Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06F is a genuine double-acting ISO 15552 cylinder with a Ø40mm 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 SAIF40X50S-06F
The AirTAC SAIF40X50S-06F is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve, delivering a 14.0 mm2 flow (Cv 0.78). Driven by a DC12V terminal entry coil drawing 3.0 W, it integrates switching directly onto the actuator. The cylinder body features a carbon steel piston rod and a magnetic piston (-S) for precise position detection using CMSE reed or DMSE electronic sensors.
While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. The manifold connects the valve to the cylinder via an O8xO5 PU tube, and the valve port (1/8") differs from the cylinder port (1/4"). Factory-set to retract when energized, the valve can be repositioned to extend on signal, offering self-contained decentralized control without remote plumbing.

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 (Ø40mm)

|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X50S-06F Is Used
Decentralized Assembly Stations
Eliminates the need for remote valve banks on large machines by switching locally via the DC12V signal, drastically reducing tubing runs.
Space-Constrained Machinery
The integrated 4M210 valve manifold saves valuable panel and footprint space while delivering 628N push force at 0.5 MPa.
Retrofit Automation Upgrades
Ideal for upgrading existing ISO 15552 fixtures where running new pneumatic tubing to a central manifold is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06F the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa, stepping up from the 32mm class (402N) for heavier loads, or down from the 50mm class (982N) to save space. The self-valved SAIF design eliminates separate remote valves and long tubing runs, making it ideal for decentralized stations where panel space is tight. It operates at 30-800 mm/s.
This model uses a DC12V terminal coil with PT tapered threads. If your application requires holding the load mechanically without live air pressure, note that the 5/2 valve and air cushions only route air and decelerate motion; they do not lock the rod. For secure clamping, consider the SAIL lock variant. When replacing, match the 40mm bore, 50mm stroke, 1/8" valve port, DC12V voltage, terminal entry, 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 SAIF40X50S-06F FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N push and 528N pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the SAIF40X50S-06F switches itself using the built-in 4M210 valve driven by a DC12V terminal coil. By factory default, the rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized.
