Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 160mm 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 SAIF80X160S-08B
The AirTAC SAIF80X160S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. It integrates a DC24V terminal coil drawing 3.0 W, protected to IP65 with a 0.05 s activation time. The cylinder bore is 80 mm with a 160 mm stroke, generating 2513 N of push force at 0.5 MPa. Because the manifold uses PU tubing (O10 x O6.5) to bridge the valve and cylinder, the 1/4" valve port differs from the 3/8" cylinder port. The -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches.
Although the cylinder body rates to 1.0 MPa, the integrated 5/2 valve operates at 0.15-0.8 MPa, establishing the practical working range for this assembled unit. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised. By driving the cylinder directly from one coil signal, it eliminates remote plumbing and saves panel space 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)

| 0.5 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 SAIF80X160S-08B Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, switching the 80 mm bore locally from a DC24V signal without running long remote valve lines.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for heavy clamping or pressing tasks, utilizing the integrated 4M310-08 valve for rapid 4 cycle/sec operation.
Space-Tight Retrofits
Saves panel space by mounting the valve directly on the profile cylinder, perfect for retrofits where adding external manifolds is physically constrained.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08B the Right Choice?
Select this 80 mm bore when an application requires substantial thrust (2513 N push at 0.5 MPa) but stepping down to a 63 mm bore (1559 N) would underperform. The self-valved SAIF architecture is ideal for space-tight machines where running separate valve tubing is costly, as the 4M310 valve switches the cylinder locally. For loads requiring holding without live pressure, note that the 5/2 valve routes air but does not lock; consider an AirTAC SAIL lock cylinder instead. The carbon steel rod and PT tapered threads are standard. Replacement match: 80 mm bore, 160 mm stroke, 1/4" valve port, DC24V, terminal entry, PT thread, with -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 SAIF80X160S-08B FAQ
At 0.5 MPa, the 80 mm bore generates 2513 N push and 2268 N pull force. The built-in 4M310-08 5/2 valve has a 25.0 mm2 effective area (Cv 1.40) and a max frequency of 4 cycles/sec.
It uses a DC24V terminal coil (3.0 W, IP65). By default, the factory setting retracts the piston rod when energised, but you can reposition the valve to extend-when-energised. This eliminates the need for a separate remote valve.
