Airtac SAIF Series Standard Cylinder with Valve SAIF40X500-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X500-06A 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 SAIF40X500-06A
The AirTAC SAIF40X500-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it eliminates the need for a separate remote valve. The integrated valve provides a 14.0 mm2 effective area (Cv 0.78) and switches up to 5 cycles per second, responding in 0.05 s. Because the valve manifold mounts directly using an O8 x O5 PU tube, it drastically reduces plumbing and panel space for decentralized machine stations.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa, yielding a push force of 628 N at 0.5 MPa. The cylinder features a 1/8 port thread and a 16 mm carbon steel rod. From the factory, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. Note that the 5/2 valve routes air and does not lock the load; use SAIL for mechanical holding.

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 SAIF40X500-06A Is Used
Decentralized Conveyor Diverters
Ideal for routing packages on long conveyor lines where running individual air tubes back to a main valve bank is inefficient.
Space-Constrained Machinery
Fits into compact automated equipment by mounting the 5/2 valve directly on the cylinder, freeing up valuable electrical cabinet space.
Retrofit Automation Stations
Simplifies upgrades to existing production lines by combining the actuator and valve into a single AC220V powered assembly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X500-06A the Right Choice?
Choose this 40 mm bore when you need 628 N of push force at 0.5 MPa; stepping down to a 32 mm bore drops the output to 402 N, while a 50 mm bore raises it to 982 N. The self-contained SAIF design excels over a standard SAI cylinder plus remote valve when wiring and air tubing to a central panel are costly or impractical. This specific SKU uses an AC220V terminal connection and a PT 1/8 valve port. To replace this unit, match the 500 mm stroke, 1/8 cylinder port, 4M210-06 valve, AC220V voltage, terminal entry, and standard carbon steel rod.
Because the 500 mm stroke exceeds 300 mm, ensure adequate guiding to prevent excessive side loads on the rod seals. Operating speed ranges from 30-800 mm/s. The unit is dimensionally interchangeable per ISO 15552, though the valve manifold adds to the overall envelope.
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 SAIF40X500-06A FAQ
At 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. The integrated 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78).
No, it has a built-in 4M210 5/2 valve. By default, energising the AC220V coil retracts the rod, but the valve can be repositioned to extend-when-energised. It operates on 0.15-0.8 MPa and holds position via pilot pressure, not a mechanical lock.
