Airtac SAIF Series Standard Cylinder with Valve SAIF80X800-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X800-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 800mm 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 SAIF80X800-08B
The AirTAC SAIF80X800-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal entry coil drawing 3.0 W, it responds in 0.05 s and is rated IP65. The cylinder body rates to 1.0 MPa, but because the integrated valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 MPa. At 0.5 MPa it provides 2513 N push and 2268 N pull force.
By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. 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"). Switching itself from one coil signal, it eliminates remote plumbing and panel space, making it highly effective for decentralized installations 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)

|---|---|---|
| 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 SAIF80X800-08B Is Used
Decentralized Automation
Ideal for large machines with multiple stations, using the built-in valve to cut panel space and eliminate long tubing runs back to a central manifold.
Material Handling
Provides robust 2513 N push force at 0.5 MPa for diverting or lifting heavy products on 800 mm stroke conveyors without external valve plumbing.
Retrofit Upgrades
Simplifies machine upgrades where adding a new remote valve island is too costly, as this cylinder switches directly from a single DC24V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X800-08B the Right Choice?
Choose this 80 mm bore when you need heavy thrust (2268 N pull at 0.5 MPa) that exceeds the 50 mm bore class (825 N pull), without stepping up to the 100 mm size. A self-valved SAIF80X800-08B beats pairing a separate cylinder and remote valve when decentralization, wiring simplicity, and minimizing tubing runs are priorities. The 800 mm stroke falls within the 1500 mm standard limit, but at this length a side-load guide is recommended to prevent rod damage. This SKU specifies a DC24V terminal coil, PT thread, and no magnet.
For position sensing, adding the -S magnet option allows the use of AirTAC CMSE (reed) or DMSE (electronic) switches in the sensor grooves. Note that the 5/2 valve routes air but does not lock the load; if static holding is required, refer to the SAIL lock series. Replacement requires matching bore, stroke, valve port, coil voltage, entry, and thread.
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 SAIF80X800-08B FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The integrated 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, the integrated 4M310 valve switches the cylinder directly from a DC24V terminal coil signal. Factory set to retract when energised, the valve can be repositioned to extend-when-energised, offering flexible control without remote plumbing.
