Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 50mm 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 SAIF80X50S-10B
The AirTAC SAIF80X50S-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific build uses a DC24V terminal coil drawing 3.0 W, paired with a PT3/8 cylinder port and a 3/8 valve port. The integrated valve offers a Cv of 1.68 and a 30.0 mm2 effective area, driving the 80mm bore to deliver 2513N of push force at 0.5 MPa. Because the valve manifold uses O10 x O6.5 PU tubing, the valve port differs from the cylinder port and should not be confused with it.
While the cylinder body rates to 1.0 MPa, the built-in valve operates at 0.15-0.8 MPa, making 0.15-0.8 MPa the practical working range for this assembled unit. By default, the factory setting retracts the piston rod when the coil is energised; this can be reconfigured to extend-when-energised simply by repositioning the valve. The -S magnet option enables position sensing with AirTAC CMSE reed and DMSE electronic sensors. This self-switching design eliminates remote valves, reducing panel space and tubing for decentralized machine stations.

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)

| 0.7 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 SAIF80X50S-10B Is Used
Decentralized Assembly Stations
Ideal for large machines with multiple stations, eliminating the need for a central valve island and long tubing runs by controlling the cylinder directly at the point of use.
High-Force Clamping Fixtures
Provides robust 2513N push force at 0.5 MPa for securing heavy workpieces, utilizing the integrated 4M310-10 valve for rapid 4Hz actuation without external plumbing.
Retrofitted Conveyor Diverters
Perfect for upgrading existing conveyor lines where adding a remote valve manifold is impractical, offering a self-contained DC24V terminal-driven diverter solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10B the Right Choice?
Choose this 80mm bore SAIF when your application requires high thrust (2513N push at 0.5 MPa) and localized control. If you need less force, stepping down to the 63mm bore yields 1559N push at 0.5 MPa; stepping up to the 100mm bore provides 3927N. The SAIF80X50S-10B excels in decentralized installations where running separate valve tubing is costly, as one DC24V terminal signal directly drives the cylinder. The 50mm stroke is short and well within standard limits, requiring no side-load guide caveats.
For replacements, match the 80mm bore, 50mm stroke, 3/8 valve port, DC24V voltage, terminal entry, PT thread, and -S magnet. Remember that the 5/2 valve routes air but does not hold the load without live pressure; it is not a lock. For pneumatic locking applications, consider the SAIL series instead. The 4M310 valve allows a maximum frequency of 4 cycles per second.
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 SAIF80X50S-10B FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5 MPa. The built-in 4M310-10 valve has an effective area of 30.0 mm2 (Cv 1.68) and supports up to 4 cycles per second.
The 5/2 valve routes air but does not lock the load without live pressure. By factory default, the rod retracts when the DC24V coil is energised; this can be reconfigured to extend-when-energised by repositioning the valve.
