Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 175mm 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 SAIF40X175S-06A
The AirTAC SAIF40X175S-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal entry coil drawing 3.5 VA, it eliminates the need for a remote valve island. The cylinder body features a PT1/8 port, while the integrated valve utilizes a 1/8 inch connection via an O8xO5 PU tube manifold. Equipped with a magnet, it supports CMSE reed and DMSE electronic sensors for precise position feedback.
Although the bare cylinder rates to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa. It delivers 628N of push force and 528N of pull force at 0.5 MPa. By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. This decentralized design minimizes plumbing and panel space across large machines.

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 SAIF40X175S-06A Is Used
Decentralized Assembly Stations
Eliminates the need for long air tubing runs back to a central valve manifold, allowing independent control of multiple clamps via a single AC220V electrical signal.
Space-Constrained Machinery
The integrated 4M210 valve manifold saves valuable panel space and simplifies machine wiring in tight automation cells requiring 628N of push force.
Retrofit Automation Upgrades
Ideal for upgrading existing ISO 15552 fixtures where adding external pneumatic valves is difficult, providing a self-switching actuator with DMSE sensor compatibility.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X175S-06A the Right Choice?
Choose this 40mm bore when you need more thrust than a 32mm cylinder provides, but want to avoid the larger footprint of a 50mm unit. At 0.5 MPa, the 40mm bore yields 628N push force, stepping up from the 402N of a 32mm bore. The integrated 4M210-06 valve offers a 14.0 mm2 effective area (Cv 0.78) and handles up to 5 cycles per second. This self-contained assembly is ideal for space-tight machines where routing separate valve tubing is costly or impractical.
When replacing this unit, match the 40mm bore, 175mm stroke, PT1/8 cylinder port, 06 (1/8) valve port, AC220V terminal coil, and the -S magnet requirement. The built-in 5/2 valve routes air to switch the cylinder, but it does not lock or hold the load without live pressure; for true mechanical load-holding, consider an AirTAC SAIL lock cylinder instead. The standard carbon steel rod and adjustable air cushions handle dynamic loads reliably.
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 SAIF40X175S-06A FAQ
At 0.5 MPa operating pressure, this 40mm bore cylinder generates 628N of push force and 528N of pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the SAIF40X175S-06A switches itself directly from one AC220V coil signal. By factory default, energising the coil retracts the piston rod, but this can be reconfigured to extend-when-energised by repositioning the valve. Note that the 5/2 valve routes air but does not mechanically lock the load.
