly or panel space is tight. It switches directly from one DC24V coil signal, eliminating separate plumbing. If your application requires less force, stepping down to a 63mm bore yields 1559N of push at 0.5 MPa. For higher flow needs, the 4M310-10 valve option offers a Cv of 1.68.
With a 900mm stroke, this cylinder requires external guide support to prevent side-load damage. The 5/2 valve routes air but does not lock the load; if you need true position holding under pressure loss, consider the SAIL lock or BSAI clamp-lock series. Replacement requires matching the 100mm bore, 900mm stroke, 1/4" valve port, DC24V terminal coil, PT thread, and -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 SAIF100X900S-08B FAQ
The 100mm bore generates 3927N of push force at 0.5 MPa and 5497N at 0.7 MPa. The built-in 4M310-08 valve provides a 25.0 mm2 effective area with a Cv of 1.40.
No, the integrated 5/2 valve controls the cylinder directly from a single DC24V terminal coil signal. Factory settings retract the rod when energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
