Airtac SAIF Series Standard Cylinder with Valve SAIF40X75-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X75-06B 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 SAIF40X75-06B
The AirTAC SAIF40X75-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers 628N of push force at 0.5 MPa. The valve provides a 14.0 mm2 effective area (Cv 0.78) and switches at up to 5 cycles per second. Because the cylinder body rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
This self-contained design eliminates the need for a separate remote valve, reducing plumbing and panel space for decentralized machine stations. The manifold connects to the cylinder via an O8 x O5 PU tube, distinguishing the 1/8" valve port from the cylinder's 1/4" port. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it.

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 SAIF40X75-06B Is Used
Decentralized Assembly Stations
Ideal for large machines where running individual valve tubing back to a main panel is costly, letting each station control its own 628N clamping action locally.
Space-Constrained Automation
The integrated 4M210 valve manifold saves valuable mounting space, fitting neatly into compact machinery where a separate valve bank would not fit.
Retrofit and Upgrades
Perfect for upgrading existing ISO 15552 cylinder footprints to self-switching decentralized control without extensive pneumatic rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X75-06B the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa and want to avoid running long air lines back to a central manifold. If your application requires less force, stepping down to a 32mm bore yields 402N; if you need more clamping power, a 50mm bore provides 982N. The SAIF40X75-06B excels in tight spaces where a separate valve would be cumbersome. Remember that the 5/2 valve routes air and the adjustable air cushion only decelerates near stroke ends, so this unit does not hold loads without live pressure. For position holding, consider a SAIL lock cylinder instead.
To replace this unit, match the 40mm bore, 75mm stroke, 1/8" PT valve port, DC24V terminal coil, and carbon steel rod. It lacks a magnet, so it cannot host CMSE or DMSE sensors without custom modification. At a 75mm stroke, side-load is minimal, but ensure proper alignment to maximize seal life.
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 SAIF40X75-06B FAQ
At 0.5 MPa, this 40mm bore cylinder generates 628N of push force and 528N of pull force. The integrated 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, it features a built-in 5/2 solenoid valve actuated by a DC24V terminal coil. By default, energizing the coil retracts the rod, but the valve can be repositioned to extend-when-energised. It switches itself from one coil signal, eliminating the need for external pneumatic tubing to a remote valve.
