Airtac SAIF Series Standard Cylinder with Valve SAIF80X900-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X900-08B 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 SAIF80X900-08B
The AirTAC SAIF80X900-08B is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by a DC24V terminal coil drawing 3.0 W, it activates in 0.05 s or less with IP65 protection. While the base cylinder rates to 1.0 MPa, the integrated valve limits the practical operating pressure to 0.15-0.8 MPa.
Generating 2268N of pull force at 0.5 MPa, this unit eliminates remote plumbing by routing air directly through a manifold block via PU tubing (O10 x O6.5). By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. It is a true extruded aluminum profile cylinder, dimensionally interchangeable per ISO 15552, not a tie-rod design.

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 SAIF80X900-08B Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, driving the 80mm bore directly from a DC24V signal without running long valve tubing back to a central panel.
Long-Stroke Handling
The 900mm stroke handles material push-off or transfer tasks, requiring an external guide to manage side loads on the extended carbon steel rod.
Space-Constrained Retrofits
Fits seamlessly where adding a separate 5/2 valve manifold is impossible, bundling the 4M310 valve and cylinder into one ISO 15552 envelope.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X900-08B the Right Choice?
Choose this 80mm bore when a 63mm bore (1402N pull at 0.5 MPa) lacks the force for your load, or step up from it if you need the 2513N push force. A self-valved SAIF excels over a separate cylinder plus remote valve in decentralized machine stations by slashing panel space and tubing runs. Because the 900mm stroke is long, use a side-load guide to prevent rod binding.
To replace this unit, match the 80mm bore, 900mm stroke, 4M310-08 valve, DC24V terminal coil, PT3/8 cylinder port, PT1/4 valve port, and standard carbon steel rod. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider a SAIL lock or BSAI clamp-lock cylinder.
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 SAIF80X900-08B FAQ
The 80mm bore generates 2268N of pull force and 2513N of push force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
No, it switches itself from one DC24V coil signal. The built-in 5/2 valve holds position via internal pilot, not a spring. By factory default, the rod retracts when energised, but you can reconfigure it to extend-when-energised by repositioning the valve.
