Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 400mm stroke and a built-in 4M310-10 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 SAIF80X400S-10B
The AirTAC SAIF80X400S-10B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-10 5/2 solenoid valve. This integrated assembly delivers a Cv of 1.68 and generates 2513N of push force at 0.5MPa. Equipped with a DC24V terminal coil drawing 3.0W, it switches itself from one electrical signal, eliminating the need for remote plumbing. The carbon steel rod and -S magnet enable precise position detection with CMSE reed and DMSE electronic sensors.
Because the 4M310 valve operates at 0.15-0.8MPa, this defines the practical working range for the assembled unit, even though the cylinder body rates to 1.0MPa. The manifold connects to the cylinder via O10xO6.5 PU tubing, and the valve uses a 3/8in port while the cylinder port is PT3/8. Factory-set to retract when energised, the valve can be repositioned to extend on signal, offering flexible decentralized control for large machinery.

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 SAIF80X400S-10B Is Used
Decentralized Assembly Lines
Ideal for large automated machines where installing a remote valve island is impractical, saving panel space and simplifying wiring.
Heavy Material Handling
Provides robust 2513N push force for lifting and positioning heavy workpieces directly at the station without external plumbing.
Retrofit Automation
Perfect for upgrading existing machinery where routing new pneumatic tubing to a central manifold is costly or difficult.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-10B the Right Choice?
Choose this 80mm bore when a 63mm cylinder lacks thrust, as the 63mm bore yields 1559N push at 0.5MPa compared to 2513N here. Conversely, a 100mm bore provides 3927N if your application demands heavier loads. The SAIF80X400S-10B excels in space-tight machines where running separate valve tubing is costly, leveraging the DC24V terminal coil and IP65 protection for reliable decentralized stations. For stroke lengths of 400mm, ensure adequate guiding to prevent side-load damage.
Remember that the 5/2 valve routes air and is not a mechanical lock; the air cushion only decelerates near stroke end. For applications requiring true load-holding under zero pressure, consider the SAIL lock variant. To replace this unit, match the 80mm bore, 400mm stroke, 10 valve port, DC24V voltage, PT thread, terminal entry, 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 SAIF80X400S-10B FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5MPa. The built-in 4M310-10 valve has an effective area of 30.0mm2 (Cv 1.68) and a maximum frequency of 4 cycles per second.
The integrated 4M310 5/2 valve allows the cylinder to switch itself from a single DC24V signal, eliminating separate valves and tubing. Factory-set to retract when energised, it can be reconfigured to extend-when-energised by repositioning the valve.
