Airtac SAIF Series Standard Cylinder with Valve SAIF40X500S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X500S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 500mm 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 SAIF40X500S-06B
The AirTAC SAIF40X500S-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU specifies a DC24V terminal coil consuming 3.0 W, paired with a PT1/8 cylinder port and a 1/8 inch valve port. Because the built-in valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembly, despite the bare cylinder rating of 1.0 MPa. The unit delivers 628N of push force at 0.5 MPa.
Equipped with a magnet for CMSE reed and DMSE electronic sensors, it supports position detection. The manifold links the valve to the cylinder using an O8xO5 PU tube, and by default, the piston rod retracts when the coil is energised, though you can reposition the valve to extend on signal. This self-contained design eliminates remote plumbing, saving panel space for decentralized machine stations.

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 SAIF40X500S-06B Is Used
Decentralized Stations
Ideal for large machines where running air lines to a remote valve bank is costly, this cylinder switches itself locally via the DC24V signal.
Long-Stroke Assembly
The 500mm stroke handles extended linear motion tasks in compact spaces while providing position feedback via CMSE/DMSE sensors.
Retrofit Automation
Perfect for upgrading existing ISO 15552 setups by eliminating extra plumbing and integrating the 4M210 valve directly onto the actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X500S-06B the Right Choice?
Choose this 40mm bore when 628N push force at 0.5 MPa is sufficient; step up to the 50mm bore if you need 982N, or down to 32mm for 402N. A self-valved SAIF excels over a separate cylinder and remote valve by cutting tubing runs and wiring complexity across decentralized stations. For this 500mm stroke, adding an external guide is recommended to manage side loads and prevent rod binding.
To replace this unit, match the 40mm bore, 500mm stroke, 4M210-06 valve with 1/8 inch port, DC24V voltage, terminal entry, PT threads, and the -S magnet. Remember the 5/2 valve routes air but does not lock the load; if unpowered holding is required, consider the SAIL lock cylinder instead.
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 SAIF40X500S-06B FAQ
The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78). The 40mm bore cylinder provides 628N push force and 528N pull force at 0.5 MPa.
No, the integrated 5/2 valve controls the cylinder directly from one coil signal. By factory default, the rod retracts when energised, but you can reconfigure the valve to extend-when-energised.
