Airtac SAIF Series Standard Cylinder with Valve SAIF40X200-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X200-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 200mm stroke and a built-in 4M210-08 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 SAIF40X200-08A
The AirTAC SAIF40X200-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve provides a Cv of 0.89 and routes air directly through a manifold block connected via PU tubing, eliminating the need for separate remote valves and extensive plumbing. Driven by an AC220V terminal connection coil consuming 3.5 VA, the unit responds in 0.05s with an IP65 rating. While the cylinder body itself rates to 1.0 MPa, the practical operating range for the assembled SAIF unit is 0.15-0.8 MPa.
This 40mm bore configuration generates 628N of push force and 528N of pull force at 0.5 MPa. Designed for decentralized machine stations, it switches itself from a single coil signal to reduce panel space and tubing runs. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your logic requires it. The cylinder uses a carbon steel rod and PT tapered threads for both the 1/4 inch cylinder port and 1/4 inch valve port.

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 SAIF40X200-08A Is Used
Decentralized Machine Stations
Ideal for large machines where routing air lines to a central panel is costly, this cylinder controls itself locally via the integrated 4M210 valve and AC220V terminal coil.
Compact Assembly Automation
Fits space-tight processing equipment by combining the actuator and 5/2 valve into one package, delivering 628N push force at 0.5 MPa without external valve hardware.
Retrofit & Upgrades
Perfect for upgrading existing ISO 15552 interchangeable setups where adding a separate valve manifold is impractical, utilizing the built-in valve's 0.89 Cv flow capacity.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X200-08A the Right Choice?
Choose this self-valved SAIF40X200-08A when a decentralized station requires moderate thrust (628N push at 0.5 MPa) without the wiring and tubing overhead of a remote valve bank. If your application demands higher force, stepping up to the 50mm bore yields 982N of push force at 0.5 MPa; conversely, scaling down to a 32mm bore drops the output to 402N. Because the stroke is 200mm, ensure adequate guiding to prevent excessive side-loading on the rod. This assembly does not hold its load without live pressure, as the 5/2 valve routes air rather than locking it. For true position holding, consider the SAIL series. To replace this unit, match the 40mm bore, 200mm stroke, 08 (1/4 inch) valve port, AC220V voltage, terminal entry, PT threads, and standard carbon steel rod.
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 SAIF40X200-08A FAQ
At 0.5 MPa operating pressure, the 40mm bore generates 628N of push force and 528N of pull force. The maximum thrust reaches 128 kgf at 1.0 MPa, though the practical working range for the valved assembly is 0.15-0.8 MPa.
No, the SAIF40X200-08A features a built-in 4M210-08 5/2 solenoid valve. Driven by an AC220V terminal coil, it switches directly from one electrical signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
