Airtac SAIF Series Standard Cylinder with Valve SAIF50X800-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X800-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm 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 SAIF50X800-06A
The AirTAC SAIF50X800-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This specific configuration pairs a 50mm bore with an 800mm stroke and a PT 1/8 valve port, yielding an effective flow coefficient of Cv 0.78. Driven by an AC220V terminal connection coil drawing 3.5 VA, it activates in 0.05 seconds. While the base cylinder rates to 1.0 MPa, the integrated valve limits the practical operating range to 0.15-0.8 MPa. It delivers 982N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend upon energising by repositioning the valve. Because the manifold uses an O8 x O5 PU tube to link the valve and cylinder, the 1/4 cylinder port differs from the 1/8 valve port. This self-contained design eliminates remote valves and extra tubing, making it highly effective for decentralized stations across large machines.

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)

|---|---|---|
| 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 SAIF50X800-06A Is Used
Decentralized Assembly Stations
Ideal for large manufacturing lines where routing individual valve tubing back to a central island is impractical, allowing each station to control itself.
Space-Constrained Diverter
Fits into tight machine envelopes where a separate valve manifold would occupy too much space, using the built-in 4M210 valve to drive the diverter directly.
Retrofit Actuation
Perfect for upgrading older pneumatic setups, eliminating the need to plumb long air lines to a remote valve by carrying the control signal via a single AC220V wire.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X800-06A the Right Choice?
Choose this 50mm bore when you need roughly 982N of push force at 0.5 MPa; stepping down to a 40mm bore drops the push force to 628N, while a 63mm bore increases it to 1559N. An 800mm stroke requires careful attention to side loads, so always use external guide rods to prevent rod binding and premature seal wear. The self-valved SAIF architecture beats a separate cylinder and remote valve when panel space is tight and running dedicated tubing is costly.
This specific model uses an AC220V terminal entry coil with PT threads and lacks a magnet. If you need position feedback, select the -S option to mount AirTAC CMSE reed or DMSE electronic sensors. Remember that the 5/2 valve routes air but does not lock the load; for true position holding, consider the SAIL lock series. To replace this unit, match the 50mm bore, 800mm stroke, 06 valve port, AC220V voltage, terminal entry, and PT thread.
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 SAIF50X800-06A FAQ
The 50mm bore generates 982N of push force and 825N of pull force at 0.5 MPa. The integrated 4M210-06 valve provides a 14.0 mm2 orifice with a Cv of 0.78.
It uses a 5/2 solenoid valve that holds its last position by pilot pressure, not a spring. The factory setting retracts the rod when the AC220V coil is energised, but you can reposition the valve to extend-when-energised. This eliminates the need for a separate remote valve.
