Airtac SAIF Series Standard Cylinder with Valve SAIF50X900-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X900-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 900mm 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 SAIF50X900-06A
The AirTAC SAIF50X900-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a Cv of 0.78. Driven by an AC220V terminal coil drawing 3.5 VA, it eliminates the need for a separate remote valve. The unit operates within a practical pressure range of 0.15-0.8 MPa, as the integrated valve limits the 1.0 MPa cylinder rating, and achieves speeds of 30-800 mm/s.
Providing 982N of push force at 0.5 MPa, this ISO 15552 dimensionally interchangeable actuator uses a carbon steel piston rod. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The manifold connects to the cylinder via PU tubing (O8 x O5), keeping plumbing compact 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)

|---|---|---|
| 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 SAIF50X900-06A Is Used
Decentralized Assembly Lines
Ideal for large machines where running individual valve tubing back to a central manifold is costly and space-prohibitive.
Long-Stroke Material Handling
The 900mm stroke suits push-off or transfer gates, provided external guides support the rod against side loads.
Retrofit Automation Stations
Drops into existing ISO 15552 footprints while adding local AC220V coil control without extra plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X900-06A the Right Choice?
Choose this 50mm bore when 40mm bore falls short at 628N push force, or step up to 63mm if you need 1559N. A self-valved SAIF beats a separate cylinder and remote valve when panel space is tight and running tubing is costly across large machines. This 900mm stroke demands external guide support to prevent rod side-loading and premature seal wear.
To replace this unit, match the 50mm bore, 900mm stroke, 1/8 cylinder port, 4M210-06 valve, AC220V voltage, terminal entry, PT thread, and no magnet. Note that the 5/2 valve routes air but does not hold the load without live pressure; for position holding, consider the SAIL lock variant.
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 SAIF50X900-06A FAQ
The 50mm bore generates 982N push force at 0.5 MPa and 1767N at 0.9 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78).
No, the integrated 5/2 valve switches the cylinder directly from one AC220V coil signal. Factory default retracts the rod when energised, but you can reposition the valve to extend on signal.
