Airtac SAIF Series Standard Cylinder with Valve SAIF50X80-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X80-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 80mm 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 SAIF50X80-06A
The AirTAC SAIF50X80-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve, offering a Cv of 0.78. Driven by an AC220V terminal coil drawing 3.5 VA, it responds in 0.05s. The integrated manifold uses an O8xO5 PU tube to bridge the valve and cylinder. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembly, even though the ISO 15552 barrel itself rates to 1.0 MPa.
This 50mm bore generates 982N of push force at 0.5 MPa and 1374N at 0.7 MPa. By default, the factory valve configuration retracts the piston rod when the coil is energised. You can reposition the valve to extend-when-energised if your cycle logic requires it. The unit switches itself from one electrical signal, eliminating remote plumbing and saving panel space for decentralized machine stations.

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 SAIF50X80-06A Is Used
Decentralized Assembly Stations
Eliminates the need for a central valve bank by switching directly from the AC220V terminal input, drastically reducing tubing runs across large factory layouts.
Compact Clamping Fixtures
Provides 982N of push force at 0.5 MPa within a tight ISO 15552 footprint, making it suitable for precision clamping where external valves would consume excessive space.
Machine Retrofitting
Ideal for upgrading older pneumatic presses where adding a remote valve island is cost-prohibitive, as the integrated 4M210-06 valve manages airflow locally.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X80-06A the Right Choice?
Choose this 50mm bore when 32mm (402N push at 0.5 MPa) is too weak, but 63mm (1559N) is oversized. The SAIF50X80-06A is ideal when a self-valved cylinder beats running separate valve tubing across a large machine. The 1/8" cylinder port and 1/8" valve port keep the envelope compact. For replacements, match the 50mm bore, 80mm stroke, 4M210-06 valve, AC220V terminal coil, PT thread, and no magnet. If you need load holding, note the 5/2 valve only routes air; consider an AirTAC SAIL lock cylinder 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 SAIF50X80-06A FAQ
The 50mm bore generates 982N push force at 0.5 MPa and 1767N at 0.9 MPa. The built-in 4M210-06 5/2 valve has a 14.0 mm2 effective area (Cv 0.78) and a maximum frequency of 5 cycles per second.
By factory default, the rod retracts when the AC220V coil is energised. Because it uses a 5/2 pilot valve rather than a spring, you can reposition the valve on the manifold to switch to extend-when-energised without needing a separate remote valve.
