Airtac SAIF Series Standard Cylinder with Valve SAIF80X900-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X900-08A 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 SAIF80X900-08A
The AirTAC SAIF80X900-08A is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve. Featuring a 1.40 Cv flow coefficient, this self-switching unit eliminates remote plumbing. Driven by an AC220V terminal entry coil drawing 3.5 VA, it activates in 0.05s. The integrated valve operates at 0.15-0.8 MPa, setting the practical working range for the assembly, while the ISO 15552 interchangeable body delivers 2513N push force at 0.5 MPa.
Factory set to retract the rod when the coil energises, you can reposition the valve to extend-when-energised if needed. The manifold connects to the 3/8 inch cylinder port via O10 x O6.5 PU tubing, while the valve uses a 1/4 inch port. This decentralized design requires only one electrical signal to control movement, drastically reducing panel space and tubing runs across large machines.

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 SAIF80X900-08A Is Used
Decentralized Automation
Ideal for large machines with multiple stations, eliminating long valve tubing runs by mounting the 5/2 valve directly on the cylinder.
Long-Stroke Handling
Provides 2513N push force over a 900mm stroke for moving heavy pallets, provided an external guide handles the side-load.
Retrofit Upgrades
Drops into existing ISO 15552 footprints to add self-valving capability, cutting pneumatic plumbing complexity during machine upgrades.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X900-08A the Right Choice?
Choose this 80mm bore when a 63mm cylinder (1559N push at 0.5 MPa) lacks thrust, but a 100mm bore (3927N) is excessive. The 900mm stroke demands a guide to prevent rod side-loading and extend bearing life. Select this AC220V terminal coil model for standard mains-powered control panels. Because the built-in 5/2 valve routes air rather than mechanically locking, use an external SAIL lock or BSAI clamp-lock if the load must hold position without live pressure. Replacement requires matching the 80mm bore, 900mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, PT thread, and no magnet (-S).
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 SAIF80X900-08A FAQ
At 0.5 MPa, the 80mm bore provides 2513N of push force and 2268N of pull force. The integrated 4M310-08 valve has a 1.40 Cv flow coefficient to handle the required air volume.
No, the SAIF80X900-08A includes a built-in 4M310-08 5/2 valve. It switches directly from the AC220V terminal coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
