Airtac SAIF Series Standard Cylinder with Valve SAIF80X200-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X200-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 200mm 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 SAIF80X200-08B
The AirTAC SAIF80X200-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific DC24V configuration uses a terminal electrical entry and delivers a Cv of 1.40 with a 25.0 mm2 effective orifice. Because the valve manifold mounts directly to the cylinder body using PU tubing, it eliminates the need for a separate remote valve, significantly reducing panel space and plumbing complexity for decentralized machine stations.
While the base cylinder itself is rated for 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, making 0.15-0.8 MPa the practical working range for this assembled unit. It delivers robust thrust, pushing with 2513 N at 0.5 MPa and 3518 N at 0.7 MPa. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence demands it.

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 SAIF80X200-08B Is Used
Decentralized Assembly Stations
Ideal for large machines where running individual valve lines is costly. The built-in 4M310 valve allows the cylinder to switch itself from a single DC24V signal.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces during machining operations without needing a separate valve manifold.
Space-Constrained Retrofits
Perfect for upgrading existing lines where panel space is tight. The manifold and PU tubing design removes the need to plumb a remote 5/2 valve.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X200-08B the Right Choice?
Select this 80 mm bore when your application requires higher force than the 63 mm class (which offers 1559 N push at 0.5 MPa) but does not need the full 3927 N push of the 100 mm version. The self-contained SAIF design excels over a standard cylinder plus remote valve when you need to minimize wiring and tubing runs across a large machine. The integrated 5/2 valve routes air to hold the rod in position pneumatically, but it is not a mechanical lock; if you need true load holding, consider the SAIL lock series instead.
When replacing this unit, verify the 200 mm stroke, 3/8 inch cylinder port, and the 1/4 inch valve port. This SKU specifies a DC24V coil drawing 3.0 W with a standard terminal entry and PT thread. Although the 200 mm stroke is within standard limits, always ensure adequate guiding for any stroke over 300 mm to prevent excessive side loading on the rod.
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 SAIF80X200-08B FAQ
The 80 mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The integrated 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
Yes, the built-in 5/2 valve handles all air routing, requiring only the DC24V terminal connection to operate. By factory default, energising the coil retracts the piston rod, but you can reconfigure the valve position to extend-when-energised if needed.
