Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-06F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-06F is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 75mm 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 SAIF40X75S-06F
The AirTAC SAIF40X75S-06F is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a Cv of 0.78 and 628N of push force at 0.5 MPa. It features a carbon steel piston rod and a -S magnet for position sensing with CMSE reed and DMSE electronic switches. Driven by a DC12V terminal entry coil consuming 3.0 W, the integrated design eliminates remote plumbing. The manifold connects the valve to the PT1/8 cylinder ports via O8xO5 PU tubing, creating a self-switching actuator ideal for decentralized machine stations.
While the bare cylinder rates to 1.0 MPa, the internal pilot valve operates at 0.15-0.8 MPa, making 0.15-0.8 MPa the practical working range for this assembled unit. By factory default, the piston rod retracts when the coil is energized, but you can reposition the valve to extend-when-energised. The assembly holds a 5/2 position via pilot pressure, not a spring, and the adjustable air cushions only decelerate the rod near stroke ends without locking the load.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF40X75S-06F Is Used
Decentralized Machine Stations
Ideal for large machines with scattered actuators, letting one DC12V signal drive the cylinder directly without running long valve tubing back to a central panel.
Compact Assembly Lines
Fits into tight equipment envelopes where space is premium, using the built-in 4M210 valve and O8xO5 PU manifold to eliminate external valve plumbing.
Sensor-Equipped Positioning
The included -S magnet works with DMSE solid-state and CMSE reed switches to confirm mid-stroke or end-of-travel positions for automated sequencing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-06F the Right Choice?
Choose this 40mm bore when a 32mm cylinder lacks thrust (delivering only 402N push at 0.5 MPa) or when a 50mm unit is oversized (offering 982N). The SAIF40X75S-06F excels over a separate cylinder and remote valve by cutting panel space, wiring, and tubing. To replace it, match the 40mm bore, 75mm stroke, 1/8 PT cylinder port, 06 (1/8) valve port, DC12V voltage, terminal entry, and -S magnet. If your machine requires dead-stop load holding, note that the 5/2 valve routes air but does not lock; select an AirTAC SAIL lock cylinder instead. With a 75mm stroke, side-load is minimal, but always guide external weights.
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 SAIF40X75S-06F FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 5/2 valve provides an effective area of 14.0 mm2 (Cv 0.78) with a maximum frequency of 5 cycles per second.
Yes. The factory setting retracts the rod when the DC12V coil is energised, but you can reposition the 5/2 valve on the manifold block to extend-when-energised. It holds position via pilot pressure, so no separate remote valve is needed.
