Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 150mm 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 SAIF40X150-06B
The AirTAC SAIF40X150-06B is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring an integrated 4M210-06 5/2 solenoid valve. This built-in valve provides an effective area of 14.0 mm2 (Cv 0.78) and routes air directly via a manifold block using O8 x O5 PU tubing, eliminating the need for a separate remote valve. Driven by a DC24V terminal coil drawing 3.0 W with IP65 protection and a 0.05 s response time, it switches itself from one coil signal. While the bare cylinder rates to 1.0 MPa, the practical operating range for this assembled unit is 0.15-0.8 MPa, matching the internal piloted valve limits.
In its factory setting, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. Delivering 628N of push force and 528N of pull at 0.5 MPa, this 40mm bore unit is tailored for decentralized installations across large machines. It uses a carbon steel rod and PT threaded ports, requiring no lubrication. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock variant.

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)

|---|---|---|
| 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 SAIF40X150-06B Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, minimizing panel space by driving the cylinder directly from its own integrated 4M210 valve.
Compact Assembly Lines
Perfect for space-tight machines where running separate valve tubing is costly, utilizing a direct DC24V terminal signal for 628N push force.
Wiring Retrofits
Suits facility upgrades where adding pneumatic plumbing is difficult, allowing a single electrical connection to control the 5/2 valve.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-06B the Right Choice?
Choose this SAIF40X150-06B when you need to reduce panel space and plumbing in decentralized stations, as the self-contained 4M210 valve eliminates long tubing runs to a remote manifold. If your application requires greater thrust, stepping up to the 50mm bore yields 982N of push force at 0.5 MPa. Conversely, if space is tight and force demands are lower, the 32mm bore provides 402N.
This specific configuration features a 150mm stroke, a 1/8" cylinder port, and a 1/8" valve port. It includes a DC24V terminal electrical entry and a standard carbon steel rod. When ordering a replacement, verify the bore, stroke, valve port size, coil voltage, entry type, and PT thread. Since the stroke is 150mm, standard guidance rules apply, but always ensure adequate mounting support for your specific load.
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 SAIF40X150-06B FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78).
No, the SAIF series features a built-in valve. By default, the rod retracts when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
