Airtac SAIF Series Standard Cylinder with Valve SAIF40X350-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X350-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 350mm 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 SAIF40X350-06A
The AirTAC SAIF40X350-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU utilizes a PT 1/8 valve port paired with an AC220V terminal electrical entry, drawing 3.5 VA. The built-in valve provides an effective area of 14.0 mm2 (Cv 0.78) and switches at a maximum frequency of 5 cycles per second. Because the manifold connects to the cylinder via O8 x O5 PU tubing, you eliminate remote plumbing and save panel space.
While the bare cylinder rates to 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa. In its factory setting, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The 40mm bore generates 628N of push force at 0.5 MPa, and the unit operates reliably at speeds of 30-800 mm/s.

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 SAIF40X350-06A Is Used
Decentralized Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by switching locally via the AC220V terminal connection.
Material Handling
Provides 628N push force at 0.5 MPa for diverting or lifting packages, utilizing the integrated 4M210-06 valve for rapid 5 cycle/sec actuation.
Space-Tight Retrofits
Fits into compact machinery where external valve islands cannot fit, using the O8 x O5 PU tube manifold to minimize the envelope.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X350-06A the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa; stepping down to a 32mm bore drops that to 402N, while a 50mm bore raises it to 982N. The self-valved SAIF design excels in decentralized installations where running individual valve tubing back to a central manifold is costly or space-prohibitive. A single AC220V terminal connection drives the entire actuator.
For this 350mm stroke length, adding a side-load guide is recommended to prevent rod damage and premature seal wear. Note that the 5/2 valve routes air and the end cushions only decelerate the stroke; neither holds the load mechanically without live pressure. For position locking, consider an AirTAC SAIL cylinder. Replacement requires matching the 40mm bore, 350mm stroke, PT1/8 valve port, AC220V voltage, terminal entry, PT thread, and no 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 SAIF40X350-06A FAQ
The 40mm bore generates 628N of push force and 528N of pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78).
No, the SAIF40X350-06A switches itself from one AC220V coil signal using the built-in 5/2 valve. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
