Airtac SAIF Series Standard Cylinder with Valve SAIF80X900S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X900S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm 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 SAIF80X900S-08B
The AirTAC SAIF80X900S-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. Driven by a DC24V terminal entry coil drawing 3.0 W, it delivers a Cv of 1.40 and 2513N of push force at 0.5 MPa. The standard carbon steel rod and -S magnet enable precise position detection with CMSE reed or DMSE electronic sensors. Because the cylinder body rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
This self-switching unit eliminates the need for a remote valve bank, saving panel space and tubing across decentralized machine stations. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port (1/4") differs from the cylinder port (3/8"). Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence requires it.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAIF80X900S-08B Is Used
Decentralized Automation
Ideal for large machines where routing individual valve lines back to a central panel is costly, as the built-in valve handles switching directly at the station.
Long-Stroke Material Handling
The 900mm stroke and 2513N push force suit heavy push-off or diverter arms on conveyors, guided by the external structure to manage side loads.
Space-Constrained Retrofits
Drop-in solution for upgrading existing ISO 15552 fixtures where physical space prevents mounting a standalone solenoid valve nearby.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X900S-08B the Right Choice?
Choose this 80mm bore when you need substantial thrust (2513N push at 0.5 MPa) but want to avoid the plumbing of a separate valve. If your application requires less force, stepping down to a 63mm bore yields 1559N push at 0.5 MPa; stepping up to 100mm provides 3927N. The 900mm stroke demands a rigid guide to prevent side-loading damage, as the air cushion only decelerates the piston near stroke end and cannot hold the load without live pressure. For load-holding requirements, consider a SAIL lock cylinder instead.
This SKU specifies a DC24V terminal entry coil with PT threaded ports. When replacing, match the 80mm bore, 900mm stroke, 1/4" valve port, and the -S magnet option. The 4M310 valve achieves a maximum frequency of 4 cycles per second, making it suitable for high-speed actuation across large automated lines.
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 SAIF80X900S-08B FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. The integrated 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40), ensuring adequate airflow for the 900mm stroke.
Yes. The factory setting retracts the piston rod when the DC24V coil is energised, but you can reposition the 5/2 valve on the manifold block to extend-when-energised. This eliminates the need for a separate remote valve.
