Airtac SAIF Series Standard Cylinder with Valve SAIF100X300-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X300-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 300mm 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 SAIF100X300-08B
The AirTAC SAIF100X300-08B is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M310-08 5/2 solenoid valve. Delivering a Cv of 1.40 and a 25.0 mm2 effective area, this integrated unit eliminates the need for a remote valve bank, saving panel space and tubing. It is driven by a DC24V terminal connection coil consuming 3.0 W, featuring IP65 protection and a rapid 0.05 s activation time. While the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa.
Generating a robust 3927 N push force at 0.5 MPa, this 100 mm bore actuator is designed for heavy-duty decentralized stations. The factory setting retracts the piston rod when the coil is energised, but it can be reconfigured to extend-when-energised by simply repositioning the valve. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port (1/4") is intentionally smaller than the cylinder port (1/2") to optimize flow dynamics.

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 (Ø100mm)

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAIF100X300-08B Is Used
Decentralized Assembly Lines
Ideal for large machines with decentralized stations, eliminating long pneumatic tubing runs by controlling the actuator locally via a single DC24V signal.
Heavy Material Handling
Provides robust 3927 N push force at 0.5 MPa for moving heavy pallets or workpieces directly at the workstation without needing external valve manifolds.
Retrofit Automation
Perfect for machine upgrades where adding a new remote valve bank is costly, as the integrated 4M310-08 valve handles air routing directly on the cylinder.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X300-08B the Right Choice?
Choose this 100 mm bore model when maximum thrust is required, delivering 3927 N push at 0.5 MPa; if you need less force, stepping down to the 80 mm bore yields 2513 N push at 0.5 MPa. A self-valved SAIF excels over a separate cylinder and remote valve in space-constrained machines or decentralized layouts by cutting plumbing and wiring complexity. This configuration uses a DC24V terminal coil with PT thread. Remember that the built-in 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock series. At 300 mm stroke, ensure adequate guide support to prevent rod side-loading and premature seal wear.
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 SAIF100X300-08B FAQ
The 100 mm bore cylinder generates 3927 N push force and 3681 N pull force at 0.5 MPa. The built-in 4M310-08 valve provides a 25.0 mm2 effective area with a Cv of 1.40.
No, the integrated 4M310 5/2 valve switches the cylinder directly from a DC24V electrical signal. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
