Airtac SAIF Series Standard Cylinder with Valve SAIF40X350-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X350-06B 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 SAIF40X350-06B
The AirTAC SAIF40X350-06B is a double-acting ISO 15552 profile cylinder with an integrated 4M210-06 5/2 solenoid valve, providing a Cv of 0.78 and a 14.0 mm2 orifice. Driven by a DC24V terminal coil consuming 3.0 W, it activates in 0.05 s or less with IP65 protection. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The 40 mm bore generates 628 N of push force at 0.5 MPa.
By mounting the valve directly via a manifold block and O8 x O5 PU tubing, this unit switches itself from one coil signal, eliminating remote plumbing and panel space. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The valve port is 1/8 inch (code 06) while the cylinder port is 1/4 inch, and neither the 5/2 valve nor the adjustable air cushions will hold a load without live pressure.

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 SAIF40X350-06B Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve island on large machines by processing the DC24V signal and compressed air locally at the station.
Compact Clamping Fixtures
Saves panel space by integrating the 4M210 valve directly onto the cylinder, providing 628 N of clamping force in tight machine envelopes.
Retrofit Automation
Ideal for upgrading older machines where routing new pneumatic tubing back to a remote valve bank is structurally prohibitive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X350-06B the Right Choice?
Choose this 40 mm bore if your application requires less force than the 50 mm bore (982 N push at 0.5 MPa) but more than the 32 mm option (402 N). The self-valved SAIF40X350-06B excels in decentralized stations where running separate valve tubing is costly, offering a clean single-wire DC24V terminal connection. If you need true load holding on a vertical lift, note that this 5/2 valve routes air but does not lock; consider the SAIL series for mechanical locking instead.
With a 350 mm stroke, ensure you provide adequate side-load guidance to prevent rod binding, as the air cushions only decelerate the piston near the stroke ends. When replacing this unit, match the 40 mm bore, 350 mm stroke, 1/8 inch valve port, DC24V voltage, PT thread, terminal entry, and standard carbon steel rod. No magnet is specified, so CMSE reed or DMSE electronic sensors cannot be used without adding the -S option.
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 SAIF40X350-06B FAQ
The 40 mm bore generates 628 N of push force and 528 N of pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the integrated 5/2 valve switches the cylinder directly from the DC24V terminal coil signal. By default the rod retracts when energised, but you can reposition the valve to extend-when-energised. The unit operates at 0.15-0.8 MPa.
