Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06B

The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 125mm 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 SAIF40X125S-06B

The AirTAC SAIF40X125S-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, yielding a 14.0mm2 flow area (Cv 0.78). Driven by a DC24V terminal coil consuming 3.0W, it activates in 0.05s or less. The integrated manifold uses O8xO5 PU tubing, meaning the 1/8" valve port and 1/4" cylinder port are distinct. Although the cylinder body rates to 1.0MPa, the practical operating range is 0.15-0.8MPa due to the valve limits.

This 40mm bore generates 628N push and 528N pull at 0.5MPa. It includes a magnet for CMSE reed and DMSE electronic sensors. Factory-set to retract when energised, the valve can be repositioned to extend on signal. By switching itself from one coil signal, it eliminates remote valves, reducing tubing and panel space for 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.

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 SAIF40X125S-06B Is Used

factory

Decentralized Machine Stations

Eliminates the need for long air lines back to a central valve bank, driving local 40mm bore actuation directly from a DC24V signal.

precision_manufacturing

Compact Assembly Automation

Saves panel and footprint space by mounting the 5/2 valve directly on the profile body, ideal for tight cell layouts requiring 628N force.

settings_input_component

Retrofit & Upgrades

Simplifies machinery upgrades where running new pneumatic tubing is costly, using an integrated O8xO5 PU tube manifold for fast local switching.

Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X125S-06B the Right Choice?

Choose this self-valved SAIF40 unit when a decentralized machine station needs 628N push at 0.5MPa without the plumbing of a remote valve bank. If your application requires higher force, stepping up to the 50mm bore yields 982N push at 0.5MPa. Conversely, lighter duties can drop to the 32mm bore for 402N. The 125mm stroke is well within standard limits, but always verify guide clearances on longer strokes.

This model uses a DC24V terminal coil with PT threaded ports. Remember that the built-in 5/2 valve routes air but does not lock the load; for position holding under pressure loss, select an AirTAC SAIL lock cylinder. For replacements, match the 40mm bore, 125mm stroke, 1/8" valve port, DC24V terminal entry, PT threads, and the -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 SAIF40X125S-06B FAQ

The 40mm bore generates 628N push and 528N pull at 0.5MPa. The built-in 4M210-06 valve provides an effective area of 14.0mm2 (Cv 0.78) and operates at a maximum frequency of 5 cycles per second.

No, it switches itself from a single DC24V coil signal. By default, the factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
