Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 800mm 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 SAIF40X800S-06A
The AirTAC SAIF40X800S-06A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve, offering an effective flow of 14.0 mm2 (Cv 0.78). It features a 40mm bore generating 628N push force at 0.5 MPa, paired with a carbon steel rod and an integrated magnet for CMSE reed and DMSE electronic sensors. Driven by an AC220V terminal coil drawing 3.5 VA, the unit activates in 0.05s 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 manifold connects the valve to the cylinder using O8xO5 PU tubing, meaning the 1/8" valve port and 1/4" cylinder port are distinct. Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised, enabling decentralized machine stations without remote plumbing.

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 SAIF40X800S-06A Is Used
Decentralized Assembly Lines
Eliminates the need for remote valve banks on large machines, driving the 800mm stroke directly from a single AC220V terminal signal.
Space-Constrained Machinery
The integrated 4M210 valve manifold saves critical panel space while delivering 628N of push force for compact operations.
Retrofit Automation
Ideal for upgrading older equipment where routing new pneumatic tubing to a central valve is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X800S-06A the Right Choice?
Choose this 40mm bore when you need 628N of push force at 0.5 MPa; if your application requires less force, the 32mm bore offers 402N, while the 50mm bore provides 982N. A self-valved SAIF cylinder is ideal for space-tight machines or retrofits where running separate valve tubing is costly, as one AC220V terminal signal drives the entire actuator. Ensure you match the exact replacement specifications: 40mm bore, 800mm stroke, 1/8" PT valve port, AC220V voltage, terminal entry, and an -S magnet.
With an 800mm stroke, you must account for potential side loads and implement external guide rails to prevent rod damage. Remember that the built-in 5/2 valve routes air but does not lock the load; for position holding under pressure loss, consider the SAIL lock series 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 SAIF40X800S-06A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 valve provides an effective flow area of 14.0 mm2 (Cv 0.78).
It uses an AC220V terminal coil (3.5 VA, IP65). By default, the piston retracts when energised, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
