Airtac SAIF Series Standard Cylinder with Valve SAIF50X400-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X400-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 400mm 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 SAIF50X400-06A
The AirTAC SAIF50X400-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This integrated manifold design eliminates the need for a remote valve, reducing panel space and PU tubing for decentralized machine stations. Driven by an AC220V terminal entry coil drawing 3.5 VA, it responds in 0.05s. The 4M210-06 valve provides a 14.0 mm2 effective area (Cv 0.78) and connects via an O8 x O5 PU tube to the cylinder.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. It generates 982N of push force and 825N of pull force at 0.5 MPa. Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your logic requires it. Note that the 5/2 valve routes air but does not lock the load.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X400-06A Is Used
Decentralized Automation
Eliminates remote valve banks on large machines by switching directly from a single AC220V terminal signal, minimizing plumbing across long distances.
Mid-Force Positioning
Provides 982N of push force at 0.5 MPa for mid-sized actuation tasks, offering a compact profile cylinder solution with integrated flow control.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 installations where adding external pneumatic tubing is costly or impractical due to space constraints.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X400-06A the Right Choice?
Choose this 50mm bore when you need around 982N push force at 0.5 MPa; stepping down to a 40mm bore yields 628N, while a 63mm bore provides 1559N. The self-valved SAIF architecture is ideal for space-tight machines where running separate valve tubing is costly, as one AC220V terminal connection drives the entire actuator. For this 400mm stroke, ensure adequate side-load guidance to prevent rod binding, as the air cushion only decelerates near stroke end and cannot hold the load without live pressure.
When ordering a replacement, verify the 50mm bore, 400mm stroke, 4M210-06 valve port code (1/8), PT thread type, AC220V voltage, terminal entry, and standard carbon steel rod. Because no magnet is specified, this unit will not trigger CMSE reed or DMSE electronic sensors.
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 SAIF50X400-06A FAQ
The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78). The 50mm bore cylinder generates 982N push and 825N pull force at 0.5 MPa, with a maximum thrust of 200 kgf at 1.0 MPa.
Yes, the factory setting retracts the rod when the AC220V coil is energised, but you can reconfigure the 5/2 valve position to extend-when-energised. The valve holds its position by pilot pressure, not a spring, but requires live pressure to function.
