Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 50mm 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 SAIF50X50-08A
The AirTAC SAIF50X50-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a 982N push force at 0.5 MPa. The built-in valve provides a 16.0mm2 effective area (Cv 0.89) and operates at 5 cycles per second. Because the manifold block routes air directly via PU tubing (O8xO5), you save panel space by eliminating remote plumbing.
Although the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design is ideal for decentralized stations across large machines, requiring only a single electrical signal to drive the motion.

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 SAIF50X50-08A Is Used
Decentralized Machine Stations
Eliminates the need for a central valve manifold, allowing independent 50mm bore actuation at remote stations using only a single AC220V signal.
Compact Assembly Automation
The integrated 4M210-08 valve saves critical panel space, delivering 982N push force in tight machinery envelopes without external tubing runs.
Retrofit and Upgrades
Ideal for upgrading existing ISO 15552 setups where adding a remote valve bank is impractical, providing a self-contained PT1/4 ported actuation solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-08A the Right Choice?
Choose this 50mm bore when an application requires around 982N of push force at 0.5 MPa; step down to a 40mm bore (628N push) for lighter loads, or up to a 63mm bore (1559N push) if you need significantly more thrust. The SAIF50X50-08A is specified with a PT1/4 cylinder port, a 1/4" valve port, AC220V voltage, a terminal electrical entry, and no sensor magnet. It is dimensionally interchangeable per ISO 15552 mounting dimensions.
A self-valved unit like this beats a separate cylinder and remote valve in space-tight machines where running tubing is costly. Note that the 5/2 valve routes air but does not lock the load mechanically—without live pressure it cannot hold position. For load-holding requirements, consider the SAIL (lock) or BSAI (clamp-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 SAIF50X50-08A FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. The built-in 4M210-08 5/2 valve has an effective area of 16.0mm2 (Cv 0.89).
No separate remote valve is needed; the integrated 5/2 valve switches the cylinder directly from the AC220V terminal coil signal. By factory default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
