Airtac SAIF Series Standard Cylinder with Valve SAIF50X300S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X300S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 300mm 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 SAIF50X300S-06B
The AirTAC SAIF50X300S-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This self-contained assembly delivers a 16.0mm2 orifice (Cv 0.89) and operates on a DC24V terminal coil drawing 3.0W. Equipped with a magnet for position sensing, it interfaces directly with AirTAC CMSE reed and DMSE electronic switches. Although the cylinder body rates to 1.0MPa, the built-in valve limits the practical working pressure to 0.15-0.8MPa.
Providing 982N of push force at 0.5MPa, this unit eliminates the need for a separate remote valve. The manifold uses O8xO5 PU tubing to bridge the 1/4 cylinder port and the 1/8 valve port. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal, offering flexible decentralized control without extra panel plumbing.

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 SAIF50X300S-06B Is Used
Decentralized Assembly Stations
Eliminates remote valve banks on large machines by switching the cylinder directly from a single DC24V signal, minimizing tubing runs.
Space-Tight Diverters
The integrated manifold block saves valuable panel and floor space, fitting neatly into compact conveyor sorting mechanisms.
Retrofit Automation
Ideal for upgrading existing lines where adding external pneumatic plumbing is difficult; just supply air and wire the terminal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X300S-06B the Right Choice?
Choose this 50mm bore when 982N push at 0.5MPa is required; step down to a 40mm bore (628N) for lighter loads, or up to a 63mm bore (1559N) if your application needs more thrust. The SAIF series excels in decentralized stations where running separate valve tubing is costly, saving wiring and panel space. Specify this exact configuration for replacements by matching the 50mm bore, 300mm stroke, 1/8 valve port, DC24V voltage, terminal entry, PT threads, and the -S magnet option.
Because the 300mm stroke exceeds 300mm, ensure adequate guiding to prevent excessive side loads on the rod. Remember that the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, select 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 SAIF50X300S-06B FAQ
The 50mm bore generates 982N push and 825N pull force at 0.5MPa. The built-in 4M210-06 valve has a 14.0mm2 effective area (Cv 0.78) and a maximum frequency of 5 cycles per second.
Yes. The factory setting retracts the piston rod when the DC24V coil is energised, but you can reposition the valve on the manifold to extend the rod upon signal instead. This decentralized design requires no separate remote valve.
