Airtac SAIF Series Standard Cylinder with Valve SAIF50X500S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X500S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 500mm 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 SAIF50X500S-06A
The AirTAC SAIF50X500S-06A is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, offering an effective flow of 14.0 mm2 (Cv 0.78). It features a 500 mm stroke, a carbon steel piston rod, and a magnet for CMSE reed and DMSE electronic sensors. Driven by an AC220V terminal connection coil drawing 3.5 VA, it activates in 0.05 s or less with IP65 protection. While the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, setting the practical working range for this assembly.
Generating 982 N of push force and 825 N of pull force at 0.5 MPa, this unit eliminates the need for a separate remote valve. The manifold connects the valve to the cylinder via O8 x O5 PU tubing, saving panel space and simplifying decentralized installation. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence requires 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 (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 SAIF50X500S-06A Is Used
Decentralized Assembly Stations
Eliminates the need for remote valve islands on large machines by driving the 500 mm stroke directly from a single AC220V signal.
Space-Constrained Machinery
The built-in 4M210 valve and short PU tubing save valuable panel space compared to a separate cylinder and remote valve setup.
Retrofit Automation
Ideal for upgrading older lines where routing new pneumatic tubing back to a central control cabinet is costly and complex.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X500S-06A the Right Choice?
Choose this self-valved SAIF50X500S-06A when you need decentralized control and want to avoid running long air lines back to a central manifold. At 0.5 MPa it provides 982 N push force; if your load requires more thrust, step up to the 63 mm bore which offers 1559 N push at the same pressure. The valve port is PT 1/8 (code 06) and the cylinder port is 1/4. Ensure your replacement matches the 50 mm bore, 500 mm stroke, AC220V voltage, terminal entry, PT threads, and the -S magnet option.
Because the stroke is 500 mm, pay attention to potential side loads and use a guide to prevent rod binding. The built-in 5/2 valve routes air to hold the cylinder in position pneumatically but does not mechanically lock the load; for true load-holding under pressure loss, consider an AirTAC SAIL lock cylinder.
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 SAIF50X500S-06A FAQ
At 0.5 MPa, the 50 mm bore provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes. The factory setting retracts the rod when the AC220V coil is energised, but you can reposition the 5/2 valve on the manifold block to make it extend-when-energised. No separate valve is needed.
