Airtac SAIF Series Standard Cylinder with Valve SAIF50X400S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X400S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 400mm 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 SAIF50X400S-06A
The AirTAC SAIF50X400S-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve, providing a Cv of 0.78 and a 14.0 mm2 effective area. Driven by an AC220V terminal connection coil drawing 3.5 VA, it activates in 0.05 s with an IP65 rating. Because the cylinder body rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. At 0.5 MPa it generates 982 N of push force and 825 N of pull force.
By default, the piston rod retracts when the coil is energised, though you can reconfigure it to extend-when-energised by repositioning the valve. The manifold connects to the cylinder via PU tubing (O8 x O5), and the valve port (1/8) differs from the cylinder port (1/4). This self-contained design eliminates remote valves and extra tubing, making it ideal for decentralized stations across large machines. The -S magnet option supports CMSE reed and DMSE electronic sensors.

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 SAIF50X400S-06A Is Used
Decentralized Automation Cells
Perfect for large machine layouts where running individual valve tubing back to a main panel is costly, as the integrated 5/2 valve handles switching locally.
Mid-Force Assembly Stations
Provides 982 N of push force at 0.5 MPa for pressing, clamping, or lifting tasks within space-constrained production lines.
Long-Stroke Material Handling
The 400mm stroke works well for pushing parts or diverting flow on conveyors, provided external guides manage the side load.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X400S-06A the Right Choice?
Choose this 50mm bore when you need around 982 N of push force at 0.5 MPa; stepping down to a 40mm bore drops the push force to 628 N, while stepping up to a 63mm bore increases it to 1559 N. A self-valved SAIF beats a separate cylinder and remote valve when panel space is tight and you want to minimize wiring across decentralized stations. Since the 5/2 valve routes air without a mechanical lock, do not rely on it or the air cushions to hold a load in place—use a SAIL lock or BSAI clamp-lock for position holding.
For this 400mm stroke, which exceeds 300mm, add an external guide to prevent excessive side loading and rod damage. The exact replacement must match the 50mm bore, 400mm stroke, 06 (1/8) valve port, AC220V terminal coil, PT thread, and -S magnet.
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 SAIF50X400S-06A FAQ
At 0.5 MPa, the 50mm bore generates 982 N of push force and 825 N of pull force. The built-in 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78 and a maximum frequency of 5 cycles per second.
No separate remote valve is needed. The integrated 5/2 valve switches the cylinder directly from the AC220V terminal coil signal. The factory default retracts the rod when energised, but you can reconfigure it to extend-when-energised by repositioning the valve.
