Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 50mm 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 SAIF50X50-06A
The AirTAC SAIF50X50-06A is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a Cv of 0.78. Driven by an AC220V terminal coil drawing 3.5 VA, it responds in 0.05 s and carries an IP65 rating. The integrated manifold connects to the cylinder via PU tubing (O8 x O5), meaning the valve port (1/8") differs from the cylinder port (1/4").
Because the cylinder body rates to 1.0 MPa but the internal valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers 982 N of push force at 0.5 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This self-switching design eliminates remote valves, saving panel space and tubing across decentralized 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF50X50-06A Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large machines by switching locally via the integrated 4M210 valve and a single AC220V signal.
Compact Assembly Tooling
Saves panel space and plumbing complexity in tight fixtures where delivering 982 N of push force at 0.5 MPa is necessary without external tubing.
Retrofit Automation
Ideal for upgrading existing ISO 15552 interchangeable setups where adding dedicated air lines for a separate valve would be too costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-06A the Right Choice?
Choose this 50mm bore when you need 982 N push force at 0.5 MPa; step down to a 40mm bore (628 N push) for lighter loads, or up to a 63mm bore (1559 N push) if you need more thrust. The self-valved SAIF architecture is ideal for space-tight machines where running separate valve tubing is costly, as one AC220V terminal connection drives the entire actuator. If your application requires holding a load without live pressure, note that the 5/2 valve routes air but does not lock the piston; consider an AirTAC SAIL lock cylinder instead.
To replace this unit, match the 50mm bore, 50mm stroke, PT1/8 valve port, AC220V voltage, terminal entry, and standard carbon steel rod. This version has no magnet; add an -S suffix if you require CMSE reed or DMSE electronic sensors for position feedback.
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 SAIF50X50-06A FAQ
At 0.5 MPa, this 50mm bore cylinder generates 982 N of push force and 825 N of pull force. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the integrated 5/2 solenoid valve switches the cylinder directly from an AC220V terminal coil signal. By factory default, the piston rod retracts when the coil is energised, but the valve can be repositioned to extend-when-energised if needed.
