Airtac SAIF Series Standard Cylinder with Valve SAIF50X225-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X225-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 225mm 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 SAIF50X225-06B
The AirTAC SAIF50X225-06B is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering an effective flow of 14.0 mm2 (Cv 0.78). Driven by a DC24V terminal connection coil drawing 3.0 W, it activates in 0.05 s or less. The cylinder body itself rates to 1.0 MPa, but the practical operating range for this assembled unit is 0.15-0.8 MPa because the internal pilot valve operates within that band.
At 0.5 MPa, the 50 mm bore generates 982 N of push force and 825 N of pull force. The manifold links the valve to the cylinder using an O8 x O5 PU tube, meaning the 1/8" valve port and the 1/4" cylinder port are entirely separate. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend on signal instead. This decentralized design needs only one electrical input to switch itself, eliminating remote plumbing and saving panel space.

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)

| 0.7 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 SAIF50X225-06B Is Used
Decentralized Assembly Stations
Ideal for large machines with multiple stations. The integrated DC24V valve lets each cylinder switch itself locally, drastically reducing main panel wiring and pneumatic tubing runs.
Compact Clamping Fixtures
Delivers 982 N of push force at 0.5 MPa in a tight space. The built-in 4M210 valve eliminates the need to mount a separate valve block nearby, saving valuable fixture real estate.
Retrofit Sorting Diverters
Perfect for upgrading existing conveyor lines where adding external valve islands is impractical. The terminal electrical entry provides a straightforward wiring connection for new automation.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X225-06B the Right Choice?
Choose this self-valved SAIF50X225-06B when a machine layout makes running separate valve tubing too costly or complex. It provides 982 N push force at 0.5 MPa; if your application requires less force, step down to the 40 mm bore (628 N push), or step up to the 63 mm bore (1559 N push) for heavier loads. The DC24V terminal coil is standard for safe control circuits, and the 1/8" PT valve port offers a compact footprint for the 4M210 valve.
Because the 225 mm stroke exceeds 300 mm? No, but at 225 mm it is still important to manage side loads. Use appropriate guide rails to prevent rod binding. Note that the built-in 5/2 valve routes air and holds its position via internal pilot pressure, but it is not a mechanical lock; if you need true load holding, consider the SAIL lock series. For replacements, match the 50 mm bore, 225 mm stroke, 1/8" valve port, DC24V voltage, terminal entry, PT threads, and no magnet (-S).
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 SAIF50X225-06B FAQ
At 0.5 MPa, this 50 mm bore double-acting cylinder provides 982 N of push force and 825 N of pull force. The maximum push force is 1767 N at 0.9 MPa, operating at speeds between 30 and 800 mm/s.
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the 4M210-06 5/2 valve on the manifold block to extend the rod upon signal instead. This decentralized setup requires no separate remote valve.
