Airtac SAIF Series Standard Cylinder with Valve SAIF50X300-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X300-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 300mm stroke and a built-in 4M210-06 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 SAIF50X300-06B
The AirTAC SAIF50X300-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers 982 N of push force at 0.5 MPa. The built-in valve provides an effective area of 14.0 mm2 (Cv 0.78) and switches up to 5 cycles per second. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
By default, the piston rod retracts when the coil is energised, though this can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via O8 x O5 PU tubing, meaning the 1/4" valve port and the 1/8" cylinder port serve distinct routing functions. This decentralized design eliminates the need for a separate remote valve, drastically reducing panel space and plumbing across large machines.

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 (Ø50mm)

|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X300-06B Is Used
Decentralized Conveyor Diverters
Eliminates remote valve plumbing on long conveyor lines by switching the 300 mm stroke diverter directly from a local DC24V signal.
Space-Constrained Machinery
Fits into compact machine cells where panel space is restricted, using the integrated 4M210 valve and O8 x O5 PU tubing to minimize footprint.
Retrofit Automation Upgrades
Ideal for upgrading older equipment where routing new air tubing to a central manifold is difficult, providing a self-contained actuation solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X300-06B the Right Choice?
Choose this 50 mm bore when you need 982 N push force at 0.5 MPa; step down to a 40 mm bore for 628 N, or up to a 63 mm bore for 1559 N if the load demands more thrust. The self-valved SAIF architecture is ideal for space-tight machines or retrofits where running pneumatic tubing back to a central manifold is costly, as it switches itself from one DC24V electrical signal. The 300 mm stroke requires attention to side-load conditions, so ensure adequate guide rails are used to prevent rod binding.
For load holding, remember the 5/2 valve routes air but does not lock the piston; if the machine requires true mechanical holding, consider the SAIL lock variant. This specific configuration uses a PT1/8 cylinder port, a PT1/8 valve port, a standard carbon steel rod, and no sensor magnet. To replace, match the 50 mm bore, 300 mm stroke, 4M210-06 valve, DC24V voltage, terminal entry, and PT thread.
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 SAIF50X300-06B FAQ
At 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the SAIF50X300-06B has a built-in 4M210 5/2 valve actuated by a DC24V terminal coil. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve, eliminating the need for external pneumatic plumbing.
