Airtac SAIF Series Standard Cylinder with Valve SAIF80X200S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X200S-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 SAIF80X200S-08B
The AirTAC SAIF80X200S-08B is a double-acting ISO 15552 profile cylinder that integrates a 4M310-08 5/2 solenoid valve directly via a manifold block and PU tubing (O10 x O6.5). Driven by a DC24V terminal coil consuming 3.0 W, it delivers 2513 N of push force at 0.5 MPa. The base cylinder rates to 1.0 MPa, but the practical operating range for this valved assembly is 0.15-0.8 MPa. A factory-installed magnet (-S) supports position sensing with AirTAC CMSE (reed) or DMSE (electronic) switches.
By embedding the valve, this unit switches itself from one coil signal, eliminating remote plumbing and making it ideal for decentralized machine stations. The 4M310-08 valve offers a 25.0 mm2 orifice (Cv 1.40) and a 4 cycle/sec max frequency. Factory set to retract the rod when energised, the valve can be repositioned to extend-when-energised. The cylinder features a carbon steel rod, PT3/8 cylinder ports, and a PT1/4 valve port.

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 SAIF80X200S-08B Is Used
Decentralized Assembly Stations
Ideal for large machines with multiple stations, using the built-in DC24V valve to cut tubing runs and simplify wiring across the factory floor.
Space-Constrained Automation
Delivers 2513 N push force at 0.5 MPa without a remote valve bank, saving valuable panel space and reducing overall machine footprint.
Retrofit Material Handling
Perfect for upgrading existing lines where routing new valve tubing is costly; the self-switching 5/2 valve manages the 200 mm stroke directly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X200S-08B the Right Choice?
Select this 80 mm bore when an application requires substantial thrust (2513 N push at 0.5 MPa) but stepping up to the 100 mm bore (3927 N push) is unnecessary. Conversely, a 63 mm bore provides 1559 N if payload is lighter. The self-contained SAIF architecture beats a separate cylinder plus remote valve in space-tight machines by consolidating wiring and tubing. For load-holding applications, note that the 5/2 valve routes air but does not lock the piston; an AirTAC SAIL lock or BSAI clamp-lock cylinder is required for dead-load holding.
When replacing this unit, match the 80 mm bore, 200 mm stroke, PT3/8 cylinder port, 4M310-08 valve (port code 08), DC24V voltage, terminal entry, PT thread, and the -S magnet. The 200 mm stroke is below the 1500 mm standard maximum, keeping the assembly compact while providing ample travel. Ensure side-load alignment is guided by external rails for optimal seal life.
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 SAIF80X200S-08B FAQ
The 80 mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The integrated 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) to drive the cylinder efficiently.
No, the built-in 4M310 5/2 valve switches the cylinder directly from the DC24V terminal coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
